View Integumentary System Review Worksheet ... _____ Match the skin structure to its tissue type using the box right. They occur at orifices in areas like the lips, nostrils, conjunctivae, urethra, vagina, foreskin and anus. Kim Bengochea, Regis University, Denver, Author: It has a thickness between 1.5 and 5 mm, depending on location. Match the skin structure to its tissue type. The lunula is the crescent-shape area at the base of the nail, lighter in color as it mixes with matrix cells. Match the text descriptions below with the appropriately feature that is labeled by a letter in the tissue section. Bone. Subcutaneous: F & G Simple Squamous Epithelial B. The bulb consists of two parts: germinal matrix and the upper bulb. The Nervous System and Nervous Tissue Chapter 13: Anatomy of the Nervous System ... Joint Structure / Articulations The integumentary system has multiple roles in maintaining the body's equilibrium. Musculocutaneous vessels arise from intramuscular vasculature after piercing muscles and spreading out in the subcutaneous tissue. Match these terms with the correct statement or definition: Fat Hypodermis 1. In this anatomy course, part of the Anatomy XSeries, you will learn how the components of the integumentary system help protect our body (epidermis, dermis, hair, nails, and glands), and how the musculoskeletal system (bones, joints, and skeletal muscles) protects and allows the body to move. Sweat glands are small, tubular structures located in the skin. Integumentary system: want to learn more about it? The integumentary system is made up of skin, glands, hair, and nails, and it functions primarily to protect and insulate the body. Write terms for selected stru ctures of the integumentary system or match them with their descriptions. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue (Figure 5.1.1). The epidermis is the top layer of skin made up of epithelial cells. The skin is also a major sensory organ, containing a large number of nerve terminals for touch, temperature, pain and other stimuli. The hair loss can affect the entire scalp (Alopecia totalis) or the entire epidermis (Alopecia universalis). These include Pacinian corpuscles, Meissner’s corpuscles and a large variety of other receptors for a range of stimuli. ... Four Types of Tissues . CONTENT LEARNING ACTIVITY Hypodermis ?? Possible diseases and injuries to the human integumentary system include: Organ system that protects the body comprising the skin and its appendages (including hair, scales, feathers, hooves, and nails), "Integumentary" redirects here. It is an extensive sensory organ, which forms an outer, protective coat around the entire external surface of the body. Connective tissue 3. They consist of compacted and layered keratin-filled squames (scales). The hair follicles go through a cyclic activity of hair growth and loss. The skin and its associated structures, hair, sweat glands and nails make up the integumentary system. 8.The dermis is composed of (connective / epithelial) tissue. It is separated from the dermis by the basement membrane. It has a variety of additional functions; it may serve to waterproof, and protect the deeper tissues, excrete wastes, and regulate body temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. The protein keratin stiffens epidermal tissue to form fingernails. Structure of skin The skin is attached to underlying tissue by the hypodermis, which is a major site of fat storage. The Stratum Corneum: The outermost layer of skin consisting of dead and Keratinization cells. The innermost layer of the skin is the hypodermis or subcutis. Read more. This gas exchange system, where gases simply diffuse into and out of the interstitial fluid, is called integumentary exchange. It connects the integument (epidermis and dermis) to organs and muscles in the body. Introduction to the musculoskeletal system, https://en.wikipedia.org/wiki/Mucocutaneous_zone, Nail plate, nail folds, nail matrix, nail bed, hyponychium, Adipose tissue that increases skin mobility, insulates the body, and acts as a shock absorber, Pacinian corpuscles, Meissner corpuscles, specific stimuli receptors, Glassy membrane (basement membrane of hair follicle). 2. The epidermis is the topmost layer of skin that can touch, see and feel. Beneath this, the dermis comprises two sections, the papillary and reticular layers, and contains connective tissues, vessels, glands, follicles, hair roots, sensory nerve endings, and muscular tissue. The scales, coloration and some special structures like the electric organs, poisonous glands, and phosphorescent organs are the integumentary derivatives. It increases the mobility of the skin, it thermally insulates the body, acts as a shock absorber and is a source of energy. The major cell of the epidermis is the keratinocyte, which produces keratin, a fibrous protein that aids in skin protection. The integumentary system is the body system which surrounds you, both literally and metaphorically speaking. The skin has a significant capacity for renewal and crucial roles for the normal functioning of the human body. Connective epithelia nervous muscle _____ Functions in helping different parts of the body move _____ Functions in communication The epidermis is the outermost layer, providing the initial barrier to the external environment. 1. Dermis: F & I 5. During the shedding (catagen) phase, the epithelial cells in the hair bulb and the and outer root sheath die in a regulated fashion (apoptosis). 3. It is made up of closely packed epithelial tissue. The epidermis has no blood supply and it is nourished by diffused oxygen from surrounding air. The breasts, also known as the mammary glands, are prominent, superficial structures on the anterior thoracic wall, seen especially in women. Skeletal, Muscular, Integumentary Test REVIEW. 2. Hairs are filamentous cornified structures which grow out of the skin and cover most of the body surface. Adrian Rad BSc (Hons) The hair bulb is the lowest expanded extremity of the hair follicle that fits like a cap over the dermal hair papilla, enclosing it. The skin is the largest organ of the body. As the cells from the matrix migrate apically and differentiate further, they form several structures and layers. Skin: Tissue creating an external covering of the body. It is an effective barrier against potential pathogens and protects against mechanical, chemical, osmotic, thermal and ultraviolet radiation damage (through melanin). The integumentary system is composed of skin and its appendages, subcutaneous tissue, deep fascia, mucocutaneous junctions, and breasts. – 2021 Last reviewed: October 29, 2020 The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue (Figure 4.1). The protein __3__ makes the dermis tough and leather like. Sebum is crucial in the epidermal barrier and the skin’s immune system. Differentiation of the hair shaft also stops, and the bottom of it becomes sealed into a structure called the club. The integumentary system of fish compries skin and its derivatives. It invaginates into the dermis and is attached to the latter, immediately above it, by collagen and elastin fibers. Connective tissue underlies and supports other tissue types. Also, choices may be used once, more than once, or not at all: A. The integumentary system is composed of the following parts: The skin is the largest component of this system. Hairs are important in sensing, thermoregulation and protection against injury and solar radiation. The dermis is the middle layer of skin, composed of dense irregular connective tissue and areolar connective tissue such as a collagen with elastin arranged in a diffusely bundled and woven pattern. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. This article will discuss all of these components in detail together with some clinical notes about them and the integumentary system as a whole. They are long, unbranched, tubular structures with a highly coiled secretory portion situated deep in the dermis. Recognize or write the meanings of Chapter 12 word parts and use them to build and analyze terms. However, the duct emerging from the gland opens inside the pilary canal above the duct of the sebaceous gland or directly on the surface of the skin. Fasciocutaneous blood vessels consist of perforating branches from vessels located deep to the deep fascia. Vellus hairs do not project beyond their follicles in some of the areas, however, they are short and narrow and cover most of the surface of the body. There are two major types of hairs: vellus and terminal. Beneath these two layers lies the hypodermis, composed of loose connective tissue (adipose and areolar). It originates from the nail matrices, found at the base of the nails. Other than that, the integumentary system organs work together to provide insulation and help in excreting waste from the body. Areolar connective tissue, dense irregular connective tissue. It also contains numerous sensory nerve endings, such as Merkel endings and Meissner’s corpuscles. 2. Kenhub. The fungi usually reside on the scales of the skin of the palms and soles and send hyphae that penetrate the hyponychium to invade the nail. For the part of the female reproductive system of seed plants, see, Martini & Nath: "Fundamentals of Anatomy & Physiology" 8th Edition, pp.158, Pearson Education, 2009, https://en.wikipedia.org/w/index.php?title=Integumentary_system&oldid=1002287496, Articles with unsourced statements from January 2018, Articles with unsourced statements from March 2017, Creative Commons Attribution-ShareAlike License, Act as a receptor for touch, pressure, pain, heat, and cold (see, Formation of new cells from stratum germinativum to repair minor injuries, This page was last edited on 23 January 2021, at 18:37. This hair type is most easily observed on children and adult women and is colloquially known as “peach fuzz”. The hypodermis participates, passively at least, in thermoregulation since fat is a heat insulator. Sweating also assists this process. [1], The human skin (integument) is composed of at least two major layers of tissue: the epidermis and dermis. The skin greatly assists in locomotion and manipulation due to its good frictional properties given by its texture and elasticity. Sometimes called subcutaneous tissue. Similar to eccrine glands, apocrine glands also consist of a secretory coil. Areolar connective tissue, adipose connective tissuw. Our engaging videos, interactive quizzes, in-depth articles and HD atlas are here to get you top results faster. The integumentary system is supplied by the cutaneous circulation, which is crucial for thermoregulation. The skin not only keeps most harmful substances out, … Write the names of the diagnostic terms and pathologies Epidermis: D 4. Nerves in the Integumentary System By Janet Rae-Dupree, Pat DuPree Skin is jam-packed with components; it has been estimated that every square inch of skin contains 15 feet of blood vessels, 4 yards of nerves, 650 sweat glands, 100 oil glands, 1,500 sensory receptors, and more than 3 million cells with an average life span of 26 days that are constantly being replaced. The integumentary system consists of the skin, hair, nails, the subcutaneous tissue below the skin,and assorted glands.The most obvious function of the integumentary system is the protection that the skin gives to underlying tissues. 9. 4. Mucous Membranes •Surface epithelium type depends on site –Stratified squamous epithelium (mouth, esophagus ... *Primary organ of Integumentary System & largest body organ* Structure: →Epidermis → Dermis b. If you want to find out more about the anatomy of the skin, have a look at this article. [4][5] Functions include: It distinguishes, separates, and protects the organism from its surroundings. The nail plate is a rectangular and convex structure embedded within the nail folds. The commonly affected parts are the nail bed (distal subungual) and nail plate (proximal subungual, white superficial, candidal). • They are exocrine glands, hence they secrete substances on the epithelial surface via ducts. There is a perfect match between the nail bed and plate, forming a seal, which prevents microbial invasion and debris collection. It consists of three types: direct cutaneous, musculocutaneous and fasciocutaneous systems. Cutaneous ... •Keratin is a protein that makes our skin waterproof. 7. “I would honestly say that Kenhub cut my study time in half.” This condition is closely linked to excessive sweating (hyperhidrosis). The hypodermis is the “connection” layer. The hair follicle is the sac containing the hair, out of which it grows. Each word is used twice. Sebaceous glands secrete sebum, which is an oily and fatty secretion. It is the system that can instantly tell us whether someone is young or old, someone’s ethnicity or race or if he/she has been on holidays recently. They also occur in men but are functionless. These cells are grouped together in lobules separated by connective tissue. They are located in the subcutaneous tissue overlying the pectoralis major and minor muscles. Match the skin structure to its tissue type: Dermis. The distal margin of the nail bed is called the onychodermal band. The nail matrix is the structure out of which the nail plate grows. Cartilage. [2] The dermal layer provides a site for the endings of blood vessels and nerves. The glands produce sweat, which is important for thermoregulation. The cutaneous circulation consists of many capillary and arterio-venous anastomoses, particularly in the extremities to facilitate thermoregulation. It specifically contains the platysma muscle in the head and neck. This layer contains adipose tissue and connective tissue as well as blood vessels, nerves and immune cells. Also, the stratum corneum is the top part of the epidermis. The nail folds are the borders of the nail plate, located laterally and proximally, which are continuous around the nail plate. If you look in the mirror you see it, if you look anywhere on your body you see and if you look around you in the outside world, you see it. The hair bulb generates the hair and its inner root sheath. Terminal hairs are longer, thicker and more heavily pigmented. Integumentary System (includes: skin, hair, nails) ... § There are four primary tissue types: 1. Check out our quizzes and learn all those parts in an easy and fun way. A narrower duct emerges from the gland and it opens via a pore on the skin surface. Onychomycoses are fungal infections and the most common pathologies affecting the nails. The skin is anatomically organized as follows, from superficial to deeper layers: (Memorise these layers with the mnemonic: "British and Spanish Grannies Love Cornflakes", see video below). Substantial collagen bundles anchor the dermis to the hypodermis in a way that permits most areas of the skin to move freely over the deeper tissue layers.[3]. In fact, it is the largest organ of the human body, covering an area of 2 square meters. The hypodermis is not part of the integumentary system.?? Grounded on academic literature and research, validated by experts, and trusted by more than 1 million users. The other is the reticular layer which is the deep layer of the dermis and consists of the dense irregular connective tissue. The major function of the integumentary system is to protect the fish from external injuries and enemies. ... § Three types of muscle tissue that vary in structure, location, and control mechanisms. (The hypodermis or subcutaneous layer is not part of the skin[citation needed].) Also, choices may be used once, more than once, or not at all: These layers serve to give elasticity to the integument, allowing stretching and conferring flexibility, while also resisting distortions, wrinkling, and sagging. These are large glands specifically located in the axillae, perianal region, nipples, periumbilical region, prepuce, scrotum, mons pubis, labia minora, nail bed, penis and clitoris. Title: Mar 26-10:37 AM (6 of 33) The 12 Organ Systems. Image Source: Wikipedia . Apart from understanding the involvement of the immune system, the exact pathogenesis is unknown yet. It is actually a downgrowth of the dermis and contiguous with the epithelium. Nails are homologous to the stratum corneum of the epidermis and contain a variety of minerals, such as calcium. It does not contain blood vessels. Bromhidrosis is a condition characterized by an unpleasant body odour. The only skin on the body that is non-keratinized is the lining of mucous membranes, such as the inside of the mouth. The two basic tissues of which the skin is composed are dense connective tissue, which makes up the dermis, and __1__, which forms the epidermis. The subcutaneous tissue, also called the hypodermis, is a layer of adipose tissue attached to the deep aspect of the dermis. All rights reserved. Tissues of the Integumentary System: In the human body there are four tissue types: epithelial, connective, muscular, and nervous tissues. Alopecia areata is a non scarring, autoimmune condition which results in hair loss on the scalp and/or the body. Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules. During the resting (telogen) phase, the hair follicles lie dormant. Cartilage. The Integumentary system: Is an organ system consisting of skin and it's associated structures. Nails grow from a thin area called the nail matrix at an average of 1 mm per week. Register now Cornified cells from the matrix are gradually extruded distally to form the nail plate. Skeletal System: 3. Match these terms with the correct statement or definition: Fat Hypodermis 1. Non-keratinized cells allow water to "stay" atop the structure. The integumentary system comprises the skin and its appendages acting to protect the body from various kinds of damage, such as loss of water or damages from outside. This article will discuss all of these components in detail together with some clinical notes about them and the integumentary system as … The majority of sweat glands are eccrine. The dermis has two layers. Epidermis: The upper layer of skin composed of t he stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum germinativum. It is due to the biotransformation of odourless natural secretions, such as sweat, into volatile odorous molecules. Skeletal 2. Reading time: 15 minutes. Are you struggling with all the parts of the integumentary system? Integumentary System: 2. Most cells of the epidermis are __2__. The epidermis contains melanocytes and gives color to the skin. Millions of dead keratinocytes rub off daily. Lab 3: Integumentary System Search this Guide Search. Match the skin structure to its tissue type. At such regions, epithelium transitions to epidermis, lamina propria changes to dermis and smooth muscle becomes skeletal muscle. These are regions of the body where there is a transition from mucosa to skin. If you want to find out more about the anatomy of the breast, have a look at the article below. The hypodermis also connects the skin to underlying tissues through collagen, elastin, and reticular fibers that extend from the dermis. No differentiation or apoptosis happens. Epithelial tissue 2. Describe the dermis and the 2 major regions that the dermis consists of. and grab your free ultimate anatomy study guide! Uruj Zehra MBBS, MPhil, PhD Connective tissue membranes –Synovial membranes. Match the skin structure to its tissue type: Epidermis. Many chromatophores are also stored in this layer, as are the bases of integumental structures such as hair, feathers, and glands. Stratified squamous epithileal. Levels of Body Structure. The specialized cells that produce the pigments that contribute to skin color are called __4__. [2] The deepest layer, the hypodermis, is primarily made up of adipose tissue. Simple Cuboidal Epithelial C. Simple Columnar Epithelial Recognize or write the functions of the integumentary system. [citation needed] Keratin is also a waterproofing protein. The fats contained in the adipocytes can be put back into circulation, via the venous route, during intense effort or when there is a lack of energy-providing substances, and are then transformed into energy. The deeper layer … Each layer completely encloses the previous one situated more internally. Match the following integumentary system glands with their product: apocrine sudoriferous glands. The nail bed extends between the lunula (crescent shaped, white area of the nail bed) and the hyponychium (area under the free edge of the nail plate). Digestive System: 4. The deepest layer of the epidermis also contains nerve endings. The epidermis is _____; that is it has no blood supply of its own, similar to epithelial tissue. 3. Its main functions are protection, absorption of nutrients, and homeostasis. The skin is attached to underlying tissue by the hypodermis, which is a major site of fat storage. Shedding or loss of club hair happens when the cycle is re-initiated and the newly growing hair follicle pushes the old one out. The skeletal system consists of: B. ones . This Bodytomy post has more information. Several areas of the body like the palms, soles, flexor surface of the digits and specific parts of the reproductive organs are devoid of hairs. Small-bodied invertebrates of aquatic or continually moist habitats respire using the outer layer (integument). The average rate of hair growth is between 0.2 and 0.44 mm in 24 hours. The integumentary system includes hair, scales, feathers, hooves, and nails. 1. Tendons . The majority of the skin on the body is keratinized. In structure, it consists of a keratinized stratified squamous epithelium; four types of cells: keratinocytes, melanocytes, Merkel cells, and Langerhans cells. Title: Apr 6-11:13 AM (7 of 33) Roles of 12 Body Systems- Match the System to its Role 1. The integumentary system forms a protective barrier between the external environment and the inner tissues. The nail bed consists of two layers: the epidermis and dermis. It is essentially composed of a type of cell known as adipocytes specialized in accumulating and storing fats. There can be more than one answer. Broadly speaking, the integumentary system is composed of skin and its appendages, subcutaneous tissue, deep fascia, mucocutaneous junctions, and breasts. The arrangement and cohesion of the squames are responsible for the hardness of nails. The skin not only keeps most harmful substances out, … They are mostly observed on males but also in the axillary and pubic regions of both sexes. They consist of a cluster of secretory acini, which is continued by a duct which opens into the dermal pilary canal of the hair follicle. The skin and its accessory structures make up the integumentary system, which provides the body with overall protection. The epithelial layer is further divided into five layers which are mentioned below:- The pathology also involves abnormal changes of the apocrine glands. In humans, it accounts for about 12 to 15 percent of total body weight and covers 1.5-2m2 of surface area. This type of cell produces the pigments which give skin its color: _____. The hypodermis acts as an energy reserve. All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the body. Title: Apr 1-8:22 PM (11 of 33) Epithelial Tissue . There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Broadly speaking, the integumentary system is composed of skin and its appendages, subcutaneous tissue, deep fascia, mucocutaneous junctions, and breasts. CONTENT LEARNING ACTIVITY Hypodermis ?? The hypodermis, otherwise known as the subcutaneous layer, is a layer beneath the skin. It acts as a protective layer as it protects the entering of pathogens. The hypodermis is filled with subcutaneous nerves, vessels and lymphatics. The germinal matrix consists of pluripotent keratinocytes, which gives rise to the upper bulb. Anatomy & Physiology: BIO 161 / 162. There are two types of sweat glands, eccrine and apocrine and each one produces a different type of sweat. The skin and its accessory structures make up the integumentary system, which provides the body with overall protection. Ligaments. There can be more than one answer; choices may be used once ... _____ The epidermis is composed of Keratinized, stratified, squamous, and epithelium cells. The hypodermis is not part of the integumentary system.?? There can be more than one answer. The growth, rest and shedding of hair follicles occurs in cyclical stages of variable duration. From the interior to the exterior, these include: You can image these layers as tree rings in a cross-section of the hair follicle since they are concentric cylinders. Directions: Match the tissue to its functions and locations. It also protects us a great deal from harm and allows us to sense our surrounding environment. A nail consists of: the nail plate, nail folds, nail matrix, nail bed and hyponychium. It is histopathologically characterized by telogenic (dormant) hair follicles and infiltrating inflammatory lymphocytes. Match the skin structure to its tissue type: Subcutaneous. The direct cutaneous are derived directly from the main arterial trunks and drain into the main venous vessels. The cuticle (eponychium) is an extension of the proximal nail fold located on the dorsal aspect of the nail plate, overlying the root of the nail.
