match the tissue type to the integumentary system structure

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 made up of skin, glands, hair, and nails, and it functions primarily to protect and insulate the body. 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. The skin is attached to underlying tissue by the hypodermis, which is a major site of fat storage. Our engaging videos, interactive quizzes, in-depth articles and HD atlas are here to get you top results faster. [citation needed] Keratin is also a waterproofing protein. Match the skin structure to its tissue type. Match these terms with the correct statement or definition: Fat Hypodermis 1. Musculocutaneous vessels arise from intramuscular vasculature after piercing muscles and spreading out in the subcutaneous tissue. The nail plate is completely free distally to the onychodermal band (distal margin of the nail bed). Broadly speaking, the integumentary system is composed of skin and its appendages, subcutaneous tissue, deep fascia, mucocutaneous junctions, and breasts. 3. The major function of the integumentary system is to protect the fish from external injuries and enemies. – The glands produce sweat, which is important for thermoregulation. Structure of skin Integumentary system The integumentary system consists of the skin (integument), the skin appendages which include hair, nail, sweat, sebaceous & mammary glands. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue (Figure 5.1.1). Grounded on academic literature and research, validated by experts, and trusted by more than 1 million users. The majority of sweat glands are eccrine. 9. It is separated from the dermis by the basement membrane. The majority of the skin on the body is keratinized. The bulb consists of two parts: germinal matrix and the upper bulb. 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. Describe the dermis and the 2 major regions that the dermis consists of. 3. 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). Match the text descriptions below with the appropriately feature that is labeled by a letter in the tissue section. Sebaceous glands are small saccular structures located in the dermis, which cover most of the body. The epidermis is _____; that is it has no blood supply of its own, similar to epithelial tissue. Broadly speaking, the integumentary system is composed of skin and its appendages, subcutaneous tissue, deep fascia, mucocutaneous junctions, and breasts. In humans, it accounts for about 12 to 15 percent of total body weight and covers 1.5-2m2 of surface area. Cutaneous ... •Keratin is a protein that makes our skin waterproof. These cells are grouped together in lobules separated by connective tissue. The dermal hair papilla is a cluster of mesenchymal cells giving rise to several capillaries, which form a capillary loop. [2] The deepest layer, the hypodermis, is primarily made up of adipose tissue. Simple Cuboidal Epithelial C. Simple Columnar Epithelial The Nervous System and Nervous Tissue Chapter 13: Anatomy of the Nervous System ... Joint Structure / Articulations The cutaneous circulation consists of many capillary and arterio-venous anastomoses, particularly in the extremities to facilitate thermoregulation. Read more. This layer contains adipose tissue and connective tissue as well as blood vessels, nerves and immune cells. Areolar connective tissue, adipose connective tissuw. Dermis: F & I 5. The integumentary system of fish compries skin and its derivatives. Other than that, the integumentary system organs work together to provide insulation and help in excreting waste from the body. It acts as a protective layer as it protects the entering of pathogens. Mucous Membranes •Surface epithelium type depends on site –Stratified squamous epithelium (mouth, esophagus ... *Primary organ of Integumentary System & largest body organ* Structure: →Epidermis → Dermis 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. It is due to the biotransformation of odourless natural secretions, such as sweat, into volatile odorous molecules. It invaginates into the dermis and is attached to the latter, immediately above it, by collagen and elastin fibers. They occur at orifices in areas like the lips, nostrils, conjunctivae, urethra, vagina, foreskin and anus. The deeper layer … The nail matrix is the structure out of which the nail plate grows. Sweat glands are small, tubular structures located in the skin. Subcutaneous: F & G Simple Squamous Epithelial B. Tendons . It increases the mobility of the skin, it thermally insulates the body, acts as a shock absorber and is a source of energy. Figure: Anatomy of the human skin. View Integumentary System Review Worksheet ... _____ Match the skin structure to its tissue type using the box right. The average rate of hair growth is between 0.2 and 0.44 mm in 24 hours. The skin has an important job of protecting the body and acts as the body's first line of defense against infection, temperature change, and other challenges to homeostasis. There are two major types of hairs: vellus and terminal. There can be more than one answer; choices may be used once ... _____ The epidermis is composed of Keratinized, stratified, squamous, and epithelium cells. Match the following integumentary system glands with their product: apocrine sudoriferous glands. The protein keratin stiffens epidermal tissue to form fingernails. Tissues of the Integumentary System: In the human body there are four tissue types: epithelial, connective, muscular, and nervous tissues. The lunula is the crescent-shape area at the base of the nail, lighter in color as it mixes with matrix cells. These layers serve to give elasticity to the integument, allowing stretching and conferring flexibility, while also resisting distortions, wrinkling, and sagging. 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. They consist of compacted and layered keratin-filled squames (scales). Levels of Body Structure. The skin is also a major sensory organ, containing a large number of nerve terminals for touch, temperature, pain and other stimuli. The hypodermis, otherwise known as the subcutaneous layer, is a layer beneath the skin. Hairs are filamentous cornified structures which grow out of the skin and cover most of the body surface. The commonly affected parts are the nail bed (distal subungual) and nail plate (proximal subungual, white superficial, candidal). One is the papillary layer which is the superficial layer and consists of the areolar connective tissue. b. Bone. The hypodermis is not part of the integumentary system.?? It has a thickness between 1.5 and 5 mm, depending on location. Match the skin structure to its tissue type: Dermis. A nail consists of: the nail plate, nail folds, nail matrix, nail bed and hyponychium. It is actually a downgrowth of the dermis and contiguous with the epithelium. Reading time: 15 minutes. It is essentially composed of a type of cell known as adipocytes specialized in accumulating and storing fats. It consists of three types: direct cutaneous, musculocutaneous and fasciocutaneous systems. A narrower duct emerges from the gland and it opens via a pore on the skin surface. It originates from the nail matrices, found at the base of the nails. Check out our quizzes and learn all those parts in an easy and fun way. It does not contain blood vessels. 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). Connective tissue underlies and supports other tissue types. The epithelial layer is further divided into five layers which are mentioned below:- During the shedding (catagen) phase, the epithelial cells in the hair bulb and the and outer root sheath die in a regulated fashion (apoptosis). The skin not only keeps most harmful substances out, … The epidermis is the top layer of skin made up of epithelial cells. It also protects us a great deal from harm and allows us to sense our surrounding environment. In fact, it is the largest organ of the human body, covering an area of 2 square meters. Integumentary system: want to learn more about it? There can be more than one answer. The epidermis contains melanocytes and gives color to the skin. There can be more than one answer. This article will discuss all of these components in detail together with some clinical notes about them and the integumentary system as … components of sweat plus fatty substances and proteins. The largest part of the innervation of the integumentary system is for the skin to facilitate its great sensorial capabilities. 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 protein __3__ makes the dermis tough and leather like. They are exocrine glands, hence they secrete substances on the epithelial surface via ducts. Apart from understanding the involvement of the immune system, the exact pathogenesis is unknown yet. 1. 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). Recognize or write the functions of the integumentary system. Millions of dead keratinocytes rub off daily. The breasts, also known as the mammary glands, are prominent, superficial structures on the anterior thoracic wall, seen especially in women. If you want to find out more about the anatomy of the breast, have a look at the article below. The hair follicle is the sac containing the hair, out of which it grows. maintains the shape of the body, protects internal organs, is a lever system for muscles to act upon, and is a site of mineral storage and blood-cell formation. Areolar connective tissue, dense irregular connective tissue. The hypodermis also connects the skin to underlying tissues through collagen, elastin, and reticular fibers that extend from the dermis. During the growing (anagen) phase, the follicles produce an entire hair shaft from the dividing cells of the hair bulb. The hypodermis is not part of the integumentary system.?? Also, choices may be used once, more than once, or not at all: A. Epithelial tissue 2. They are located in the subcutaneous tissue overlying the pectoralis major and minor muscles. Also, choices may be used once, more than once, or not at all: The deepest layer of the epidermis also contains nerve endings. The components of the integumentary system receive their innervation, mostly autonomic, via spinal and cranial nerves. Cornified cells from the matrix are gradually extruded distally to form the nail plate. [4][5] Functions include: It distinguishes, separates, and protects the organism from its surroundings. 2. Sometimes called subcutaneous tissue. Epidermis: D 4. The dermis has two layers. 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. Read more. 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. Integumentary System: 2. Skeletal 2. and grab your free ultimate anatomy study guide! There is a perfect match between the nail bed and plate, forming a seal, which prevents microbial invasion and debris collection. Many chromatophores are also stored in this layer, as are the bases of integumental structures such as hair, feathers, and glands. Anatomy & Physiology: BIO 161 / 162. The specialized cells that produce the pigments that contribute to skin color are called __4__. Write the names of the diagnostic terms and pathologies The dermis is directly attached to the periosteum of the distal phalanx and it is richly vascularized. No differentiation or apoptosis happens. 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. It connects the integument (epidermis and dermis) to organs and muscles in the body. 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. 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]. The nail bed consists of two layers: the epidermis and dermis. 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. Nails are homologous to the stratum corneum of the epidermis and contain a variety of minerals, such as calcium. CONTENT LEARNING ACTIVITY Hypodermis ?? Bromhidrosis is a condition characterized by an unpleasant body odour. Adrian Rad BSc (Hons) ... Four Types of Tissues . The integumentary system is the body system which surrounds you, both literally and metaphorically speaking. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the body. Are you struggling with all the parts of the integumentary system? 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. The pathology also involves abnormal changes of the apocrine glands. The hair bulb is the lowest expanded extremity of the hair follicle that fits like a cap over the dermal hair papilla, enclosing it. Differentiation of the hair shaft also stops, and the bottom of it becomes sealed into a structure called the club. Kenhub. 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. Kim Bengochea, Regis University, Denver, Author: 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. It is made up of closely packed epithelial tissue. Title: Apr 6-11:13 AM (7 of 33) Roles of 12 Body Systems- Match the System to its Role 1. Uruj Zehra MBBS, MPhil, PhD The other is the reticular layer which is the deep layer of the dermis and consists of the dense irregular connective tissue. Similar to eccrine glands, apocrine glands also consist of a secretory coil. Composed of fat and loose connective tissue, this layer of the skin insulates the body and cushions and protects internal organs and bones from injury. Connective tissue 3. The hypodermis is filled with subcutaneous nerves, vessels and lymphatics. 1. The skin greatly assists in locomotion and manipulation due to its good frictional properties given by its texture and elasticity. 2. The ducts can also open directly on the surface of the skin, as seen on the lips and buccal mucosa. The germinal matrix consists of pluripotent keratinocytes, which gives rise to the upper bulb. Onychomycoses are fungal infections and the most common pathologies affecting the nails. These are regions of the body where there is a transition from mucosa to skin. Match the following structure with its primary tissue type: reticular layer of the dermis. Most cells of the epidermis are __2__. 2. The nail plate is a rectangular and convex structure embedded within the nail folds. Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules. This hair type is most easily observed on children and adult women and is colloquially known as “peach fuzz”. 8.The dermis is composed of (connective / epithelial) tissue. This type of cell produces the pigments which give skin its color: _____. Match these terms with the correct statement or definition: Fat Hypodermis 1. Its main functions are protection, absorption of nutrients, and homeostasis. The growth, rest and shedding of hair follicles occurs in cyclical stages of variable duration. They are long, unbranched, tubular structures with a highly coiled secretory portion situated deep in the dermis. Nails grow from a thin area called the nail matrix at an average of 1 mm per week. The subcutaneous tissue, also called the hypodermis, is a layer of adipose tissue attached to the deep aspect of the dermis. The skin and its associated structures, hair, sweat glands and nails make up the integumentary system. Non-keratinized cells allow water to "stay" atop the structure. Match the skin structure to its tissue type: Subcutaneous. CONTENT LEARNING ACTIVITY Hypodermis ?? The skin has a significant capacity for renewal and crucial roles for the normal functioning of the human body. Integumentary System (includes: skin, hair, nails) ... § There are four primary tissue types: 1. At such regions, epithelium transitions to epidermis, lamina propria changes to dermis and smooth muscle becomes skeletal muscle. The hypodermis participates, passively at least, in thermoregulation since fat is a heat insulator. The innermost layer of the skin is the hypodermis or subcutis. Ligaments. The skin is the largest organ of the body. It also contains numerous sensory nerve endings, such as Merkel endings and Meissner’s corpuscles. The direct cutaneous are derived directly from the main arterial trunks and drain into the main venous vessels. 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. Skeletal, Muscular, Integumentary Test REVIEW.
