Describe three physiological roles played by hair. What factors determine the texture of hair? Even when the body does not appear to be noticeably sweating, approximately 500 mL of sweat (insensible perspiration) are secreted a day.
Digestive System The skin synthesizes vitamin D (from exposure to the sun) therefore providing this vital nutrient to the digestive system. During the growing (anagen) phase, the follicles produce an entire hair shaft from the dividing cells of the hair bulb. The nail bed consists of two layers: the epidermis and dermis. Associated Glands [ edit | edit source]. During the shedding (catagen) phase, the epithelial cells in the hair bulb and the and outer root sheath die in a regulated fashion (apoptosis). Cells tissues and integument answer key class. Sensation: The skin contains nerve endings that detect touch, pressure, pain, heat, and cold. The nerve endings in the dermis detect sensations, and thus play a role in the protection of the skin, by sounding an alarm when the skin is exposed to things such as a potential burn.
Each layer completely encloses the previous one situated more internally. This leads to the buildup of scaly, red, and itchy patches of skin. The dermis, which is responsible for the elasticity and resilience of the skin, exhibits a reduced ability to regenerate, which leads to slower wound healing. 16 ac), or a combination of the two, sweat glands will be stimulated by the sympathetic nervous system to produce large amounts of sweat, as much as 0. Keratin helps protect tissues, organs, and structures from injury, like: Cuts Scratches Abrasions Fatty Layer Protection The fatty layer of the skin helps protect against trauma to the underlying tissues and organs by serving as a shock absorber, buffering some of the impact of some types of injuries (such as those caused by blunt force). The direct cutaneous are derived directly from the main arterial trunks and drain into the main venous vessels. Integumentary system: Definition, diagram and function. The cells are long and narrow. A gland can be classified as an endocrine gland, a ductless gland that releases secretions directly into surrounding tissues and fluids (endo- = "inside"), or an exocrine gland whose secretions leave through a duct that opens to the external environment (exo- = "outside"). Your integumentary system stores fat, water, glucose and vitamin D, and helps support your immune system to protect you from diseases. Mnemonic: British and Spanish Grannies Love Cornflakes. The skin and accessory structures perform a variety of essential functions, such as protecting the body from invasion by microorganisms, chemicals, and other environmental factors; preventing dehydration; acting as a sensory organ; modulating body temperature and electrolyte balance; and synthesizing vitamin D. The underlying hypodermis has important roles in storing fats, forming a "cushion" over underlying structures, and providing insulation from cold temperatures. The epidermis, in contrast, does not contain any of these structures with the exception of sensory receptor cells called Merkel cells.
Sorry, preview is currently unavailable. The outermost layer of the epidermis is the stratum corneum, which consists of flat, dead, tightly packed keratinocytes. 5.3 Functions of the Integumentary System - Anatomy and Physiology 2e | OpenStax. Skin structure–function relationships and the wound healing response to intrinsic aging. Absorbs and helps heal abrasions, cuts and other injuries.

Such glands releasing both serous and mucous secretions are often referred to as seromucous glands. For example, the skin helps protect the body from pathogens; nails help enhance sensation by providing counterforce; and hair helps to maintain body temperature by preventing heat loss from the head. The selective permeability of the epidermis is a benefit because it allows the absorption of medications via topical ointments and skin patches. Ch. 4 Review Questions - Anatomy and Physiology | OpenStax. The only living part of a hair is the hair root. Eccrine sweat functions to cool the body.

For example, every person's skin is comprised of different types, including: Thick and hairless: Located on body parts that are frequently used and involve a lot of friction (such as the soles of the feet and palms of the hands). If overexposure to the sun occurs, inflammation occurs and the skin becomes reddened and flushed in response to dilatation of the blood vessels in the dermis. The Pharmacology Education Partnership. The integumentary system has many specific roles in its involvement in helping to protect and regulate the body's internal functions.
