Integumentary System (in-teg-yoo-MEN-tar-ee SYS-tem) |
The skin, or cutaneous membrane, is a sheetlike organ composed of two primary layers; the dermis and epidermis. |
|
|
Epidermis (ep-ih-DER-mis) |
A. The outermost layer of the skin. B. Tightly packed epithelial cells. C. Contains keratin, waterproof material that protects the skin. D. Contain melanin; pigment or color of skin.
|
|
|
Dermis (DER-mis) |
Deeper & Thicker layer of skin containing connective tissue, nerves, fingerprints, follicles, sebaceous gland (oil gland), and sweat glands |
|
|
Dermal papillae (DER-mal pah-PIL-ah) |
Tiny bumps in the upper region of the dermis that forms part of the dermal-epidermal junction and produces the ridges and grooves of fingerprints. |
|
|
Dermal-Epidermal Junction (DER-mal-EP-ih-der-mal JUNK-shun) |
Junction between the thin epidermal layer of the skin and the dermal layer providing support for the epidermis. |
|
|
Arrector pili (ah-REK-tor PYE-lye) |
smooth muscles of the skin that are attached to hair follicles that create "goose bumps" when contracted by cold or eerie feelings. |
|
|
Lanugo-Latin for "down" (lah-NOO-go) |
Newborn infant hair |
|
|
Melanin (MEL-ah-nin) |
Brown skin pigment. Prevents Ultraviolet rays from penetrating the interior of the body. |
|
|
hair papilla (hayr pah-PIL-ah) |
small, cap-shaped cluster of cells located at the base of the follicle where hair growth begins. |
|
|
tactile corpuscle / Meissner corpuscle (TAK-tyle KOR-pus-ul) / (MYZ-ner KOR-pus-ul) |
the large sensory neuron of the skin for detecting sensations of light touch. |
|
|
sebum (SEE-bum) |
secretion of the sebaceous gland; AKA "nature's skin cream" |
|
|
eccrine sweat gland (EK-rin swet gland) |
a group of small sweat glands distributed all over the body surface. |
|
|
apocrine sweat gland (AP-oh-krin swet gland) |
type of sweat gland located in the axilla (arm pit) and genital regions; the glands enlarge and begin to function at puberty. |
|
|
Most important functions of the skin |
Protection Temperature Regulation Senses organ activity Excretion Synthesis of Vitamin D
|
|
|
lamellar corpuscle / Pacini corpuscle (lah-MEL-ar KOR-pus-ul) |
sensory receptor the detects pressure on the surface of the skin. |
|
|
Sudoriferous glands (soo-doh-RIF-er-ous gland) |
Sweat glands classified into two groups: A. eccrine (widespread over the body) B. apocrine (Armpit and genitals) |
|
|
Subcutaneous tissue (sub-kyoo-TAY-nee-usTISH-yoo) |
tissue below the layers of the skin; made up of fat and loose connective tissue AKA: superficial fascia or hypodermis |
|
|
Nails |
Nail Body-visible part of the nail Root-lies in a groove and is hidden by a fold of skin called the cuticle. Lunula "little moon"-crescent-shaped white area at the root of the nail. "little moon" |
