a thin, sheetlike structure that covers and prtects the body surface, line body cavities, and cover the inner surfaces of hollow organs. ex (digestive, reproductive, and respiratory )
composed of epithelial tissue and an undelying layer of specialized connective tissue
connective tissue membrane
composed exvlusively of various types of connective tissue; no epithelial cells are present in this type of membrane
3 types of epithelial tissue membrane in the body
1.) cutaneous membrane 2.) serous membrane 3.) mucous membrane
the skin, primary organ of the integumentary system, one of the most important, one of the largest and most visible organ
composed of two distinct layers of tissue. 1st layer lines body cavities and the 2nd covers the organs in those cavities.
very thin, gluelike connective tissue that holds and supports the epithelial cells
epithelial membranes that line body surfaces opening directly to the exterior. ex( lining the respiratory, digestive, urinary and reproductive tracts.)
the transitional area that serves as a point of "fusion" where skin and mucous membranes meet
lining the spaces between bones and joints that are classified as connective tissue membranes
helps reduce friction between the opposing surfaces of bones in teh movable joints. Also known as small cushionlike sacs
nature's most unique proteins. Tough, waterproof material that provides cells in the outer layer of the skin w/ a horny, abrasion- resistant, and protective quality.
the brown pigment. precents the sunds harmful ultraviolet rays from penetrating the interior of the body
exists between the thin epidermal layer of the skin above and the dermal layer below
upper region of the dermis that forms part of the dermal-epidermal junction and forms the ridges and groves of fingerprints
generally located close to the skin surface. Capable of dectecting sensations of light touch.
the more numerous, important, and wide spread sweat glands in the body. They producetransparetn, watery liquid.. also known as sweat
found primarily in the skin in the armpit and in the pigmented skin areas around the genitals
rare form of skin cancer frequently associated with AIDS and other immune deficiencies
most important functions of the skin
1.) protection 2.) temperature regulation 3.) sense organ activity
"rules of nines"
one of the most commonly used methods of determining the extent of a burn injury. Dividing the body into 11 areas of 9% each helps to estimate the amout of skin surface burned in an adult
1st degree burn
causes minor discomfort and some reddening of the skin. epidermis may peel in 1-3 days, no blistering occurs
2nd degree burn
involves the deep epidermal layers and always causes injury to the upper layer of the dermis. Damages sweat glands, hair follicles and sebaceous glands.
