epithelial membranes, connective tissue membranes

cutaneous, serous, mucous

2

epithelial sheet, connective tissue layer

line body cavities and covers the surfaces of organs, a single continuous sheet of tissue that folds itself to 2 distinct layers, secrets a thin watery fluid that reduces friction between the 2 layers and provides lubrication

lines the wall of the thoracic cavity

lines the walls of the abdominal cavity

epidermis is the outermost layer, dermis is deeper and thicker layer of the two

epidermis

protection, temperature regulation, sense organ, excrtion, vitamin D synthesis

Specialized area that is between the epidermis and dermis layer of the skin, glues the 2 layers together, if the junction is weekend or destroyed the skin will fall apart, if that happens in the large area it can lead to serious infection or death

crescent shaped area closest to root

the hair that is present on a newborn

a tiny smooth muscle that contracts when we are scared or cold and causes “goosebumps “

first degree :(typical sunburn)causes minor discomfort and some reddening of the skin. no blistering and minimal tissue destruction second degree:(partial thickness)epidermal layers and upper layers of the dermis are injured.sweat glands, hair follicles and sebaceous glands can be damaged third degree:(full thickness) complete destruction of the epidermis and dermis and continue to the subcutaneous tissue. often involve underlining muscle and bones. not able to feel pain immediately due to the nerve endings are destroyed, but intense pain will soon follow. fluid loss is a serious problem and increase risk of infection because the skin is the first line of defense

lines the wall of the body cavity ( like a wallpaper)

PARIETAL:lines the body cavity (like wallpaper) VISCERAL:covers the surface of the organs PERICARDIUM:serous membrane around the heart

is composed of 2 distinct layers. 1 epithelial layer of tissue and an underlying layer fibrous connective tissue

composed of only the various types of connective tissue.no epithelial cells are in this type of membrane.

specialized area that is between the epidermis and dermis layer of the skin

they are skin receptors

sudoriferous(sweat glands), sebaceous(oil glands)

more numerous and secrete sweat

secrete sebum (oil)

genetic predisposition, uv ray damage the skin cell DNA produces mistakes in the code

squamous cell carcinoma, basal cell carcinoma, malignant melanoma

slow growing tumor of epidermis , begin as painless, raised, hard nodules, if not treated will metastasize

melanoma

most common , usually on upper face, small raised lesion that erodes in canter, may bleed or crust over less likely to spread

most deadly,develops from benign,pigmented mole or excess UV radiation. incidence in US is increasing

basal cell carcinoma
