Integumentary Flashcards
epithelial membrane
includes the cutaneous membrane, the muccous membrane, and the serous membrane
cutaneous membrane
skin
mucous membrane
composed of epithelium resting on a loose connective tissue membrane called a lamina propria
serous membrane
composed of a layer of simple squamous epithelium resting on a thin layer of areolar connective tissue
serous fluid
seperates the serous layers
.peritoneum
serosa lining the abdominal cavity and covering its organs
pleura
surrounds the lungs
pericardium
is around the heart
synovial membrane
composed of soft areolar connective tissue and contain no epithelial cells at all
skin
cutaneous membrane
integument
covering
keratin
hardened in order to prevent water loss from the body surface
epidermis
made up of stratified squamous epithelium that is capable of keratinizing or becoming hard and tough
dermis
made up of dense connective tissue
stratum basale
deepest cell layer in the epidermis
stratum spinosum
move from the dermis and become part of the superficial layers the
stratum granulosum
then become this
stratum lucidum
they become flatter and then finially die forming the clear
stratum corneum
20-30 cell layers thick
melanin
pigment that ranges in color from yellow to brown to black
sebaceous glands
found all over the skin except the palms of your hand and the soles of the feet
sebum
mixture of oily substances and fragmented cells
eccrine glands
far more numerous and found all over the body
apocrine glands
largely confined to the axillary and gential areas of the body
hair follicles
compund structures
arrector pili
connect each side of the hair follicle to the dermal tissue
athlete’s foot
an itchy red peeling condition of the skin between the toes resulting from fungus infection
.boils and carbuncles
inflation of hair follicles and sebaceous glands common on the dorsal neck
cold sores
small fluid filled blisters that itch and sting caused by herpes simplex infection
contact dermatitis
itching swelling and redness to the skin progressing to blistering
impetigo
pink, waterfilled, rasied lesions that develop a yellow crust and eventually ruptared
psoriasis
chronic conditioned characterized by overproduction of skin cells that results in reddened epidermal lesions covered with dry silvery scales
Basal cell carcinoma
least malignant and most common skin cancer
Squamous cell carcinoma
arisies from the cells of the stratum spinosum
Malignant melanoma
cancer of melanocytes
