Epithelial Flashcards
Simple Cuboidal
Kidney tubules and ducts of some glands (salivary, thyroid, pancreas, liver)
Simple Columnar
Lines uterus/fallopian tubes, stomach and intestines
Psudostratified Columnar
Upper respiratory tract (trachea, bronchi, bronchioles)
Stratified Squamous
Outer layer of skin, mouth, throat, vagina, anal canal
Stratified Cuboidal
Mammary glands, sweat glands, salivary glands, and pancreas
Stratified Columnar
Vas deferens, pharynx, junction of distal esophagus and cardiac sphincter
Transitional
Urinary bladder
Elongated cells, nuclei on basement of membrane, microvilli, cilia
Absorber and cilia moves things
Simple columnar
Single, thin, flat, permeable
Good for diffusion
Simple squamous
Single, cube-shaped, central nuclei, single ring
Secretion & absorption
Simple cuboidal
Looks like more than one layer but it’s not, nuclei not all on bottom, cilia, goblet cells
Sweep debris, goblet cells produce mucin
Psudostratified columnar
Flattened layerS of cells
Wear and tear, friction, exposure, protect from fluid loss and invasion
Stratified squamous
2-3 layers of cuboidal
Great protection, secretors
Stratified cuboidal
Several layers of columnar
Very rare in the body
Stratified columnar
Designed to return to normal size
Transitional
80% of skin cancer, usually caused by too much exposure before age 20, looks like a pimple that won’t go away
99% cure rate
Basal cell carcinoma
15% of skin cancer, too much sun exposure, red, scaly, may bleed, doesn’t heal
99% cure rate
Squamous cell carcinoma
3-5% of skin cancer, sun exposure and genetic link, grows down through basement membrane, metastasis
Deadly, early detection
Malignant melanoma
ABCD
Asymmetry, border, color, diameter
Top part of epidermis is burned, irritated nerve endings
Painful, red, no blisters, 3-7 days, aloe Vera and cool compress
1st degree
Epidermis and dermis burned
Painful, red, blisters, peeling, 7-10 days, cool compress aloe Vera
2nd degree
Entire thickness of epidermis and dermis
No pain, whitish/grey color, skin slippage and oozing of fluid, months-1 year
3rd degree
Rule of nines
Determining and relaying percent of body burned
Cutaneous membrane
Tarp over boat, skin
Mucous membrane
Lines openings to outside (digestive, respiratory, urinary, reproductive), cells that contain mucous
Serous membrane
Two layered w/ potential space between
Parietal- lines walls of cavities
Visceral- wraps around organs
Serous fluid reduces friction
Simple Squamous
Lines inside of blood vessels, heart, capillaries, alveoli
