-ism
process; condition
hyper-
above; excessive
-iasis
abnormal condition
-rrhea
flow, discharge
auto-
self, own
adipocytes
-specialize in formation of fat
collagen
-interwoven elastic protein fibers
-tough but flexible
-delicate in infants, hardens w/ age
melanocytes
-basal layer of epidermis
-contain melanin (black pigment)
-melanin amount = color diff in skin
-darker skin has more active melacytes not more #
-melanin in epidermis = vital for protection against harmful ultraviolet radiation (cause cancer)
sebum
oily/waxy material, lubricates & waterproofs the skin
acne
inflammatory disorder of the sebaceous glands that produces pimples on the skin
albinism
inherited condition that prevents normal production of melanin, resulting in extremely pale skin and white hair
alopecia
hair loss resulting from genetics, normal aging, illness, drugs used to treat certain diseases
cicatrix
scar left by healed wound
cyanosis
blue or purple discoloration of skin or mucous membranes due to insufficient blood oxygen or poor circulation
ecchymosis
black and blue or purpulish bruise caused by ruptured blood vessels beneath the skin
eczema (dermatitis)
acute or chronic inflammatory skin disease characterized by erythema, itchiness, and edema
gangrene
necrosis/death of tissue due to loss of blood supply, followed by bacterial infection
keloid
abnormal, raised, thickened scar
impetigo
bacterial infection characterized by vesicles, pustles, + overcrusted lesions
petechia
round, pinpt spots on the skin caused by intradermal hemorrhage
psoriasis
chronic disease marked by itchy, erythmatous skin w/ silvery patches
pupura
purple or brownish-red rash in which blood leaks from vessels into the skin or mucous membranes
scabies
contagious, parasitic infection of the skin w/ intense pruritis or itching
scleroderma
chronic progressive disease marked by hardening and shrinking of connective tissue, causes edema or pain the muscles + joints
tinea
infection caused by a fungus “ringworn” “athletes foot”
urticaria
hives w/ localized swelling + itching
varicose veins
veins have a twisting appearance due to loss of elasticity “Spider veins)
Vitiligo
loss of pigment in 1+ areas of the skin, creating milky white patches
wart
small, hard, benign skin growth caused by a virus
edema
swelling in parts of your body because of fluid trapped in your tissues
pruritis
severe itching of skin
erythema/erymatous
Redness of the skin caused by increase blood flow in superficial capillaries
cyst
fluid-filled sac
nevus
mole (a small, often slightly raised blemish on the skin made dark by a high concentration of melanin.)
fissure
groove or crack
macule
freckle (overproduction of melanin)
nodule
skin elevation larger than 1 cm in diameter
papule
(pimple) skin elevation with distinct borders + diameters less than 1 cm
polyp
small mushroom like growth, typically benign
vesicle
blister (a small bubble on the skin filled with serum and caused by friction, burning, or other damage.)
pustle
(abscess) small, infected skin elevation, contains pus
ulcer
open sore or erosion of skin or lining of mucous membranes
wheal
(hives) smooth, slightly swollen area that is redder or paler than surrounding skin
basal cell carcinoma
commonly slow growing, malignant tumour, seldom metastasizes/spread to other parts of body
malignant melanoma
cancerous growth composed of melanocytes; beings as an irregular shaped macule then changes color and texture
-level 1, 2, 3, 4 (roman) based on penetration
squamous cell carcinoma
malignant tumor that may grow in other organs lined with epithelial cells
merkle cell carcinoma
a rare aggressive skin cancer that creates firm painless lesions or nodules on a sun-exposed area (usually found on the head, neck, and eyelid).
hives
raised, often itchy, red bumps (welts) on the surface of the skin. They can be an allergic reaction to food or medicine.
benign
not cancerous
Mucous membrane
The moist, inner lining of some organs and body cavities (such as the nose, mouth, lungs, and stomach)
Mucus
A thick, slippery fluid for lubrication, and protection
hemorrhage
an escape of blood from a ruptured blood vessel
malignant
cancerous/cancer
SubQtaneous layer (hypodermous)
-adipocytes
-important in protecting deeper tissues of the body
-heat insulator
-connects dermis to muscles + organs below
-insulates from temp extremes
squamous cell
Flat cell that looks like a fish scale under a microscope. These cells are found in the tissues that form the surface of the skin, the passages of the respiratory and digestive tracts, and the lining of the hollow organs of the body (such as the bladder, kidney, and uterus, including the cervix).
hair in the dermis
-hair shafts located in dermis
-bundles of involuntary muscles called arrector pilli
