Class 8 - Cell Regulation Flashcards
Epidermis
outer layer of the skin
Cyanosis
blueish colour of skin
Dysplasia
abnormal differentiating of dividing cells; maladaptive process
Cell-cycle specific
cytotoxic agents act on cells in a SPECIFIC phase of the cell cycle
dermis
layer of the skin between the epidermis and the subcutaneous tissue
jaundice
yellowing of the skin
anaplasia
cell differentiation into a more immature form; maladaptive process
neutropenia
reduced number of neutrophils; increases the incidence and severity of infections
subcutaneous layer
layer of fat in the skin
hypothermia
cold
hyperthermia
warm
ischemia
loss of oxygen
nadir
lowest neutrophil count; 10-14 days
basal cell layer
layer of cells in the epidermis, containing basal cells
neoplastic growth
growth of cancer cells
thrombocytopenia
reduced number of platelets; increased risk for serious bleeding
melanocyte
skin cell that produces melanin
diaphoresis
sweating to an unusual degree
benign
tumours that are non cancerous
anemia
reduced number of red blood cells
eccrine glands
sweat glands fo the body
turgor
skins elasticity and mobility
apoptosis
programmed cell death
coagulative
caused by ischemia, free radical, still looks like a cell for awhile
alopecia
hair loss resulting from injury to hair follices
apocrine glands
gland found in the skin, breast, eyelid, and ear
skin mobility
assessed by turgor
stomatisis
inflammation of the oral mucosa
edema
swelling
dehydration
use/lose more fluid than you take in
liquefactive
caused by the body releasing enzymes to kill bacteria causing damage to nearby cells
primary lesions
lesion happens to unaltered skin
brawny edema
swelling that can’t be indented
atrophy
decrease in cell size
caseous
distinct form of coagulative necrosis where tissue is no longer recognizable
secondary lesions
changes to the lesion over time
pruritis
itchiness
hypertrophy
increase in cell size
gangrene
build up of decomposing dead tissue
xerosis
hyperplasia
mitosis
dividing of cells
cell-cycle non-specific
cytotoxic agents that act on the cell cycle in no specific part
pallor
paleness
metaplasia
transformation of cells
growth faction
ratio of proliferating cells to G0 cells
erythema
redness
hyperplasia
multiplication of cells
anasarca
bilateral/generalized edema
