Exocrine Glands Flashcards
Simple Glands
sweat glands and sebaceous glands
Compound glands
salivary glands and exocrine pancreas
Holocrine secretion
lysis of cells filled with secretory product
–sebaceous glands of the skin
Apocrine secretion
Shedding of apical cell segment filled with secretory product
Mammary glands
Merocrine secretion
exocytosis of proteins/glycoproteins
sweat glands/salivary glands/exocrine pancreas
Serous cells
Secrete proteins–secretory granules in apical cytoplasm
Mucous cells
Secrete mucin–becomes mucus
Myoepithelial cells
contraction expels secretory product from gland lumen
sweat/salivary/mammary glands
Unicellular glands
Goblet cells–mucin secretion
Multicellular simple glands
Sebaceous glands
Eccrine sweat glands
Apocrine swear glands
Sebaceous glands
simple branched acinar glands–associated with hair follicles
holocrine secretion
origin of acne
Eccrine sweat glands
simple coiled tubular glands
Thermoregulation and excretory–secretion controlled by cholingeric fibers of sum NS
Secretory portion- Pale cells–fluid/Dark cells-proteins/myoepithelial cells-contract to expel product
Conducting portion–re-absorbs NaCl and H2O
Apocrine Sweat glands
simple coiled glands located in axillary/areolar/perineal regions
MEROCRINE secretion- associated with hair shafts
Stimulated by adrenergic nerve fibers
Multicellular compound glands
Salivary glands and exocrine pancreas
Acini- serous cells of salivary gland
Secrete amylase/lysozyme/sIgA/bicarb
Absorb chloride
