Document Summary
Simple epithelium: simple squamous thinnest kind a. In alveoli, heart, blood vessels, and kidney: simple cuboidal a. In glands, pancreas, kidney tubules, and lining of ovary: microvilli increase sa, propulsion, absorption/secretion, simple columnar, ciliated a. i. Example: goblet (mucus) cells: pseudostratified columnar, all cells attached to the basement membrane so not truly stratified, undifferentiated cells don"t reach apical layer c. In trachea and upper repertory tract: ciliated propulsion. In largest ducts of glands: stratified columnar a. In urethra and some in largest ducts of glands: transitional a. In urinary bladder: apical cells change shape when tissue stretches. Fibrocytes: maintain the matric: loose ct (lots of ground substance) i. Areolar: gel-like matrix, lots of interstitial fluid, adjoins all epithelia basal side, has all 3 fiber types, defense cells, fat cells. In hypodermis: energy storage, protection, isolation iii. Reticular ct: only reticular fibers, only in lymphoid structures (immune system, labyrinth used by defense cells, dense ct (lots of collagen fibers) i.
