Epithelial Tissue
Sheet of cells that covers a body surface or lines a body cavity
Microvilli
Finger like extensions of the plasma membrane. Increase the exposed surface area
Cilia
Tiny hair like projections that propel substances along their free (apical) surface
Basal Lamina
Noncellular sheet-largely glycoproteins- some fne collegan fiber. Selective filter for diffusing molecules from underlying CT.
Reticular Lamina
Extra cellular material containing a fine network of collagen protein that "belongs" to the underlying CT.
Basement Membrane
Basal Lamina plus Reticular Lamina for basement membrane. (reinforces epithelial sheet from tearing)
Unicellular Exocrine Glands
Mucus cells and goblet cells. Sprinkled in the lining of intestinal & respiratory tract. Produce mucus
Multicellular Exocrine Glands
Simple-unbranched duct
Compound-branched duct
Tubular-cells form tubes
Alveolar-small sacs
TubularAlveolar-have both
Multicellular Exocrine Glands

Modes of secretion
Mecrocine glands- secrete as they produce (Sweat, salivary)
Holocrine glands-built up product until they rupture (sebaceous)
Polarity =
Apical Surface
Basal Surface
Apical = upper free surface exposed to body exterior or internal organ.
Basal= see basal lamina
