|
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 |
