Cell Junctions - Answer Contact points between the plasma membranes of tissue cells
Types of Cell junctions(5) - Answer Tight Junctions, Adherens Junctions, Desmosomes, Herhidemosomes,
and Gap Junctions
Gap Junction - Answer Connexons connect neighboring cells to rapidly move energy or electricity to
other cells. "Tunnels"
Tissue - Answer Group of similar cells that predom specific functions
Types of tissues - Answer Epithelial, Connective, Nervous, and muscular
Epithelium Tissue - Answer Closely packed cells arranger in continuous sheets that form the outer
covering of body, line body cavities and cover some internal organs. Avascular, and reproduce readily.
Apical Surface - Answer Surfaces faces body surface- internally or externally.
Basal Surface - Answer Opposite of Apical surface- adheres to basement membrane
Basement membrane - Answer Basal lamina and reticular lamina
Vascular/Avascular - Answer Not own nerve supply/Own nerve supply
Epithelial classification - Answer Number of layers(Simple Vs. Stratified) and shape (Squamous Vs.
Cuboidal Vs. Columnar)
, Simple - Answer Single layer of cells. Allow for diffusion, osmosis, secretion, excretion, absorption,
filtration.
Stratified - Answer For protection (skin), multiple layers on top of each other
Pseudostratified - Answer Pseudo-false. Looks like multiple layers but all cells are touching basal surface.
Squamous - Answer Thin and flat
Cuboidal - Answer Cube shaped
Columnar - Answer Cells in columns
Transitional - Answer Cells appear one way, but change shape under different conditions
Glandular Epithelium - Answer Cells lie in clusters deep to covering and lining epithelium, produce
secretions. (Glands)
Endocrine Glands - Answer Secretions(Hormones) enter the interstitial fluid and diffuses directly into
blood stream with out flowing into a duct
Exocrine Glands - Answer Cells produce a secretion into duct system that empties directly on surface of
body or into a cavity (Sweat). Unicellular Vs. Multicellular. Simple Vs. Compound. Tubular Vs. Acinar Vs.
tubuloacinar.
Tubular Vs Acinar Vs Tubuloacinar - Answer Tube like Vs. Round Vs. Both
Merocrine - Answer Most glands, excretes by vesicle- burst off and out of vesicle. Made in Endoplasmic
Reticulum, move to golgi complex and then are released.
