Anatomy and Physiology Chapter 4
Questions and Answers (2026)
Cell Junctions - correct answer: Contact points between the plasma membranes of tissue cells
Types of Cell junctions (5) - correct answer: Tight Junctions, Adherents Junctions, Desmosomes,
Hydrosomes, and Gap Junctions
Gap Junction - correct answer: Connexons connect neighboring cells to rapidly move energy or
electricity to other cells. "Tunnels"
Tissue - correct answer: Group of similar cells that predoom specific functions
Types of tissues - correct answer: Epithelial, Connective, Nervous, and muscular
Epithelium Tissue - correct 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 - correct answer: Surfaces faces body surface- internally or externally.
Basal Surface - correct answer: Opposite of Apical surface- adheres to basement membrane
Basement membrane - correct answer: Basal lamina and reticular lamina
Vascular/Avascular - correct answer: Not own nerve supply/Own nerve supply
, Epithelial classification - correct answer: Number of layers(Simple Vs. Stratified) and shape
(Squamous Vs. Cuboidal Vs. Columnar)
Simple - correct answer: Single layer of cells. Allow for diffusion, osmosis, secretion, excretion,
absorption, filtration.
Stratified - correct answer: For protection (skin), multiple layers on top of each other
Pseudostratified - correct answer: Pseudo-false. Looks like multiple layers but all cells are
touching basal surface.
Squamous - correct answer: Thin and flat
Cuboidal - correct answer: Cube shaped
Columnar - correct answer: Cells in columns
Transitional - correct answer: Cells appear one way, but change shape under different conditions
Glandular Epithelium - correct answer: Cells lie in clusters deep to covering and lining
epithelium, produce secretions. (Glands)
Endocrine Glands - correct answer: Secretions(Hormones) enter the interstitial fluid and diffuses
directly into blood stream with out flowing into a duct
Exocrine Glands - correct 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. tubularian.
