Flashcards in Test 1 ch 4 Deck (10):
1
What are the 4 tissue types
epithelial, connective, muscle, and neural
2
4 functions of epithelial tissue
physical protection, control permeability, provide sensation, produce specialized secretions
3
gap junctions
connects cells using channel proteins that allow for rapid intercellular communication
4
hemidesmosomes
attaches a cell to extracellular filaments in the basement membrane for stabilization
5
simple epithelium
one layer of cells that cover the basement membrane
6
stratified epithelium
several layers of cells cover the basement membrane
7
squamous epithelium
thin, flat, irregular shape (jigsaw puzzle)
8
simple squamous epithelium
reduce friction, controls vessel permeability, performs absorption and secretion
found: lines ventral body cavities, vessels
9
stratified squamous epithelium
provide physical protection against abrasion, pathogens, and chemical attack
found: skin surface, lining of mouth, throat, esophagus, rectum, anus, and vagina
