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

10

cuboidal epithelia

nuclei are near the center of each cell and the distance between adjacent nuclei is roughly equal to the height of the epithelium.
