Histology Flashcards
1
Q
Basement Membrane
A
Separates the epithelium from underlying connective tissue
2
Q
Epithelia classification
A
Simple - one layer
Stratified - two layers
Pseudostratified - one layer but not all cells reach apical region. Look for cilia as a giveaway
Squamous
Cuboidal
Columnar
Keratinized vs nonkeratinized (presence if nucleus)
Transitional - dome shaped, or flattened (depends if relaxed or stretched, example is bladder tissue)
3
Q
Zonula occludens
A
Tight junction - in between cells on apical side, prevents things from leaving lumen and entering intercellular space
4
Q
Fascia occludens
A
Ribbonlike area of fusion between transmembrane proteins on adjacent endothelial cells
5
Q
Zonula adherens
A
Belt desmosome or intermediate junction
6
Q
Desmosome
A
Adhesive site between epithelial cells
