Basal Lamina
30
From proteins produce by the epithelial cell
Basal Lamina
31
Filter blood entering the epithelial cells and acts as scaffolding of regenerating epithelial cells
Basal Lamina
32
It is an extracellular matrix - came from proteins produced by epithelial cell
Basal Lamina
33
It is an extracellular matrix - protein:collagen
Basal Lamina
34
also known as basal membrane
Basal Lamina
35
function: mediates physiological interactions (exchange of materials) between the epithelium and underlying connective tissue
Basal Lamina
36
avascular/nonvascular - no blood vessel attached to it
Basal Lamina
37
function: serves as a barrier. limiting invasion of epithelial tissue into underlying tissues
Basal Lamina
38
function: structural support for epithelial repair and regeneration
Basal Lamina

Hemidesmosomes
47
extension of exoskeletion
filaments

Found in high numbers in tissues that are subject to a lot of mechanical forces (muscle tissue)
Desmosomes
53
also known as zonula occludens
Tight Junction
54
Are areas where the membranes of two adjacent cells join together to form a barrier.
Tight Junction
55
Demarcates the apical region from the basolateral region in epithelial cells
Tight Junction
56
Allow the selective diffusion of ions and solutes through the intercellular space
Tight Junction
57
barrier for solutes
Tight Junction
58

found between all cells that are directly touching other cells.
Gap Junction
60
adjacent cells are connected through protein channels
Gap Junction
61
Allows molecules to pass from one cell to the other.
Gap Junction
62
This allows for cell-to-cell communication.
Gap Junction
63
are only found in animal cells;
Gap Junction
64
are connected by channels called p_________________
plasmodesmata
