59
Cells that make up bone tissue ?
Osteocytes &osteoclasts
60
General function is to prevent leakage of transported solutes and water and seals the paracellular pathway
Tight junction
61
Connects the cytoplasm of two cells, which allows molecules, ions, and electrical impulses to directly pass through
Gap Junction
62
- Protein complexes that occur at cell to cell junctions, in epithelial and endothelial tissue.
- more basal than right junctions
Adherents junctions
63
Single layer of flattened cells;
Simple squamous epithelial
64
This epithelium is often associated with absorption, secretion, or excretion of waste matter..
Simple cuboidal
65
Single layer of cells that are taller than they are wide
Single columnar epithelium
66
Appears to be stratified because the nuclei of the epithelial cells are at different levels.
Pseudostratified
67
Has multiple layers of cells becoming flattened as they move from the basal layer to the apical layers.
