Epithelial Tissue Flashcards
A protective, continuous sheet of compactly packed cells
epithelium (plural= epithelia)
Characteristics
Cellularity, Polarity, Attachment, Vascularity and Innervation, Regeneration
Tight connection between cells to avoid leakage
Tight junctions
Link cytoskeleton of the adjacent cells, and link proteins in cell membrane
Adherens junctions
Cell-to-cell connection that allows exchange of organic material
Gap junction
