what is an epithelia
tissue that covers or lines surfaces, cavities, and tubules
where are glands derived from
epithelial tissue
what are the 5 mentioned functions if epithelia
protection, absorption, filtration, secretion, and sense reception
what are the 6 unique characteristics of epithelial tissue
-cellularity -special contacts -polarity
-supported by CT -avascular but innervated
-high regeneration capacity
what two things classify a type of epithelia
cell shape of the apical layer and the amount of layers
what is the function of simple squamous epithelia
diffusion, filtration, and secretion
what is the function of simple cuboidal/columnar epithelia
absorption and secretion
what is the function of any stratified epithelium
protection
what structure makes a multicellular gland exocrine or endocrine
whether it has a duct or not
what are the 4 kinds of lateral side cell junctions
gap junctions, tight junctions, adherence junctions, and desmosomes
which protein junction prevents molecules from passing through the paracellular space
tight junctions
