structures seen with the naked eye
is called the gross
why are epithelia’s avascular
because they are packed too tight .
desmesomes
connect the plasma membranes of adjacent cells
gap junctions
cell linked by tubular channel proteins
basement membrane
cement cells to underlying tissue varies
non living fibers
prevents cells from being torned off
simple cuboidal
look like ice cubes
nuclei aligned single row
found in areas where absorption occurs
simple columbar
single columns
aligned in a row at base cell
absorptive and goblet cells
simple squamous
delicate and thin
flat and smooth
you can find this in animal body in the cavalry area and lungs
stratified squamous
multilayer
protect underlying tissues
found in the oral cavity
and skin has them
stratified cubical epithelium
two layers
