|
|
two categories of epithelial tissue
|
membranous and glandular
|
|

membranous epithelial
|
|
|
3 classes of tissue according to cell shape
|
squamous epithelial-flattened, almost 2d
cuboidal epithelial-like cube columnar epithelial-elongated columns |
|
|
classification of tissues according to number of layers
|
simple ep.-for transport, single layer and flat

does membranous epithelial tissue have blood supply? A nerve supply?
|
no. yes
