Compound epithelium consists
of more then one layer of cells. Stratified epithelium forms the epidermal
layers of the skin.
It also lines the
mouth, pharynx, oesophagus, the lower part of the urethra, the anal canal and
the vagina, and covers the surface of the cornea. In these areas it does not
become cornified.
The outer layers of
cells near the urface comprise the horny layer of the skin; these cell are flattened
and resemble scales. The deepest layer of cells are columnar in shape.these
form the germinative layer and here the cell multiply by karyo-kinesis, pushing
those above them nearer the surface until the superficial ones are cast of.
The cells between
the basal layer and the horny zone are called ‘prickle cells’ they are
connected to each other by fine tendrils which give them a prickly appearance
when examined under the microscope.
