1. Compound epithelium consists of many layers of cells.
2. Only the lowermost layer of this tissue is based on the basement membrane.
3. Types of compound epithelium include:
a. Stratified epithelium: Nucleus is present in stratum germinativum (basal layer).
Cells at free surface become flat and lack nucleus called stratum comeum.
Function: Protection e.g. Epidermis of skin, oesophagus, cornea, vagina, rectum.
b. Transitional epithelium:
Structure of transitional epithelium is same like stratified epithelium.
The cells can undergo a change in their shape and structure depending on degree of stretch. Function: Distension of organ e.g. Urinary bladder
