Mucous Membrane


A membrane (also called Mucosa or Mucosal tissue) that comprises the lining of various body organs, including those exposed to the external environment.

A mucous membrane is thinner and less keratinized than normal skin, and allows absorption or secretion of various substances across it. The glans and inner foreskin of the penis are covered in mucous membranes, which is continuous with the outer foreskin.
