Mucosa
Mucosa (mew-co-sa)
The Mucosa or mucous membrane is a type of tissue that lines various cavities in the body and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is often associated with secretory glands that are either directly or indirectly linked to it.
Etymology
The term "mucosa" is derived from the Latin word "mucus," which means "slime" or "slippery secretion." This is in reference to the thick, viscous secretions that are often produced by mucosal tissues.
Function
The primary function of the mucosa is to provide a barrier against the external environment. This includes protection from mechanical damage, chemical damage, and infection. In addition, the mucosa also serves as a site for absorption and secretion.
Types of Mucosa
There are several types of mucosa in the human body, including:
- Respiratory mucosa: This lines the respiratory tract, from the nose to the lungs.
- Gastrointestinal mucosa: This lines the gastrointestinal tract, from the mouth to the anus.
- Urogenital mucosa: This lines the urinary tract and the reproductive system.
