PERITHELIAL CELL Meaning and
Definition
-
Perithelial cell refers to a specialized type of cell found in the body, specifically lining the outer surface of organs or body cavities. These cells play a crucial role in providing protection and support to the organs they surround.
Perithelial cells are flat and tightly packed epithelial cells that form a continuous layer, acting as a barrier between the organ or cavity and the surrounding tissues. They are present in many different organs and structures, including the peritoneum (lining of the abdominal cavity), pleura (lining of the lungs), and pericardium (lining of the heart).
The main function of perithelial cells is to maintain the integrity of the organ or cavity they enclose. They provide a physical barrier that prevents the passage of harmful substances or infectious agents, ensuring optimal organ function and protection from potential damage. Perithelial cells also secrete mucus, which helps to lubricate and protect the organ surface against friction.
Additionally, perithelial cells play a role in regulating the transport of molecules across the organ or cavity. They can selectively absorb or secrete substances based on the specific needs of the organ or body system. This ability assists in maintaining the appropriate balance of fluids and electrolytes in the body.
Overall, perithelial cells are essential components of various organs and body cavities, supporting their proper functioning, protecting them from harm, and aiding in the maintenance of optimal physiological conditions.

Etymology of PERITHELIAL CELL
The word "perithelial cell" is a compound term composed of two parts: "peri-" and "thelial cell".
1. "Peri-" is a prefix derived from Greek meaning "around" or "surrounding". It is commonly used in medical terminology to denote something located or occurring around or near a specific structure.
2. "Thelial" is derived from the Greek word "thēle", which means "nipple" or "teat". In biology, it refers to cells or tissues that line a body cavity or surface, such as the epithelial cells that line the organs.
Therefore, the term "perithelial cell" refers to a type of cell located or occurring around or near epithelial tissue or cells.
