mesoteliaalisen

Mesoteliaalinen refers to the mesothelium, a serous membrane that forms the lining of several body cavities, including the pericardial, pleural, and peritoneal cavities. It also covers the organs within these cavities. The mesothelium is a single layer of flat, squamous cells called mesothelial cells. These cells are supported by a thin basement membrane and a layer of connective tissue. The primary function of the mesothelium is to provide a smooth, frictionless surface that allows organs to move freely within the body cavities. It also plays a role in lubrication, absorption, and secretion. A thin layer of serous fluid is secreted by the mesothelial cells, which further reduces friction between the surfaces.

Diseases related to the mesothelium are often referred to as mesothelial diseases. The most well-known mesothelial tumor is mesothelioma, a type of cancer that arises from the mesothelial cells. Mesothelioma is strongly linked to exposure to asbestos fibers, which can become lodged in the mesothelium and cause chronic inflammation and genetic mutations leading to cancer. Other mesothelial conditions can include benign tumors and inflammatory conditions. The study of the mesothelium and its associated pathologies falls under the purview of pathology and oncology.
