The mesothelium is a membrane composed of simple squamous epithelial cells of mesodermal origin, [2] which forms the lining of several body cavities: the pleura (pleural cavity around the lungs), peritoneum (abdominopelvic cavity including the mesentery, omenta, falciform ligament and the perimetrium) and pericardium (around the heart).
For example, the serosa of the uterus is called the perimetrium. Schematic diagram of an organ invaginating into a serous cavity The pericardial cavity (surrounding the heart ), pleural cavity (surrounding the lungs ) and peritoneal cavity (surrounding most organs of the abdomen ) are the three serous cavities within the human body.
Cytology of normal mesothelium, with typical features. Wright's stain. The lateral plate mesoderm splits into the parietal (somatic) and visceral (splanchnic) layers. The formation of these layers starts with the appearance of intercellular cavities. [12] The somatic layer depends upon a continuous layer with mesoderm that covers the amnion.
Pseudostratified columnar epithelium is a type of epithelium that, though comprising only a single layer of cells, has its cell nuclei positioned in a manner suggestive of stratified columnar epithelium.
Specialized squamous epithelium also forms the lining of cavities such as in blood vessels (as endothelium), in the pericardium (as mesothelium), and in other body cavities. Cuboidal Cuboidal epithelial cells have a cube-like shape and appear square in cross-section. The cell nucleus is large, spherical and is in the center of the cell.
A serous membrane is an epithelial membrane composed of mesodermally derived epithelium called the mesothelium that is supported by connective tissue. [2] These membranes line the coelomic cavities of the body, that is, those cavities that do not open to the outside, and they cover the organs located within those cavities.
With three weeks left in the 2024 NFL regular season, it seems likely that at least a few records will be broken. Keep an eye on these marks.
The most notable examples of basement membranes is the glomerular basement membrane of the kidney, by the fusion of the basal lamina from the endothelium of glomerular capillaries and the podocyte basal lamina, [9] and between lung alveoli and pulmonary capillaries, by the fusion of the basal lamina of the lung alveoli and of the basal lamina ...
