Mesothelium vs. Endothelium

Mesotheliumnoun

(biology) A membrane of flat epithelial cells that lines the body cavity of embryos and forms the squamous cells of the peritoneum, pericardium, and pleura

Mesotheliumnoun

Epithelial mesoderm; a layer of cuboidal epithelium cells, formed from a portion of the mesoderm during the differetiation of the germ layers. It constitutes the boundary of the cŒlum.

Mesotheliumnoun

epithelium originating in the embryonic mesoderm; lines the primordial body cavity

Mesothelium

The mesothelium is a membrane composed of simple squamous epithelial cells of mesodermal origin, 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). Mesothelial tissue also surrounds the male testis (as the tunica vaginalis) and occasionally the spermatic cord (in a patent processus vaginalis).

Endotheliumnoun

(anatomy) A thin layer of flat epithelial cells that lines the heart, serous cavities, lymph vessels, and blood vessels.

Endotheliumnoun

The thin epithelium lining the blood vessels, lymphatics, and serous cavities. See Epithelium.

Endotheliumnoun

an epithelium of mesoblastic origin; a thin layer of flattened cells that lines the inside of some body cavities

Endothelium

Endothelium is a single layer of squamous endothelial cells that line the interior surface of blood vessels, and lymphatic vessels. The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.
