“The mesothelium is a membrane that covers and protects most of the internal organs of the body.”
“In medical terms, it is a cancer formed in the mesothelium, which is a direct consequence of prolonged asbestos exposure.”
“Mesothelioma mainly affects the mesothelium which is a protective lining covering all internal organs of the body.”
“It is also widely accepted that asbestos fibers can be associated with three types of diseases: asbestosis: a lung fibrosis resulting from long-term, high level exposures to airborne fibers; lung cancer: usually resulting from long-term high level exposures and often correlated with asbestosis; mesothelioma: a rare form of cancer of the lining (mesothelium) of the thoracic and abdominal cavities.”
“The meningeal or supporting layer is lined on its inner surface by a layer of nucleated flattened mesothelium, similar to that found on serous membranes.”
“Its internal surface is smooth and covered by a layer of mesothelium.”
“Its outer surface is covered with a layer of low cuboidal mesothelium.”
“The inner surface and the trabeculæ are likewise covered by a somewhat low type of cuboidal mesothelium which in places are flattened to a pavement type.”
“Those portions of the alimentary canal covered by peritoneum, have in addition a subserous lymphatic capillary plexus beneath the mesothelium.”
“Beneath the mesothelium lining of the pleural, peritoneal and pericardial cavities are rich plexuses; they do not open into these cavities.”
