If you have ever taken a human anatomy course, then you might remember learning about the visceral and parietal pleura. Connective tissue supports both membranes. Because of the limited repertoire of tissue response of the pericardium to noxious stimuli, the histologic features of excised pericardium for constrictive pericarditis are generally nonspecific in terms of etiologic diagnosis and most often reflect a spectrum from organizing fibrinous pericarditis to organized fibrocalcific pericarditis. These cells are bound tightly to the underlying connective tissue. The visceral layer (the inner layer that is in contact with … On the other hand, the visceral serous membrane is the inner layer that covers internal organs. There are two layers of the peritoneum: the outer layer, called the parietal peritoneum, is attached to the abdominal wall; the inner layer, the visceral peritoneum, is wrapped around the internal organs that are located inside the intraperitoneal cavity.
