The parietal cell membrane is dynamic; the numbers of canaliculi rise and fall according to secretory need. This is accomplished by the fusion of canalicular precursors, or tubulovesicles, with the membrane to increase surface area, and the reciprocal endocytosis of the canaliculi (reforming the tubulovesicles) to decrease it.

The serous membrane (or serosa) is a smooth tissue membrane of mesothelium lining the contents and inner walls of body cavities, which secrete serous fluid to allow lubricated sliding movements between opposing surfaces. The serous membrane that covers internal organs is called visceral, while the one that covers the cavity wall is called parietal.
The parietal pleura (from Latin: paries, lit. 'wall') lines the inside of the thoracic cavity which is set apart from the thoracic wall by the endothoracic fascia. The Parietal includes the inner surface of the rib cage and the upper surface of the diaphragm, as well as the side surfaces of the mediastinum, from which it separates the pleural ...
The serous membrane that covers the surface of the lung is the visceral pleura and is separated from the outer membrane, the parietal pleura, by just the film of pleural fluid in the pleural cavity. The visceral pleura follows the fissures of the lung and the root of the lung structures.
The peritoneal cavity is a potential space located between the two layers of the peritoneum—the parietal peritoneum, the serous membrane that lines the abdominal wall, and visceral peritoneum, which surrounds the internal organs. [1]
The tunica vaginalis, the serous membrane covering the male testis, is derived from the vaginal process, an outpouching of the parietal peritoneum. The inner layer, the visceral peritoneum, is wrapped around the visceral organs, located inside the intraperitoneal space for protection. It is thinner than the parietal peritoneum.
Superior parietal lobule, bounded in front by the upper part of the postcentral sulcus; Parietal branch of superficial temporal artery, curves upward and backward on the side of the head; Parietal-temporal-occipital (PTO), includes portions of the parietal, temporal, and occipital lobes; Parietal bone, of the skull Parietal foramen (disambiguation)
This fascial layer is the outermost membrane of the thoracic cavity. The endothoracic fascia contains variable amounts of fat. It becomes more fibrous over the apices of the lungs as the suprapleural membrane. It separates the internal thoracic artery from the parietal pleura.
