Pericardium
The endosteum lines the medullary cavity.
The epithelial membrane that lines the walls of the abdominal cavity is called the peritoneum. It consists of two layers: the parietal peritoneum that lines the abdominal wall, and the visceral peritoneum that covers the abdominal organs.
The tissue that lines the walls of the ventral cavity is called the serous membrane or mesothelium. This membrane consists of two layers: the parietal layer which lines the cavity walls, and the visceral layer which covers the organs within the cavity. The serous membrane produces a fluid that reduces friction between internal structures during movement.

The simple squamous epithelium that lines the peritoneal cavity is called mesothelium. It is a single layer of flat cells that help protect and cushion the organs within the peritoneal cavity.

Endosteum
The shiny membrane that lines the inside of the body wall in a dogfish is called the peritoneum. It is a thin serous membrane that surrounds and protects the internal organs within the body cavity.
Serous membrane lines body cavities that do not open to the outside, such as the pleural cavity around the lungs or the peritoneal cavity in the abdomen. These membranes secrete a fluid that helps reduce friction between organs during movement.
The lining on the belly is called the peritoneum. It is a membrane that lines the abdominal cavity and covers the organs within the abdomen.
