Body Cavities There are two sets of internal body cavities called the dorsal and ventral body cavities. These cavities are closed to the outside. 1-Dorsal Body Cavity Which protects the fragile nervous system organs has two subdivisions. The cranial cavity, in the skull, encases the brain. The vertebral, or spinal, cavity, which runs within the bony vertebral column, encloses the delicate spinal cord. The cranial and
2- Ventral Body Cavity The more anterior and larger of the closed body cavities is the ventral body cavity .It has two major subdivisions, the thoracic and the abdominopelvic cavities. It houses internal organs collectively called the viscera . They are separated by the diaphragm, a dome-shaped muscle important in breathing. The abdominopelvic cavity, as its name suggests, has two parts not physically separated by a muscular or membrane wall.
Body Cavities and Membranes Dorsal body cavity Cavity subdivided into the cranial cavity and the vertebral cavity. Cranial cavity houses the brain. Vertebral cavity runs through the vertebral column and encloses the spinal cord
