Detailed explanation-1: -The dorsal body cavity includes the cranial cavity, enclosed by the skull and contains the brain, and the spinal cavity, enclosed by the spine, and contains the spinal cord. The ventral body cavity includes the thoracic cavity, enclosed by the ribcage and contains the lungs and heart; and the abdominopelvic cavity.
Detailed explanation-2: -The dorsal body cavity is located along the dorsal (posterior) surface of the human body, where it is subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord. The two cavities are continuous with one another.
Detailed explanation-3: -The vertebral cavity encloses the spinal cord and is divided into five regions: the cervical, thoracic, and lumbar regions, and the sacrum and coccyx bones. The dorsal cavity is lined by the meninges, which encloses and protects the brain and spinal cord.
Detailed explanation-4: -The cranial cavity fills most of the upper part of the skull and contains the brain. The spinal cavity is a very long, narrow cavity inside the vertebral column. It runs the length of the trunk and contains the spinal cord.
