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.rom Wikipedia, the free encyclopedia.

Body cavities are areas in the body that contain our internal organs. The dorsal and ventral cavities are the two main cavities. The dorsal cavity is on the posterior (back side) of the body and contains the cranial cavity and spinal cavity.In human anatomy, dorsal, caudal and posterior mean the same thing. The ventral cavity is on the front (anterior) of the body and is divided into the thoracic cavity (chest) and abdominopelvic cavity. Anterior means toward the front (chest side) of the body, posterior means toward the back. 2  Medial and Lateral. 3  Medial means toward the midline of the body, lateral means away from the midline. 4  Ipsilateral means on the same sideâthe left arm is ipsilateral (on the same side) to the left leg.
