Vertebrate animals have two major body cavities: the dorsal cavity and the ventral cavity. The dorsal cavity contains the cranial cavity, which fills most of the upper part of the skull and houses the brain, and the spinal cavity, also known as the vertebral canal, which is a long, narrow cavity inside the vertebral column that contains the spinal cord. These two cavities are continuous with one another, forming a protective environment for the central nervous system complemented by cerebrospinal fluid, which acts as a cushion and circulates through both cavities and their contained structures.
