Detailed explanation-1: -The dorsal cavity is a continuous cavity located on the dorsal side of the body. It houses the organs of the upper central nervous system, including the brain and the spinal cord. The meninges is a multi-layered membrane within the dorsal cavity that envelops and protects the brain and spinal cord.
Detailed explanation-2: -Dorsal cavity is one long, continuous cavity located on the back of the body. Also known as the posterior or back portion.
Detailed explanation-3: -The dorsal term has been derived from a Latin word ‘dorsum’ meaning ‘back’. Therefore, it refers to the surface to the back or upper side of an organism. The back side of the body of the human is the dorsal side.
Detailed explanation-4: -In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity (or vertebral cavity) encloses the spinal cord. Just as the brain and spinal cord make up a continuous, uninterrupted structure, the cranial and spinal cavities that house them are also continuous.
