The cranial cavity and the vertebral canal contain the spinal cord
Vertebrae is the synonym of spine. Inside the spine, there will be spinal cord protected by the nearby bone. Spinal cord will divided into many smaller cords after leaving the spine and spread through the body to carry signal from/to the brain. Without the spinal cord, the brain will not be able to reach and control the body.
The cranial cavity and vertebral canal contain the brain and spinal cord, respectively, which make up the central nervous system and are protected by cerebrospinal fluid.
The cranial cavity and the vertebral canal contain the central nervous system, which includes the brain and the spinal cord respectively. 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.
