What is the function of the spine cavity?
The main purpose of the spinal cavity is similar to that of the skull cavity. The spinal cord is very sensitive to damage and must be cushioned. In addition, separation provides some protection against exposure to bacteria and viruses.
What’s in the Center Channel?
The central canal is part of the cerebrospinal fluid (CSF) cavity system it covers cerebral ventricle, Sylvius aqueduct and fourth ventricle (Pictures 3- 4) [2]. It is located in the gray commissure which (along with the front white commissure) connects the two parts of the spinal cord.
Is the nerve canal the same as the central canal?
The nerve canal is the cavity or cavity system in the embryo of the vertebrae that forms the ventricles of the brain and the central canal of the spinal cord. … The neural network associated with the neural canal is more ubiquitous along the anterior border of the canal.
