PATHOLOGY

Detailed explanation-1: -The brain and spinal cord are protected from damage by a clear liquid called cerebrospinal fluid, 3 layers of membranes called the meninges, and the hard bones of the skull and backbone.

Detailed explanation-2: -The central nervous system is better protected than any other system or organ in the body. Its main line of defense is the bones of the skull and spinal column, which create a hard physical barrier to injury.

Detailed explanation-3: -The purpose of the spinal cord is to send motor commands from the brain to the peripheral body as well as to relay sensory information from the sensory organs to the brain. Spinal cord protection is by bone, meninges, and cerebrospinal fluids.
