Detailed explanation-1: -Nerves have large “capillary” containers that are significantly larger than any other capillary system. This system has been likened to a “living container.” These capillaries not only transport the blood but store the blood at the same time.
Detailed explanation-2: -The nervous system is the body’s inner communication system. It’s made up of the body’s many nerve cells. The nerve cells take in information through the body’s senses: touch, taste, smell, sight, and sound. The brain interprets these sensory cues to understand what’s going on outside and inside the body.
Detailed explanation-3: -Beyond the supply of blood, the CNS filters that blood into cerebrospinal fluid (CSF), which is then circulated through the cavities of the brain and spinal cord called ventricles.
Detailed explanation-4: -Neuronal cell body of a sensory afferent is not part of the central nervous system.
