Detailed explanation-1: -The central nervous system is the brain and spinal cord, while the peripheral nervous system consists of everything else. The central nervous system’s responsibilities include receiving, processing, and responding to sensory information.
Detailed explanation-2: -Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.
Detailed explanation-3: -The brain and spinal cord are the organs of the central nervous system. Because they are so vitally important, the brain and spinal cord, located in the dorsal body cavity, are encased in bone for protection.
Detailed explanation-4: -The cranial nerves emerge directly from the brain and brain stem. On the contrary, the spinal nerves emerge from the segments in the spinal cord.
