f. brain, the 12 pairs of cranial nerves, the spinal cord, & the 31 pairs of spinal nerves

Answer 1

Answer

Option E) The 12 pairs of cranial nerves & the 31 pairs of spinal nerves

• Nervous system is divides into central and peripheral divisions.
• Brain and spinal cord are the part of central nervous system.
• Peripheral nervous system comprises of all the nervous tissue outside brain and spinal cord.
