Explanation:

Nervous system is composed of two major parts:

1. central nervous system

2. peripheral nervous system.

Central nervous system or CNS, is responsible for the integration of received information and also coordinates the various activities of all the body parts in the bilaterally symmetric animals. It contains the brain, the spinal cord and the optic nerve.

Whereas, peripheral nervous system or PNS, consists of all the nerves and the ganglia present outside the brain and the spinal cord. Therefore, the spinal nerves, radial or ulnar nerves and dorsal root ganglia are a part of the peripheral nervous system.

Therefore, the brain, the spinal cord and the optic nerve are a part of the Central Nervous System.
