Answer:
In simple words, Sensory as well as motor nerves are indeed the two main forms of muscles. Sensory nerves transmit knowledge to the brain as well as spinal cord like touch, temperature, even pain. Motor nerves carry brain impulses back to the muscles, allowing them to contract spontaneously or compulsively.
The central nervous system of your body is made up of the brain and spinal cord. The brain serves as the human body operations centre and the spinal cord serves as a conduit for signals transmitted from the brain to the body as well as from the cytoplasm to the nucleus.
