What is the main difference between the CNS and PNS?
The CNS consists of the brain and spinal cord, while the PNS includes all other nervous system tissue. All sensory receptors, sensory neurons and motor neurons are part of the PNS.
What do CNS and PNS have in common?
The CNS includes the brain and spinal cord. The brain is the body’s “control center.” The CNS has various centers located within it that carry out the sensory, motor and integration of data. … The PNS is a vast network of spinal and cranial nerves that are linked to the brain and the spinal cord.
What is the relationship between CNS and PNS?
If the central nervous system is the command centre of the body, the peripheral nervous system (PNS) represents the front line. The PNS links the CNS to the body’s sense receptors, muscles, and glands.
