Name the two components of peripheral nervous system.
Name the two components of peripheral nervous system.
Official answer
The two components of the peripheral nervous system are:
- Cranial nerves (which arise from the brain)
- Spinal nerves (which arise from the spinal cord)
Marking scheme
- 1.0.5 marks
- 2.0.5 marks
Hint
Think about the nerves that connect the brain and the spinal cord to the rest of the body.
Quick oral answer
The peripheral nervous system consists of cranial nerves arising from the brain and spinal nerves arising from the spinal cord.
Common mistakes
- 1.Confusing the peripheral nervous system with the central nervous system (brain and spinal cord).
- 2.Listing sensory and motor neurons instead of the anatomical nerve components (cranial and spinal nerves).
Analysis and explanation
According to the NCERT text, the central nervous system (CNS) consists of the brain and spinal cord. The communication between the CNS and the rest of the body is facilitated by the peripheral nervous system (PNS). The PNS is composed of cranial nerves that originate from the brain and spinal nerves that originate from the spinal cord.
Interesting facts
There are 12 pairs of cranial nerves and 31 pairs of spinal nerves in the human body that form the network of the peripheral nervous system.
