A)It consists of 33 pairs of spinal nerves and 12 pairs of cranial nerves.

C)Its fibres are myelinated by oligodendrocytes.
D)It consists of motor nerve fibres only.

Question

Quizplus · Accepted Answer

The peripheral nervous system is made up of nerve fibres that are located outside of the brain and spinal cord (which make up the central nervous system). These fibres are responsible for carrying information between the CNS and other parts of the body, including sensory information from the senses and motor commands to muscles and organs. Option A is partially correct, but it only gives the number of spinal and cranial nerves without explaining what the PNS is. Option C is incorrect, as oligodendrocytes myelinate axons in the CNS, while Schwann cells myelinate axons in the PNS. Option D is also incorrect, as the PNS contains both sensory and motor fibres.
