Question

Quizplus · Accepted Answer

The peripheral nervous system consists of nerve fibres that carry information between the CNS (central nervous system) and other parts of the body, including sensory information from the senses, as well as motor instructions to the muscles and glands. It includes 31 pairs of spinal nerves and 12 pairs of cranial nerves. The fibres in the peripheral nervous system are myelinated either by Schwann cells or by oligodendrocytes, depending on whether they are part of the somatic or autonomic nervous system. The peripheral nervous system includes both sensory and motor nerve fibres.
