Question

Quizplus · Accepted Answer

The peripheral nervous system consists of nerve fibres that carry information between the central nervous system and other parts of the body, including sensory and motor fibres. Option A is partly correct, as it lists the spinal and cranial nerves, but it does not encompass the entirety of the peripheral nervous system. Option C is incorrect, as myelination in the peripheral nervous system is carried out by Schwann cells, not oligodendrocytes. Option D is incorrect, as the peripheral nervous system includes both sensory and motor fibres.
