Question

Quizplus · Accepted Answer

Neurons are the main components of the central nervous system, while nerves are the main components of the peripheral nervous system. Axons and dendrites are both types of neurons and are found in both the central and peripheral nervous systems. Myelin sheaths are a type of insulation found on axons in both systems, and neurotransmitters are chemicals used by neurons in both systems to communicate. Hormones are not directly related to either the central or peripheral nervous system, as they are produced by the endocrine system.
