What are the components of the peripheral nervous system? (A) The brain and spinal cord. (B) The brain and cranial nerves. (C) The spine and the spinal nerves. (D) The nerves outside of the brain and spinal cord.

This question asks us to recall what we know about the structure and function of the human nervous system. To efficiently collect, process, and respond to information, the nervous system has a highly organized structure. It can be divided into subdivisions, each with their own specific structural and functional characteristics. The first division of the human nervous system splits the network into two subdivisions: the central nervous system and the peripheral nervous system.

The central nervous system consists of two main components: the brain and the spinal cord. A major function of the brain is to control complex functions like thinking, processing, and interpreting sensory information, as well as coordinating a motor response. The spinal cord is the information superhighway of the central nervous system. Its major function is to relay messages between the brain and the body.

The peripheral nervous system refers to all of the nerves outside of the brain and spinal cord, which comprise the central nervous system. The primary function of the peripheral nervous system is to transmit information towards and away from the central nervous system. The peripheral nervous system carries sensory information from internal and external environments towards the central nervous system for processing. After processing in the brain, the peripheral nervous system carries the motor responses from the brain to the organs, muscles, and glands.

Now, we know that the central nervous system is composed of the brain and the spinal cord, while the peripheral nervous system is made up of all of the nerves outside of the central nervous system. With this information, we are now able to correctly answer our question. The main components of the peripheral nervous system are the nerves outside of the brain and spinal cord.
