What is the central nervous system
comprised of? (A) The brain and the spinal
cord. (B) The brain and the cranial
nerves. (C) The peripheral nerves in the
external limbs. (D) The spine and the spinal
nerves.
To answer this question, we’ll
review the structure of the human nervous system, paying close attention to the
components of the central nervous system. The human nervous system has three
main functions. They are gathering sensory input,
processing sensory input, and responding to sensory input via motor output. All of these functions are carried
out by the two main parts of the human nervous system.
The two main parts of the human
nervous system are the central nervous system and the peripheral nervous system. The central nervous system is
comprised of the brain and the spinal cord. These two components help to
process and interpret gathered sensory input as well as coordinate an appropriate
motor output response. The peripheral nervous system
refers to all of the nerves outside of the brain and spinal cord. These components help to gather
sensory input and execute the appropriate motor output. With this information, we’re now
ready to answer our question. The central nervous system is
comprised of the brain and the spinal cord.
