Question

Quizplus · Accepted Answer

The central nervous system (CNS) of vertebrate animals consists of only the brain and spinal cord. Choice A (the brain) and B (the spinal cord) are components of the CNS. Choice C (all nerves in the body) is incorrect because while the CNS is responsible for processing and interpreting information from all nerves in the body, it is not comprised of all nerves in the body. Choice D (nerves originating at sensory receptors) is incorrect because while sensory nerves do transmit information to the CNS, they are not part of the CNS itself.
