The central nervous system includes
A.The peripheral nerves and spinal cord
B.the brain, brainstem and spinal cord
C.spinal nerves and cranial nerves
D.the cerebrum and cerebellum
B??
It's B
I thought it was D
D is in the CNS, but so is the the rest of the brain, brain stem and spinal cord.
The correct answer is B. The central nervous system includes the brain, brainstem, and spinal cord. To arrive at this conclusion, you need to understand what each option represents and then determine which one accurately describes the central nervous system.
A. The peripheral nerves and spinal cord: This option is incorrect because it only includes the peripheral nerves and spinal cord, leaving out the brain and brainstem.
B. The brain, brainstem, and spinal cord: This option is correct. The brain, brainstem, and spinal cord collectively form the central nervous system.
C. Spinal nerves and cranial nerves: This option is incorrect because it only includes the peripheral nerves, which are part of the peripheral nervous system, not the central nervous system.
D. The cerebrum and cerebellum: This option is incorrect because it only includes specific parts of the brain (cerebrum and cerebellum), not the entire brain and other components of the central nervous system.
Therefore, option B is the correct answer as it includes all the components of the central nervous system.
