Question

2 which of the following does not describe the central nervous system?
sends motor commands to the peripheral nervous system
contains the brain and the spinal cord
receives sensory information from the peripheral nervous system
directly responsible for muscle movement

Explanation:

• The central nervous system (CNS) consists of the brain and spinal cord.
• The CNS receives sensory input from the peripheral nervous system (PNS) and sends motor commands back to the PNS.
• Muscle movement is directly triggered by motor neurons in the PNS, not the CNS itself, so this statement does not describe the CNS.

Answer:

directly responsible for muscle movement
