Nerve cells transmit impulses through which parts of the nervous system?

Nerve cells transmit impulses through which parts of the nervous system?

• A. Central and peripheral nervous system
• B. Peripheral nervous system
• C. Central nervous system
• D. Brain only

Answer: (A)

Nerve impulses use a complete network: signals come into the central nervous system (the brain and spinal cord), are processed there, and then commands travel out via the peripheral nervous system to muscles and glands. The brain and spinal cord coordinate and interpret information, while the peripheral nerves carry signals to and from the rest of the body. Because transmission involves both processing and distribution through nerves outside the brain and spinal cord, both systems are involved, not just the brain or just one part. So the whole central and peripheral nervous system best explains how impulses are transmitted.
