Question

question 2 of 10
which statement accurately describes the nervous system?

a. it works just like a battery.

b. it works just like electrical wires.

c. it is electrochemical.

d. it only exists in the brain.

Explanation:

• Option A: A battery stores and provides electrical energy, but the nervous system's function (transmitting signals) is not analogous to a battery's role, so A is incorrect.
• Option B: Electrical wires only conduct electricity, while the nervous system involves chemical processes (neurotransmitters) along with electrical signals, so B is incorrect.
• Option C: The nervous system uses electrochemical processes (electrical impulses and chemical neurotransmitters) to transmit signals, so this is accurate.
• Option D: The nervous system includes the central (brain, spinal cord) and peripheral (nerves throughout the body) systems, so it does not only exist in the brain, making D incorrect.

Answer:

C. It is electrochemical.
