Explanation:

1. Stage fright before a performance is an emotional/physiological response regulated by the nervous system, so the statement is true.
2. The nervous system consists of the brain, spinal cord, and nerves; "spine" refers to the bony structure, not part of the nervous system itself.
3. The peripheral nervous system is made up of nerves that connect the central nervous system (brain/spinal cord) to the rest of the body.
4. Nerves act like wires, transmitting signals between body parts and the central nervous system.
5. Neurons are specialized cells that transmit nerve impulses.
6. Neurons communicate with one another via electrical and chemical signals, so this is true.
7. Motor nerves control voluntary muscle movements; closing your eyes is a voluntary motor action.
8. Sensory nerves detect stimuli; a bug bite itching is a sensory response to irritation.
9. Heartbeat is an involuntary function controlled by the autonomic nervous system, not somatic (voluntary) nerves, so the statement is false.
10. Autonomic controls involuntary functions, while somatic controls voluntary functions, analogous to automatic vs voluntary actions.
