What is the purpose of the myelin sheath?

The peripheral nervous system

• connects the brain to the spinal cord.

• calms the body after an emergency.

Opiate drugs such as morphine are classified as what?

• Excitatory neurotransmitters, because they activate pain-control mechanisms

• Antagonists, because they block neurotransmitter receptors for pain

• Agonists, because they mimic other neurotransmitters' pain-diminishing effects

• Sympathetic nervous system agents, because they prepare the body for a challenge
