| dermatome | mapping of body surface to reveal connection between peripheral nerve and spinal nerve |
| autonomic nervous system | consists of motor neurons that conduct impulses to heart, smooth muscle, and glands |
| sympathetic nervous system | part of ANS involved in emergency response |
| parasympathetic nervous system | part of ANS involved in ordinary "normal" response |
| adrenalin | neurotransmitter produced by sympathetic postganglionic nerve |
| medulla oblongata | part of brainstem that influences heartbeat |
| pons | part of brainstem that influences respiration |
