Sympathetic | nerves of the ANS that originate from the thoracolumar portion of the spinal cord; active when the body is under stress |
Parasympathetic | active when the body is a rest or trying to restore body energy and function |
Acetylcholine (ACH) | neurotransmitter of parasympathetic nerves; stimulates the cholinergic receptor; excitatory neurotransmitter in the basal ganglia |
