The Autonomic Nervous System - Part 2
The autonomic nervous system coordinates many bodily functions that are not generally under conscious control (i.e., involuntary functions). For example, the autonomic nervous system regulates the function of cardiac muscle, smooth muscle, and various glandular structures (e.g., sweat glands, salivary glands, and some endocrine glands). Test your basic knowledge of the autonomic nervous system by taking this simple quiz.
(1)   These cells of the adrenal medulla are responsible for secreting epinephrine, norepinephrine, and dopamine (very small amount) into the bloodstream.

(2)   This subcompartment of the adrenal glands is responsible for secreting epinephrine, norepinephrine, and dopamine.
(3)   In typical neurons, neurotransmitter molecules are released only from the axon terminal. In contrast, in autonomic motor neurons, neurotransmitters are released from axonal regions known as:

(4)   This neurotransmitter is released from the axon terminals of pre-ganglionic parasympathetic fibers:
(5)   Post-ganglionic sympathetic neurons release the following neurotransmitter(s):
(6)   The neurotransmitter that is most commonly released from post-ganglionic sympathetic neurons is:
