Final answer:
C) Norepinephrine. The sympathetic division primarily uses norepinephrine to excite target organs. The sympathetic nervous system is often associated with the "fight or flight" response, and norepinephrine, along with epinephrine (adrenaline) released from the adrenal glands.
Step-by-step explanation:
The primary neurotransmitter used by the sympathetic division to excite target organs is norepinephrine. Norepinephrine is released by postganglionic sympathetic fibers and binds to adrenergic receptors on target cells. In contrast, the parasympathetic division primarily releases acetylcholine on target organs.
The sympathetic division of the autonomic nervous system primarily uses norepinephrine as its neurotransmitter to excite target organs. The sympathetic nervous system is often associated with the "fight or flight" response, and norepinephrine, along with epinephrine (adrenaline) released from the adrenal glands, plays a key role in mediating the physiological responses associated with this stress response. The sympathetic nervous system is often associated with the "fight or flight" response, and norepinephrine, along with epinephrine (adrenaline) released from the adrenal glands, Norepinephrine acts on adrenergic receptors in various target tissues, such as the heart and blood vessels, to prepare the body for increased physical activity and heightened alertness.
