Which of the Following is Most Related to the Postganglionic

Question

Which of the following is most related to the postganglionic sympathetics?
A) Muscarinic receptors
B) ACh
C) Alpha and beta receptor activation
D) Craniosacral outflow

Accepted Answer

Postganglionic sympathetic neurons release norepinephrine, which activates both alpha and beta receptors. Muscarinic receptors are more related to the parasympathetic nervous system, and ACh is released by both sympathetic and parasympathetic postganglionic neurons. Craniosacral outflow refers to the parasympathetic division and is not related to postganglionic sympathetic neurons.
