GMS 6520 (Med Pharm I - Nervous): PROBLEM SET 2
QUESTIONS
A patient that is prone to diarrhea would likely have increased
______ tone.
sympathetic
parasympathetic Correct Answers parasympathetic
How many molecules of acetylcholine is a nAChR capable of
binding?
1

5 Correct Answers 2
If the ACh binding sites of an AChR at the autonomic ganglia
are always associated with α subunits, what is the purpose of
having other types of subunits (i.e. beta and gamma)? On the
surface they would seem to be unimportant "filler." Correct
Answers The other subunits make up the functional and
structural portion of the receptor. Different combinations of
subunits supplies selectivity between the different types of ACh
receptors (i.e., different responses to acetycholine in different
receptors across the body).
Increased parasympathetic tone would be expected to have what
effect on arterioles?
