Question

A drug that affects both divisions of the autonomic system is going to bind to, or block, which type of neurotransmitter receptor?

A.) nicotinic
B.) muscarinic
C.) α-adrenergic
D.) β-adrenergic

Answer 1

A drug that affects both divisions of the autonomic system is going to bind to muscarinic receptors.

Step-by-step explanation:

The drug that affects both divisions of the autonomic system is going to bind to muscarinic receptors (B).

The cholinergic system has two types of receptors: nicotinic receptors and muscarinic receptors. Nicotine binds to the nicotinic receptor, while muscarine binds to the muscarinic receptor. Since the drug affects both divisions of the autonomic system, it is likely to bind to muscarinic receptors which play a role in both parasympathetic and sympathetic systems.
