Updated On: Jun 16, 2025
- nicotinic
- muscarinic
- alpha-1
- beta-2
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Atropine is a competitive antagonist of muscarinic acetylcholine receptors. It inhibits parasympathetic nerve impulses by selectively blocking the binding of acetylcholine to muscarinic receptors. It does not act on nicotinic, alpha-1, or beta-2 receptors.
