What Are Muscarinic Receptors?
Muscarinic receptors are structures found in the membranes of some cells which are responsive to muscarine, among several other chemical compounds. These structures play an important role in the function of the parasympathetic nervous system, which includes glandular tissue, heart muscle, and smooth muscle tissues. One way in which muscarinic receptors function is in the regulation of heart rate, in concert with several other processes in the body.
