Muscarinic receptors

Muscarinic receptors are a type of protein found on the surface of certain cells in the body. They respond to a neurotransmitter called acetylcholine, which plays a crucial role in communication between nerve cells. These receptors are part of the parasympathetic nervous system, often associated with 'rest and digest' functions, such as slowing the heart rate, increasing saliva production, and promoting digestion. They are important for various bodily processes, including heart function, gland secretion, and muscle contraction, contributing to overall physiological balance and response to the environment.
