cholinergic receptors

Cholinergic receptors are a type of protein found on the surface of certain cells in the body that respond to the neurotransmitter acetylcholine. They play a crucial role in transmitting messages between nerve cells, influencing various functions such as muscle movement, heart rate, and memory. There are two main types: nicotinic receptors, which are involved in muscle activation and some brain functions, and muscarinic receptors, which primarily affect the heart and other organs. These receptors are essential for many bodily processes and are a key focus in understanding diseases and developing treatments, particularly in areas like neurology and cardiology.
