Muscarinic receptor

Muscarinic receptors are a type of protein found on certain cells in your body, especially in your brain, heart, and muscles. They are part of the nervous system's way of sending signals, responding to a chemical called acetylcholine. When acetylcholine binds to these receptors, it triggers various responses, such as reducing heart rate, stimulating saliva production, or affecting brain functions like memory. These receptors play a key role in how your body controls many involuntary functions, and they are important targets for some medications used to treat conditions like glaucoma, asthma, and certain neurological disorders.
