Nicotine receptors
Nicotine receptors, specifically nicotinic acetylcholine receptors, are special proteins in the nervous system that respond to the neurotransmitter acetylcholine and the drug nicotine. When activated, they help transmit signals between nerve cells, influencing various bodily functions, including muscle movement and brain activity. These receptors play a key role in processes like learning, memory, and mood regulation. Nicotine binds to these receptors, which is why smoking can create feelings of pleasure and alertness but can also lead to addiction as the brain adapts to the presence of nicotine over time.
