Acetylcholine Receptor

Acetylcholine receptors are specialized protein structures located on the surface of nerve and muscle cells. They detect the chemical messenger acetylcholine, which is released by nerve cells to communicate with muscles or other nerves. When acetylcholine binds to these receptors, they undergo a change that triggers a response, such as muscle contraction or nerve signal transmission. These receptors are essential for many functions, including movement, learning, and memory, and their proper operation is crucial for the nervous system to work effectively.
