acetylcholinesterase

Acetylcholinesterase is an enzyme in the nervous system that breaks down a chemical called acetylcholine, which helps transmit signals between nerve cells. When a nerve signals to another cell, acetylcholine is released to carry the message. Acetylcholinesterase quickly deactivates acetylcholine afterward, ensuring signals are clear and properly timed. This process is essential for normal nervous system function, including muscle movement and brain activities. If acetylcholinesterase doesn’t work properly, signals can become overstimulated or delayed, leading to issues like muscle weakness or neurological problems.
