Final answer:

Acetylcholinesterase breaks down acetylcholine to prevent extended muscle contraction, calcium binds to troponin facilitating muscle contraction.


Explanation:

Acetylcholinesterase plays a crucial role in preventing unwanted, extended muscle contraction by breaking down acetylcholine in the synaptic cleft, ensuring the quick termination of its action on the muscle receptors. When acetylcholine is broken down, it does not remain bound to its receptors, preventing uncontrolled muscle contractions. Additionally, calcium is involved in muscle contraction as it binds to troponin, causing tropomyosin to move and enable muscle contraction.
