Vertex Fitness | How Muscles Contract

The calcium comes in and bonds with the troponin. This bonding pulls the tropomyosin away from the binding sites and allows the muscle to contract. Once the key unlocks the lock, we apply a little energy to make a contraction. Adenosine Triphosphate (ATP) is the fuel of cells.

How does acetylcholine stimulate muscle contraction?

2020/5/17· The outflow of calcium allows the myosin heads access to the actin cross-bridge binding sites, permitting muscle contraction. Also to know is, what stimulates a muscle to contract? For a contraction to occur there must first be a stimulation of the muscle in the form of an impulse (action potential) from a motor neuron (nerve that connects to muscle ).
