A universal and absolute fact or truth about a specific action or phenomenon is known as a law.
For example, there is a natural law that says that there are certain rights that all people living on Earth should have equally without discrimination. It is a universal truth, a fact, and thus it was even made into a law in America within its Declaration of Independence.
ACh is released into the synaptic cleft in response to an action potential in the motor neuron. Gradient potentials are started when ACh binds to sarcolemma receptors.
<h3>What triggers a muscle contraction when an action potential occurs?</h3>
The ryanodine receptors (RyRs) in the SR also open and release calcium as a result of the action potential's invasion of the T-tubules, which opens the L-type calcium channels and stimulates contraction.\
Sodium ions within a muscle cell start the action potential. When a muscle contracts, calcium ions are released into the muscle cell, strengthening the muscle. This occurs after the cell becomes positive, starting the action potential.
