What is the 1st step in the mechanism of skeletal muscle contraction? |
Nerve impulse |
|
|
What is the 2nd step in the mechanism of skeletal muscle contraction? |
Acetylcholine is released from the neurons and bind to the muscle. |
|
|
What is the 3rd step of the mechanism of skeletal muscle contraction? |
