This is what most people think of as a muscle contraction.

I couldn't let go because the muscle contraction would pull it back in again and cause more damage.

This idea was an important step toward the current understanding of how nerves actually cause muscle contraction.

As a result, only feeble muscle contractions can take place.

The higher the recruitment the stronger the muscle contraction will be.

To stop smooth muscle contraction this change needs to be reversed.

This approach is in accordance with the following mechanism of muscle contraction.

Smooth muscle contraction is initiated by the release of Ca2+.

This was a major breakthrough in the understanding of how muscle contractions are regulated.

Voluntary muscle contraction is controlled by the central nervous system.
