Question

explain the muscle contraction​

Answer 1

Answer:

Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.

Answer 2

Explanation:

Contractions can have causes that aren't due to underlying disease. Examples include normal pregnancy, natural labour, orgasm or menstruation.
