FALSE
Muscles can only contract (and then relax), not elongate.
Explanation:
Muscles function by means of their ability to contract and relax. They can't elongate.The movements are carried out by their synchronised contraction and relaxation actions and they typically function in pairs or groups.
For example, biceps and triceps of the upper arm. They act in a complimentary manner.
While bending (flexing) your elbow, as biceps contracts, triceps relaxes.
While stretching (extending) your arm, biceps relaxes as the triceps contracts.
Hope this helps.
