Answer #1

Ans. This statement is true. When muscles contract, they shorten. Therefore, the movement that muscles can make is to pull the insertion toward the origin.It happens throughout due to the the length of the muscle which generate force at origin and insertion. This causes the muscle to shorten and changes the joint angle.
