Respuesta :

Answer:

C

Explanation:

Bones are moved at the joints by muscles. It requires at least two muscles acting antagonistically on the bone to move the joint. When one muscle contracts, the other relaxes. Muscles are attached to bones through tendons. An example is the humerus (bone of the upper arm) is moved at the elbow by the antagonistic action of the biceps and triceps.
