Détails de la réponse
Muscles act in opposite directions in order to cause a bone to move. The contraction of one muscle pulls the bone in one direction, while the contraction of the opposing muscle pulls the bone in the opposite direction, resulting in movement. This is how our body can perform complex movements such as walking, running, jumping, and lifting objects. The opposing action of muscles also helps to prevent dislocation at joints by keeping them stable and balanced. While muscles can experience fatigue, the opposing action of muscles does not prevent muscle fatigue directly. The regulation of bodily activities is controlled by the nervous and endocrine systems.
