Question

Quizplus · Accepted Answer

The lateral corticospinal tracts are responsible for controlling voluntary movement in the limbs. The lower motor neurons of these tracts innervate skeletal muscles that control skilled movements in the limbs, such as those involved in manipulating objects and walking. Therefore, option A is the correct choice. The other options are incorrect because they involve muscles that are not innervated by the lateral corticospinal tracts.
