Select the best description for the function of the lateral corticospinal tract:

B) impulses that move the head and eyes in response to visual stimuli
C) conveys nerve impulses from motor cortex to skeletal muscles of head and neck to coordinate precise, voluntary movements
D) impulses for subconscious proprioception
E) impulses for precise voluntary movements of the hands and feet

Question

Quizplus · Accepted Answer

The lateral corticospinal tract is primarily responsible for conveying nerve impulses from the motor cortex to the spinal cord, which then project to motor neurons that innervate skeletal muscles. This pathway is crucial for the execution of precise, voluntary movements, particularly in the distal parts of the limbs, such as the hands and feet.
