Axons of the Lower Motor Neurons of the Anterior Corticospinal

Question

Axons of the lower motor neurons of the anterior corticospinal tracts innervate ________.
A) skeletal muscles that control skilled movements in the limbs
B) skeletal muscles of the neck and upper limb
C) muscles of the respiratory system
D) muscles of urinary bladder
E) muscles of the lower digestive tract

Accepted Answer

The anterior corticospinal tract controls the voluntary movement of the limbs and trunk by innervating the lower motor neurons in the spinal cord. Specifically, the axons of the lower motor neurons of the anterior corticospinal tracts innervate the skeletal muscles of the neck and upper limb.
