This region is located towards the posterior end of the frontal lobe in the cerebral cortex and is associated with the primary motor cortex. The axons of upper motor neurons related to voluntary muscle movement travel along the cns in two pathways – the corticospinal and corticobulbar tracts.

The lateral corticospinal tract is responsible for the control of the distal musculature and the anterior corticospinal tract is responsible for the control of the proximal musculature.
The part of the brain that does the job of executing voluntary movements is the motor cortex. The required movements are carried out in such a way that they best suit the individual’s current position.

However, it is still unclear how and what information the somatosensory system receives during movement.

Voluntary movements include everything from moving your hands and legs to controlling facial expressions and even some swallowing motions. Signals from the primary motor cortex cross over the body’s midline to activate muscles on the opposite side of the body.
