The Corticospinal Tracts EXPLAINED | Motor Output

The video explains the corticospinal tracts, focusing on the lateral and anterior divisions. It details the pathway of upper motor neurons from the motor cortex through the brainstem, highlighting the decussation at the medulla oblongata. The lateral tract controls contralateral distal muscles, enabling fractionated movements, while the anterior tract controls bilateral postural muscles. The video also discusses the clinical implications of these tracts in stroke, emphasizing the differential impact on muscle control.

What is the role of lower motor neurons in the corticospinal pathway?

Discuss the bilateral control of muscles innervated by the anterior corticospinal tract.

How does a stroke in the right hemisphere of the brain affect muscle control on the left side of the body?
