In this regard, what is the pathway of the corticospinal tract?
The corticospinal pathway is a one-neuron pathway from the cerebral cortex to the gray of the spinal cord. This pathway consists of all axons that: (1) originate from cells within the cerebral cortex, (2) pass through the pyramids of the medulla, and (3) terminate in the spinal cord.
Also Know, what type of fibers are found within the corticospinal tract? 9.1 Pyramidal tracts These are called as pyramidal tracts as they crossover at the level of the pyramids in the medulla. They are collections of upper motor neuron fibers which go to the spinal cord (corticospinal) or the brainstem (corticobulbar) and control the motor function of the body.
Considering this, what does the corticospinal tract control?
The corticospinal tract is a white matter motor pathway starting at the cerebral cortex that terminates on lower motor neurons and interneurons in the spinal cord, controlling movements of the limbs and trunk. The corticospinal tract is one of the pyramidal tracts, the other being the corticobulbar tract.
What does damage to the corticospinal tract cause?
Injuries to the lateral corticospinal tract results in ipsilateral paralysis (inability to move), paresis (decreased motor strength), and hypertonia (increased tone) for muscles innervated caudal to the level of injury.  The lateral corticospinal tract can suffer damage in a variety of ways.
