Q

Motor Decussation
The two pyramids contain the motor fibers that pass from the brain to the medulla oblongata and spinal cord.
These are the corticobulbar and corticospinal fibers that make up the pyramidal tracts.
About 90% of these fibers leave the pyramids in successive bundles and decussate (cross over) in the anterior median fissure of the medulla oblongata as the pyramidal decussation or motor decussation.
Having crossed over at the middle line, they pass down in the posterior part of the lateral funiculus as the lateral corticospinal tract. The other 10% of the fibers stay uncrossed in the anterior corticospinal tract. The pyramidal decussation marks the border between the spinal cord and the medulla oblongata. [1]
