Respuesta :
It is in the medulla oblongata that corticospinal tracts decussate meaning that the motor fibers originating from the right cerebral cortex descend through the left side of the spinal cord and vice versa.
The corticospinal tract controls the primary motor activity of the somatomotor system from the neck to the feet. It is the main line of the spine involved in voluntary movement. The tract originates in the primary motor cortex, where the soma of pyramidal neurons resides within corticospinal pathways in cortical layer V.
The large descending motor pathway carries voluntary impulses from the brain to the skeletal muscles. The corticospinal tract is a motor pathway primarily composed of motor axons that carry motor information from the cerebral cortex and brainstem to muscles for voluntary movement. The corticospinal tract is a white matter motor pathway that originates in the cerebral cortex and ends in the lower motor neurons and interneurons of the spinal cord.
