Spinal motor tracts

WebThe pyramidal tracts include both the corticobulbar tract and the corticospinal tract. These are aggregations of efferent nerve fibers from the upper motor neurons that travel from the cerebral cortex and terminate either in the brainstem ( corticobulbar) or spinal cord ( corticospinal) and are involved in the control of motor functions of the ... WebThe corticospinal tracts are the final output of the motor system, conveying the action plan to the alpha motor neurons of the anterior horns of the spinal cord, which, in turn, relay the signals to move the muscles by way of peripheral nerves ().The corticospinal tracts are sometimes referred to as the pyramidal system (since they travel for part of their course …
