(FRAME-INFO (STRING " Arm Corticospinal Fiber. In this lateral dissection, a corticospinal neuron controlling an arm muscle \(blue\) is shown originating in the precentral gyrus \(primary motor cortex\). It passes in turn through the central white matter \(corona radiata\), the posterior limb of the internal capsule, the central part of the crus cerebri \(cerebral peduncle\), the base of the pons and the medullary pyramid.  It will cross in the pyramidal decussation \(not shown\) to the lateral funiculus of the spinal cord before terminating in spinal cord gray. "))
