Upper motor neuron which innervate muscle of face and head are located near the lateral fissure of brain. Their axons join to form corticobulbar tract. These axons then descend in internal capsule(genu) of cerebral peduncle. The UMN then synapse on LMN(lower motor neuron) cranial nerve nuclei which are located in midbrain, pons, medulla.
