(FRAME-INFO (STRING "Caudal Pons, Computer Reconstruction. This reconstruction shows the motor root of the trigeminal nerve \(V\) as it exits the brainstem at the level of the caudal pons. Its fibers originate in cells in the motor nucleus of the trigeminal nerve \(a branchial, or \"special visceral\" motor nucleus, here shown in green\) and innervate the muscles of mastication and the tensor tympani, tensor palatini, mylohyoid and digastric \(anterior belly\) muscles. The motor fibers are distributed to their target structures via the mandibular division of the trigeminal nerve. The trigeminal nerve is a mixed nerve and contains sensory fibers also, which terminate in sensory nuclei of the trigeminal nerve \(in yellow\), predominantly in the chief sensory nucleus of the trigeminal nerve or in the spinal trigeminal nucleus.
