1 Jaw-jerk reflex. Jaw-jerk reflex. Diagram shows the reflex arc subserving the jaw-jerk reflex. (Vmes indicates mesencephalic nucleus of the trigeminal nerve; Vp, principal sensory nucleus of the trigeminal nerve; Vm, trigeminal motor nucleus; Sp V tr, spinal trigeminal tract; III N, oculomotor nerve; Ohpth N, ophthalmic trigeminal root; Max N, maxillary trigeminal root; Mand N, mandibular trigeminal root; Mot Root V N, trigeminal motor root; VI N, abducens nerve, Mmsp, masseter muscle spindle; Mmf, masseter muscle fibers.)
