Principal Sensory Nucleus
The principal sensory nucleus of trigeminal nerve (or chief sensory nucleus of V, main trigeminal sensory nucleus) is a group of second-order neurons which have cell bodies in the caudal pons. It receives information about discriminative sensation and light touch of the face as well as conscious proprioception of the jaw via first order neurons of CN V. * Most of the sensory information crosses the midline and travels to the contralateral ventral posteromedial nucleus (VPM) of the thalamus via the anterior trigeminothalamic tract The ventral trigeminal tract, ventral trigeminothalamic tract, anterior trigeminal tract, or anterior trigeminothalamic tract, is a nerve tract, tract composed of second-order neuron, second-order neuronal axons. These afferent fibers carry sensor .... * However, information of the ''oral cavity'' travels to the ipsilateral VPM of the thalamus via the dorsal trigeminothalamic tract. {{Authority control Cranial nerve nuclei Trigeminal nerve Pons ...
