It receives information about discriminative sensation and light touch of the face as well as conscious proprioception of the. Discrimination conscious proprioception and vibratory sense from the face to the thalamus VPM and brainstem centers blink or corneal reflex.
Neurons in motor V possess axons that innervate the muscles of mastication. At the level of. Cell bodies in the brainstem that send axons to spinal cord to inhibit pain transmission are located in.
Ophthalmic nerve CN V-1 b. Some older texts refer to it as the pontine trigeminal nucleus due to its location. Nucleus sensorius principalis nervi trigemini.
