GENERAL SENSORY – contained in V1, V2 and V3. Principal general sensory for all of the head. 1st order sensory neurons relay to 2nd order sensory neurons in the following Trigeminal sensory nucleii:
Mesencephalic nucleus (Midbrain) - muscle proprioception
Pontine Trigeminal nucleus (Pons) - touch
Nucleus of spinal tract (Pons – Spinal cord)- pain and tempurature
