The spinal trigeminal nucleus is a nucleus in the medulla that receives information about deep/crude touch, pain, and temperature from the ipsilateral face. The facial (cranial nerve 7), glossopharyngeal (CN9), and vagus nerves (CN10) also convey pain information from their areas to the spinal trigeminal nucleus.^[1] Thus the spinal trigeminal nucleus receives input from cranial nerves 5,7,9,10.

This nucleus projects to the ventral posterior medial nucleus in the dorsal thalamus.
