Anatomy of the Spinal Trigeminal Nucleus
- The spinal nucleus is composed of three subnuclei: subnucleus oralis, subnucleus caudalis, and subnucleus interpolaris.
- The subnucleus oralis is associated with the transmission of discriminative tactile sense from the orofacial region.
- The subnucleus interpolaris is associated with the transmission of tactile sense and dental pain.
- The subnucleus caudalis is associated with the transmission of nociception and thermal sensations from the head.
- This region is also denoted as sp5 in other neuroanatomical nomenclature.
Efferents of the Spinal Trigeminal Nucleus
- The spinal trigeminal nucleus projects to the ventral posteriomedial (VPM) nucleus in the contralateral thalamus via the ventral trigeminal tract.
Relations of the Spinal Trigeminal Nucleus
- The spinal trigeminal nucleus is situated lateral to the nucleus of tractus solitarius.

The spinal trigeminal nucleus is a nucleus in the medulla that receives information about deep/crude touch, pain, and temperature from the ipsilateral face. In addition to the trigeminal nerve (CN V), the facial (CN VII), glossopharyngeal (CN IX), and vagus nerves (CN X) also convey pain information from their areas to the spinal trigeminal nucleus. Thus the spinal trigeminal nucleus receives afferents from cranial nerves V, VII, IX, and X.
