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.
