The spinal trigeminal nucleus is a
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.[1] Thus the spinal trigeminal nucleus receives afferents from cranial nerves V, VII, IX, and X
.
Anatomy
Structure
The spinal nucleus is composed of three subnuclei: subnucleus oralis (pars oralis), subnucleus caudalis (pars caudalis), and subnucleus interpolaris (pars interpolaris). The subnucleus oralis is associated with the transmission of discriminative (fine)
dental pain, whereas the subnucleus caudalis is associated with the transmission of nociception
and thermal sensations from the head.
This region is also denoted at sp5 in other neuroanatomical nomenclature.[2]
Efferents
This nucleus projects to the ventral posteriomedial (VPM) nucleus in the contralateral thalamus via the ventral trigeminal tract.[3]
Relations
The nucleus is situated lateral to the
nucleus of tractus solitarius.[4]
