- Trigeminal nerve nuclei
Brain: Trigeminal nerve nuclei The cranial nerve nuclei schematically represented; dorsal view. Motor nuclei in red; sensory in blue. (Trigeminal nerve nuclei are at "V".) Latin nuclei trigemini Gray's subject #187 787 NeuroNames ancil-1008020136 MeSH Trigeminal+nuclei NeuroLex ID nifext_11
The nucleus is divided into three parts, from rostral to caudal (top to bottom in humans):
- The mesencephalic nucleus
- The chief sensory nucleus (or "pontine nucleus" or "main sensory nucleus" or "primary nucleus" or "principle nucleus")
- The spinal trigeminal nucleus
The spinal trigeminal nucleus is further subdivided into three parts, from rostral to caudal:
- Pars Oralis
- Pars Interpolaris
- Pars Caudalis
There is also a distinct trigeminal motor nucleus that is medial to the chief sensory nucleus.
