The sensory '''trigeminal nerve nucleus''' is the largest of the [[cranial nerve]] nuclei, and extends through the whole of the [[brainstem]], [[midbrain]] to [[Medulla oblongata|medulla]].
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")
* 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.
