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. ==See also== * [[Trigeminal nerve]] ==Additional images== <gallery> Image:Gray683.png|Dissection of brain-stem.
