The nucleus is divided into three parts, from rostral to caudal (top to bottom in humans):
- The spinal trigeminal nucleus is further subdivided into three parts, from rostral to caudal:
- Pars oralis (from the Pons to the Hypoglossal nucleus)
- Pars interpolaris (from the Hypoglossal nucleus to the obex)
- Pars caudalis (from the obex to C2)
There is also a distinct trigeminal motor nucleus that is medial to the principal sensory nucleus.
