The hypoglossal nucleus is a cranial nerve nucleus, and it extends the length of the medulla, and being a motor nucleus, is close to the midline. In the open medulla, it is visible as what is known as the hypoglossal trigone, a raised area (medial to the vagal trigone) protruding slightly into the fourth ventricle.

In the closed medulla, the gracile and cuneate nuclei lie posteriorly, which means the nucleus is not as close to the back of the medulla as in the open medulla. It is, however, still close to the midline.

Mapping of Neurotensin in the Alpaca (Lama pacos) Brainstem.

de Souza E1, Aguilar LA, Díaz-Cabiale Z, Narváez JA, Coveñas R.
Anatomia, histologia, embryologia.Anat Histol Embryol.2014 Aug;43(4):245-56. doi: 10.1111/ahe.12067. Epub 2013 May 22.
We studied the distribution of cell bodies and fibres containing neurotensin (NT) in the brainstem of the alpaca using an indirect immunoperoxidase technique. Immunoreactive fibres were widely distributed throughout the brainstem, whereas the distribution of cell bodies was less widespread. Immunore

Introduction: Animal studies have shown inhibitory connections between the sensory trigeminal nucleus and hypoglossal nucleus. I investigated if these inhibitory projections are present in man. Methods: I examined 18 healthy subjects, 2 patients with brainstem stroke, and 5 patients with multiple sc
