The medial vestibular nucleus (Schwalbe nucleus) is one of the
vestibular nuclei
The vestibular nuclei (VN) are the cranial nuclei for the vestibular nerve located in the brainstem.
In Terminologia Anatomica, they are grouped in both the pons and the medulla in the brainstem

. It is located in the
medulla oblongata
The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem. It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic (involun ...

Lateral vestibulo-spinal tract (lateral vestibular nucleus “Deiters”)- via
ventrolateral medulla The ventrolateral medulla, part of the medulla oblongata of the brainstem, plays a major role in regulating arterial blood pressure and breathing. It regulates blood pressure by regulating the activity of the sympathetic nerves that target the hear ...

medial longitudinal fasciculus
The medial longitudinal fasciculus (MLF) is a prominent bundle of nerve fibres which pass within the ventral/anterior portion of periaqueductal gray of the mesencephalon (midbrain). It contains the interstitial nucleus of Cajal, responsible ...

It is one of the nuclei that corresponds to CN VIII, corresponding to the
vestibular nerve
The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other). In humans the vestibular nerve transmits sensory information from vestibular hair cells located in the two otolith organs (the u ...
, which joins with the
cochlear nerve
The cochlear nerve (also auditory nerve or acoustic nerve) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve. The cochlear nerve carries auditory sensory information ...

It receives its blood supply from the
Posterior Inferior Cerebellar Artery
The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain. Blockage of the posterior inferior cerebellar artery can ...
