Martha Bagnall, The vestibular nuclei comprise several subdivisions (see Chapter 29) and are Vestibular System. The spinal vestibular The vestibular portion of the eighth cranial nerve informs the brain about the linear and angular movements of the head in space and the position of the head with respect to gravity. The termination sites of these eighth nerve afferents define the territory of the vestibular nuclei in the brainstem. (There is also a subset of afferents that project Vestibular Nuclei Vestibular System.

The vestibular nerve travels to the medulla where it synapses on four vestibular nuclei. This happens bilaterally. Further projections from the vestibular nuclei include . 1. Descending medial longitudinal fasciculus 2. Ascending medial longitudinal fasciculus 3. Vestibulospinal tract 4. Vestibulocerebellar tracts 5. Pathway to the vomiting center

They are also connected to the cerebellum which allows for coordination and fine-tuning. Some relays from the vestibule also go directly to the cerebellar nuclei bypassing the vestibular nuclei.

These nuclei contain the bodies of second-order neurons of the vestibular pathway. Vestibular Nucleus, Lateral Yttre balanskärnan Engelsk definition. Vestibular nucleus lying immediately superior to the inferior vestibular nucleus and composed of large multipolar nerve cells. Its upper end becomes continuous with the superior vestibular nucleus. (a) The medial (dorsal or chief vestibular nucleus), corresponding to the lower part of the area acustica in the rhomboid fossa; the caudal end of this nucleus is sometimes termed the descending or spinal vestibular nucleus. The medial vestibular nucleus (Schwalbe nucleus) is one of the vestibular nuclei. It is located in the medulla oblongata .
