The fastigial nuclei is situated atop the roof of the fourth ventricle (thence its name: "fastigus" is Latin for "summit"). [1]The fastigial nucleus is a mass of gray matter nearest to the middle line at the anterior end of the superior vermis, immediately over the roof of the fourth ventricle (the peak of which is called the fastigium), from which it is separated by a thin layer of white matter.
There are four paired deep cerebellar nuclei embedded in the white matter centre of the cerebellum. The nuclei are the fastigial, globose, emboliform, and dentate nuclei. In lower mammals the emboliform nucleus appears to be continuous with the globose nucleus, and these are known together as the interposed nucleus. [1]
It sends fibres to deep cerebellar nuclei (including the fastigial nucleus) which in turn project to both the cerebral cortex (via midbrain and thalamus) and the brain stem (via reticular formation in the pons, and vestibular nuclei in the medulla oblongata), thus providing modulation of descending motor systems. The spinocerebellum contains ...
It is located dorsal to the fourth ventricle and lateral to the fastigial nucleus; it receives afferent neuronal supply from the anterior lobe of the cerebellum and sends output via the superior cerebellar peduncle and the red nucleus. [8] The fastigial nucleus is the most medial efferent cerebellar nucleus, targeting the pontine and medullary ...
The vestibulocerebellar tract fibers are second-order fibers from the vestibular nuclei, and first-order fibers from the vestibular ganglion/nerve. [1] They pass through the juxtarestiform body of the inferior cerebellar peduncle to reach the cerebellum, [1] They terminate in the vestibulocerebellum, and part of the vermis as well as the dentate nucleus, and fastigial nucleus in each ...
Fourth ventricle location shown in red (E), pons (B); the floor of the ventricle is to the right, the roof to the left. The fourth ventricle has a roof at its upper (posterior) surface and a floor at its lower (anterior) surface, and side walls formed by the cerebellar peduncles (nerve bundles joining the structure on the posterior side of the ventricle to the structures on the anterior side).
The lateral vestibulospinal tract is one of the descending spinal tracts of the ventromedial funiculus.. The lateral part of the vestibulospinal tract is the major portion and is composed of fibers originating in the lateral, superior, and inferior vestibular nuclei (primarily the lateral).
It brings sensory and motor information to and from the cerebellum. The arbor vitae is located deep in the cerebellum. Situated within the arbor vitae are the deep cerebellar nuclei; the dentate, globose, emboliform and the fastigial nuclei. These four different structures lead to the efferent projections of the cerebellum. [2]
