What is fastigial nucleus?
What is fastigial nucleus?
The fastigial nucleus is located in the cerebellum. It is one of the four deep cerebellar nuclei (the others being the nucleus dentatus, nucleus emboliformis and nucleus globosus), and is grey matter embedded in the white matter of the cerebellum.
What is the lateral Interpositus nucleus?
The interposed nucleus is part of the deep cerebellar complex and is composed of the globose nucleus and the emboliform nucleus. It is located in the roof (dorsal aspect) of the fourth ventricle, lateral to the fastigial nucleus. The interposed nucleus is smaller than the dentate but larger than the fastigial nucleus.
What are the four cerebellar nuclei?
From lateral to medial, the four deep cerebellar nuclei are the dentate, emboliform, globose, and fastigii.
Where is Fastigial nucleus located?
The fastigial nucleus constitutes one of the primary cerebellar nuclei and is situated closest to the midline toward the anterior segment of the superior vermis and over the roof of the fourth ventricle. [2][3] Compared to the dentate and interposed nuclei, it is the smallest and the oldest.
Where is Fastigial nucleus?
The Fastigial Nucleus. The fastigial nucleus, the target nucleus of the A zone both in cats and monkeys, projects bilaterally and symmetrically to the vestibular nuclei and to the contralateral medial bulbar reticular formation and the cervical cord (Voogd, 1964, Batton et al., 1977, Asanuma et al., 1983b).
Where is the Interpositus nucleus?
The anterior interpositus nucleus is a deep cerebellar nucleus that lies immediately to the medial side of the nucleus dentatus, and partly covering its hilum. It is one among the four pairs of deep cerebellar nuclei, which are from lateral to medial: the dentate, interposed, and fastigial nuclei.
What does the pontine nucleus do?
The pontine nuclei (PN) are the largest of the precerebellar nuclei, neuronal assemblies in the hindbrain providing principal input to the cerebellum. The PN are predominantly innervated by the cerebral cortex and project as mossy fibers to the cerebellar hemispheres.
What do cerebellar nuclei do?
The cerebellar deep nuclei are the sole outputs of the cerebellum. The fastigial nucleus is the most medially located of the cerebellar nuclei. It receives input from the vermis and from cerebellar afferents that carry vestibular, proximal somatosensory, auditory, and visual information.
What does the Arbor Vitae do?
The arbor vitae /ˌɑːrbɔːr ˈvaɪtiː/ (Latin for “tree of life”) is the cerebellar white matter, so called for its branched, tree-like appearance. In some ways it more resembles a fern and is present in both cerebellar hemispheres. It brings sensory and motor information to and from the cerebellum.
Which part of the brain controls balance?
cerebellum
The cerebellum is at the back of the brain, below the cerebrum. It’s a lot smaller than the cerebrum. But it’s a very important part of the brain. It controls balance, movement, and coordination (how your muscles work together).
