Globose nucleus
The nucleus globosus (Latin for " ball core "), even nucleus interpositus posterior, is a core area in the cerebellum.
Anatomy
The nucleus globosus is applied respectively in both cerebellar hemispheres in humans with an approximate diameter of 5 mm, the smallest of the cerebellar nuclei and the core area. The name derives from his was more or less rounded form. It is located medial to the nucleus emboliform and laterally from the fastigial nucleus. Frequently nucleus globosus and nucleus emboliform be summarized as nucleus interpositus. The spherically arranged nerve cells vary in size, but the bulk of them is smaller than the fastigial nucleus. After the rostral nucleus often dissolves into individual cell groups, caudally it usually forms a thin but solid layer of cells.
Projections
Receives afferents of the nucleus globosus mainly of the Purkinje cells of the paravermalen ( intermediate ) and covering them zone of Spinocerebellums. The efferent fibers extend to a part in the tract cerebellorubralis via the superior cerebellar peduncle to the pars magnocellularis of the red nucleus and the oculomotor areas in the midbrain, and the nucleus of the thalamus ventrolateralis. On their way there, the paths cross in the decussation pedunculorum cerebellarium Superiorum ( = Stilling'sche scissors ) in the mesencephalic tegmentum to the contralateral side. Another part of the fibers of the nucleus globosus extends to the medulla oblongata.
