Neuron II.âFrom cells located in the posterior gray column and intermediategray matter fibers run in the ventral spinocerebellar tracts of the same oropposite side through the spinal cord, medulla oblongata and pons, bend aroundthe brachium conjunctivum, and then course back along the anterior medullaryvelum to the cortex of the rostral part of the vermis (Fig. 235, blue). 3H THE NERVOUS SYSTEM (.By Way of the Dorsal Spinocerebellar Tract: Neuron I.âThe first neuron of this chain is similar to the primary neuronin the three preceding paths. The impulses, however, travel over those col-lateral and terminal branches of the dorsal root fibers which ramify about thecells of the nucleus dorsalis.

Neuron ITâFrom cells in the nucleus dorsalis fibers run to the dorsal spino-cerebellar tract of the same side and through the restiform body to the cortexof both the rostral and the caudal portions of the vermis (Fig. 235, red). Cerebellar Connections of the Vestibular Nerve.âThe vestibular nerve THE GREAT AFFERENT SYST1 M 5 315 conducts impulses from specialized sense organs in the semicircular canalscule and utricle, which are stimulated by movements and changes in posture of the head.
