This tract originates at the ipsilateral Clarke's nucleus (T1-L1) and travels upward to reach the inferior cerebellar peduncle and synapses within the spinocerebellum (also known as the paleocerebellum). Cuneocerebellar tract: unconscious proprioceptive information from the upper limb and neck. This tract originates at the ipsilateral accessory ...
The two main tracts are the dorsal spinocerebellar tract, and the ventral spinocerebellar tract. Both of these tracts are located in the peripheral region of the lateral funiculi (white matter columns). [1] Other tracts are the rostral spinocerebellar tract, and the cuneocerebellar tract (posterior external arcuate fibers). [2]
It relays unconscious proprioceptive sensory information from the upper limb and upper trunk to the cerebellum via the cuneocerebellar fibers. [ 2 ] The neurons of the ACN (as well as those of the lateral portion of the cuneate nucleus) are functionally homologous with the posterior thoracic nucleus ; the cuneocerebellar fibers are therefore ...
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
The arbor vitae / ˌ ɑːr b ɔːr ˈ v aɪ t iː / (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. [1]
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.
The spino-olivary tract is a non-specific indirect ascending pathway and is connected to the inferior olivary nuclei. The axons enter the spinal cord from the dorsal root ganglia and terminate on unknown second-order neurons in the posterior grey column . [ 2 ]
The cerebellar vermis (from Latin vermis, "worm") is located in the medial, cortico-nuclear zone of the cerebellum, which is in the posterior fossa of the cranium.The primary fissure in the vermis curves ventrolaterally to the superior surface of the cerebellum, dividing it into anterior and posterior lobes.
