What is the vetnral spinocerebellar tract composed of?
Do they enter contralaterally or ipsilaterally? What inpt does it get?
Do they enter contralaterally or ipsilaterally? What inpt does it get?
- composed of axons of large neurons located between the dorsal and ventral grey columns of the spinal cord.
- the axons cross the midline in their segment of orgion, ascend thorugh the inferior peduncle, before entering the cerebellum via the contalateral superior pedunce.
they therefore cross the midline twice and so return ipsilateral to their side of origin on entering the cerebellum.
- get sensory input from various types of large receptive field afferents, including those of flexor reflex system,
- also receive input from all desceding tracts (corticospinal, reticulospinal and vestibulospinal)
