Spinocerebellar tracts
It carries proprioceptive information from muscle spindles and Golgi tendon organs of ipsilateral part of trunk and lower limb.Axon fibers from Clarke's Nucleus convey this proprioceptive information in the spinal cord in the peripheral region of the lateral funiculus ipsilaterally.The fibers continue to course through the medulla oblongata of the brainstem, at which point they pass through the inferior cerebellar peduncle and into the cerebellum, where unconscious proprioceptive information is processed.The term "cuneocerebellar tract" is also used to describe exteroceptive and proprioceptive components that take origin in the gracile and cuneate nuclei; they pass to the inferior cerebellar peduncle of the same side.[8] It terminates bilaterally in the anterior lobe of the cerebellum (lower cerebellar peduncle) after travelling ipsilaterally from its origin in the cervical portion of the spinal cord.This is a column of relay neuron cell bodies within the medial gray matter within the spinal cord in layer VII (just beneath the dorsal horn), specifically between T1-L3.These neurons then send axons up the spinal cord, and project ipsilaterally to medial zones of the cerebellum through the inferior cerebellar peduncle.Below L3, relevant neurons pass into the gracile fasciculus (usually associated with the dorsal column–medial lemniscus pathway) until L3 where they synapse with the posterior thoracic nucleus (leading to considerable caudal enlargement).
