Superior cerebellar peduncle contains mainly which tract ?
Ans. is 'a' i.e., TectocerebellarSuperior cerebellar peduncle This is the major output of the brain and connects to the midbrain, the cerebellothalamic tract (to the thalamus), and the cerebellorubral tract (to the red nucleus). It receives afferents from the locus coeruleus, and ventral spinocerebellar tract.Middle cerebellar peduncle This is the largest peduncle and connects the cerebellum to the pons. It connects the contralateral pontine nucleus to the cerebellar coex and also carries the input from the contralateral cerebral coex. It is composed of three fasciculi including the superior, inferior and deep.Inferior cerebellar peduncleThis connects the spinal cord and medulla to the cerebellum. The posterior spinocerebellar tract receives proprioceptive information from the body. The cuneocerebellar tract receives proprioceptive input from the upper limb and neck. The trigeminocerebellar tract sends proprioceptive input from the face. The juxtarestiform is an efferent system here.
