QuestionSBA
QuestionChoice
Incorrect. The dentate nucleus is the largest of the deep cerebellar nuclei within the cerebellar hemispheres. It receives input from the premotor cortex and supplementary motor area and outputs via the superior cerebellar peduncle.

e
Dentate nucleus
QuestionChoice
Correct. The superior cerebellar peduncles connect the cerebellum to the midbrain, outputting from the deep nuclei of the cerebellum to the red nucleus, ventrolateral nucleus of the thalamus (which projects to the primary motor cortex), and ventroanterior nucleus of the thalamus (which projects to the premotor and supplementary motor areas). The superior cerebellar peduncles decussate at the level of the inferior colliculi.

a
Left superior cerebellar peduncle
QuestionChoice
Incorrect. The middle cerebellar peduncles are the largest of all the cerebellar peduncles and connect the cerebellum to the pons. It consists of ponto-cerebellar mossy fibres carrying inputs to the cerebellum, arising from the pontine nucleus.

b
Left middle cerebellar peduncle
QuestionChoice
Incorrect. The inferior colliculi are nuclei on the dorsal surface of the midbrain, forming the lower prominences of the tectum. They are the principle nuclei of the midbrain involved in the auditory pathway.

d
Left inferior colliculus
QuestionChoice
Incorrect. The inferior cerebellar peduncles are the smallest of all the cerebellar peduncles and connect the cerebellum to the medulla. It consists of fibres carrying inputs to the cerebellum, arising from the inferior olive, as well as fibres from the dorsal spinocerebellar tract.
