Inferior cerebellar peduncles

The inferior cerebellar peduncles (ICP) are paired structures containing important white matter fibre tracts which connect the cerebellum to the medulla.

Gross anatomy 

The inferior cerebellar peduncles are composed of a large restiform body and a small juxtarestiform body.

They contain the following afferent fibre tracts:

  • vestibulocerebellar tract
  • posterior spinocerebellar tract
  • cuneocerebellar tract
  • olivocerebellar tract
  • fibres from the pontine nuclei and reticular formation

The only efferent fibre tract passing through the ICP is the cerebellovestibular tract. 

Blood supply

The inferior cerebellar peduncles predominantly receive their arterial blood supply through branches of the posterior inferior cerebellar artery 1-3
