The middle cerebellar peduncles (brachia pontis) are composed entirely of centripetal fibers, which arise from the cells of the nuclei pontis of the opposite side and end in the cerebellar cortex; the fibers are arranged in three fasciculi, superior, inferior, and deep.

  • The superior fasciculus, the most superficial, is derived from the upper transverse fibers of the pons; it is directed backward and lateralward superficial to the other two fasciculi, and is distributed mainly to the lobules on the inferior surface of the cerebellar hemisphere and to the parts of the superior surface adjoining the posterior and lateral margins.
  • The inferior fasciculus is formed by the lowest transverse fibers of the pons; it passes under cover of the superior fasciculus and is continued downward and backward more or less parallel with it, to be distributed to the folia on the under surface close to the vermis.
  • The deep fasciculus comprises most of the deep transverse fibers of the pons. It is at first covered by the superior and inferior fasciculi, but crosses obliquely and appears on the medial side of the superior, from which it receives a bundle; its fibers spread out and pass to the upper anterior cerebellar folia. The fibers of this fasciculus cover those of the restiform body.

The cerebellar white matter may be a third germinal zone in the cerebellum; however, its function as a germinal zone is controversial.
These structural relationships are generally maintained in the neuronal connections between the nuclei and associated cerebellar cortex, with the dentate nucleus receiving most of its connections from the lateral hemispheres, the interposed nuclei receiving inputs mostly from the paravermis, and the fastigial nucleus receiving primarily afferents from the vermis.
In the cerebellum, the PICA supplies blood to the posterior inferior portion of the cerebellum, the inferior cerebellar peduncle, the nucleus ambiguus, the vagus motor nucleus, the spinal trigeminal nucleus, the solitary nucleus, and the vestibulocochlear nuclei.

The petrosal surface is the cerebellar surface that faces the posterior surface of the petrous bone, and is the cerebellar surface that is compressed by an acoustic schwannoma.
The cerebellomedullary fissure, the cleft between the cerebellum and medulla that extends upward between the cerebellar tonsil and the medulla, communicates with the inferior limb of the cerebellopontine fissure near the lateral recess of the fourth ventricle.
The superior cerebellar artery, which is separated from the tumor by the trigeminal nerve, is displaced rostrally by the tumor, and the posterior inferior cerebellar artery is displaced caudally with the glossopharyngeal and vagus nerves.
