tegmentum (dorsal) medulla which contains several cranial nerve nuclei and white matter tracts.ventral (anterior) medulla which contains the olive, pyramidal tracts, and CN IX to XII rootlets.Medulla is separated into two main parts: The superior broad part of the medulla joins the pons 2,3. The caudal border of the medulla is the 1 st cervical spinal nerves. pp.The medulla is approximately 3 cm in length and 2 cm in greatest diameter 2. Schmahmann JD (2000) Cerebellum and Brainstem.

The AICAs do not divide into medial and lateral major cerebellar branches but give off twigs to various structures. The AICAs supply only a small part of the anterior inferior cerebellum and the flocculus, but their major supply is to the lateral pontine tegmentum and the brachium pontis. Infarcts in the cerebellum are often limited to the territory of one of these branches. The PICAs and the SCAs, the two largest arterial pairs, have medial branches that supply mostly the vermian and paravermian portions of their respective regions of the cerebellum and lateral branches that supply the cerebellar hemispheres. The cerebellar arteries are distributed rostrocaudally so that the posterior inferior cerebellar arteries (PICAs) arise from the intracranial vertebral artery, a component of the proximal intracranial posterior circulation territory the anterior inferior cerebellar arteries (AICAs) originate from the basilar artery, a component of the middle intracranial posterior circulation territory and the most rostral arteries, the Superior cerebellar arteries (SCAs), arise near the basilar artery bifurcation and are included in the distal intracranial territory.
