The pons is located between the medulla oblongata and the cerebral peduncles.
Pons is marked off from these ventrally by the anterior and the posterior transverse grooves. When viewed ventrally it is elongated, convex in both directions and presents a median groove, which lodges the basilar artery.
- Laterally a large part of it curves dorsally and backward into the base of the cerebellum forming the middle cerebellar peduncle.
- The dorsal surface is blended on each side with the overlying anterior cerebellar peduncle. The central free part forms the anterior part of the floor of the fourth ventricle.
- Pons contains nuclei, which form the cell stations in the cortico-pontocerebellar pathway, which effects coordination between the motor cortex and cerebellum.
