Which arteries are responsible for supplying the pons?

The pontine arteries are specifically tasked with supplying blood to the pons, which is a critical structure located in the brainstem. These arteries branch off the basilar artery, which is formed by the convergence of the two vertebral arteries. The pontine arteries provide essential oxygen and nutrients to this area, allowing it to perform its various functions, including regulating motor control, sensory analysis, and the involvement in the autonomic functions necessary for survival.

In contrast, the superior cerebellar arteries primarily supply blood to the upper part of the cerebellum and parts of the midbrain, rather than the pons itself. The posterior cerebral arteries mainly supply the occipital lobe and some parts of the temporal lobe, while the anterior choroidal arteries supply parts of the internal capsule, hippocampus, and lateral geniculate nucleus, not the pons. Therefore, the pontine arteries are the most directly associated with the vascularization of the pons.
