The pons (sometimes pons Varolii after Costanzo Varolio) is a structure located on the brain stem. It is rostral to the medulla oblongata, caudal to the midbrain, and ventral to the cerebellum.

The posterior (back) surface of the pons forms part of the wall of the fourth ventricle of the brain.
Most blood to the pons is supplied by pontine arteries. These are small arteries that branch off the basilar artery of the Circle of Willis. Blood also comes from the anterior inferior, and superior cerebellar arteries.
There are two main domains in the pons for control of respiration:
