Anatomy of the pons
The "knob-like" shaped on the anterior (front) of the pons is formed by transverse pontine fibres that travel from one side (left or right) to the other. Most other fibres in the brainstem travel up and down.
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.
Cranial nerve nuclei
A number of cranial nerve nuclei are present in the pons. The chief or pontine nucleus of the trigeminal nerve sensory nucleus, as well as the motor nucleus for the trigeminal nerve, are present in the mid-pons.
