The pontine tegmentum, or dorsal pons, is the dorsal part of the pons located within the brainstem. The ventral part or ventral pons is known as the basilar part of the pons. The pontine tegmentum is all the material dorsal from the basilar pons to the fourth ventricle. Along with the dorsal surface of the medulla oblongata, it forms part of the rhomboid fossa – the floor of the fourth ventricle.
Its contents include several cranial nerve nuclei, the reticulotegmental nucleus, the pedunculopontine nucleus and the laterodorsal tegmental nucleus. It also houses the pontine respiratory group of the respiratory center which includes the pneumotaxic centre, and the apneustic centre.
