Pons
Pons is situated in front of cerebellum, below the mid brain and above the medulla oblongata.
It consist mainly nerve fibers (white mater) that form a bridge between two hemisphere of cerebellum and of fibers passing between higher levels of brain and spinal cord.
There are nuclei within pons that act as relay station, other nuclei in pons are pneumotaxic centre and apneustic center. These areas help to control breathing along with medullary respiratory area.
Pons also have nuclei associated with cranial nerves.
The anatomical structure of pons differs from that of cerebrum, in that cell bodies (grey mater) lie deeply and nerve fibers are on surface.
