Pons. The ventral and the dorsal. Pons is separated from medulla in front by a furrow in which the abducent facial and acoustic nerves appear Figs.
The pons is a portion of the brain stem located above the medulla oblongata and below the midbrain. In simple words in humans the pons is above the medulla oblongata below the midbrain and anterior to the cerebellum. On gross examination pons has convex anterior surface with shallow groove in the middle for the basilar artery.
The Pons serves a specific function in the brain.
The ventral portion of pons contains pontine nuclei vertically traversing corticopontine and corticospinal tracts and transversely crossing fibers arising from pontine. The transverse sections of pons appear pear-shaped. Any damage to pons can cause a loss of sensation in the face loss of ability to gaze and loss of a corneal reflex.
