The pons is located in the brainstem between the midbrain and medulla oblongata, in front of the cerebellum. … The pons can be roughly divided into two parts: the basal part of the pons (ventral pons) and the pontine tegmentum (dorsal pons).

What part of the brain is the pons?

pons, part of the brainstem above the medulla and below the cerebellum and the fourth ventricle cavity. The pons is a broad horseshoe-shaped transverse nerve fiber mass that connects the medulla oblongata to the cerebellum.

What is Pontin?

pons is a major part of the brain stem. It is located above the medulla and below the midbrain, anterior (anterior) to the cerebellum. … pontine tegmentum includes the tissue between the basal pons and the fourth ventricle; the pons forms the base of the fourth ventricle.

Are the pons and the brain stem the same?

pons is Largest part of the brain stem, located above the medulla and below the midbrain. It is a group of nerves that connects the brain and the cerebellum (pons means bridge in Latin).

What are pontine fibers?

The fibers that give the pons its name are Efferent fibers from the midline of the pons The nucleus is located in the central part of the cerebellar cortex. Fibers from the cerebral cortex reach the pontine nucleus in the corticopontine tract, passing through the internal capsule on the way to the pons.
