pons

 [ponz] (pl. pon´tes) (L.)
1. that part of the metencephalon lying between the medulla oblongata and the midbrain, ventral to the cerebellum; see also brainstem.
2. any slip of tissue connecting two parts of an organ.

pon·tes

(ponz, pon'tēz),
1. neuroanatom the pons varolii or pons cerebelli; that part of the brainstem between the medulla oblongata caudally and the mesencephalon rostrally, composed of the basilar part of pons and the tegmentum of pons. On the ventral surface of the brain, the basilar part of pons (that is, the white pontine protuberance) is demarcated from both the medulla oblongata and the mesencephalon by distinct transverse grooves. Synonym(s): pons cerebelli, pons varolii
2. Any bridgelike formation connecting two more or less disjoined parts of the same structure or organ.
[L. bridge]

pons

[ponz] pl. pontes
Etymology: L, bridge
1 also called bridge of Varolius. a prominence on the ventral surface of the brainstem, between the medulla oblongata and the cerebral peduncles of the midbrain. The pons consists of white matter and a few nuclei and is divided into a ventral part and a dorsal part. The ventral part consists of transverse fibers separated by longitudinal bundles and small nuclei. The dorsal part comprises the tegmentum, which is a continuation of the reticular formation of the medulla containing the nucleus of the abducens nerve, the nucleus of the facial nerve, the motor nucleus of the trigeminal nerve, the sensory nuclei of the trigeminal nerve, the nucleus of the cochlear division of the eighth nerve, the superior olive, and the nuclei of the vestibular division of the eighth nerve.

pons

1. Any anatomical structure joining two parts or bridging between them.
2. The middle part of the BRAINSTEM, lying below the cerebral peduncles of the midbrain and above the MEDULLA OBLONGATA. From the Latin pons, a bridge.

pons (ponz),

n a structure dorsal to the medulla and intimately related to the pathways to the cerebrum. The cranial nerves whose nuclei lie in the pons are the trigeminal, abducens, and facial nerves, and part of the acoustic nerve. It is intimately related to the medulla, has the same blood vessel supply, and is involved in many lesions that affect the medulla. It is especially involved with the cerebellar manifestations of disease and may cause serious muscular incoordination in motor function of the head, neck, and facial structures.
