Pons

Trancred 2005 The Pons is an important relay center for information passing from the cerebral cortex to the cerebellum. It also contains nuclei cranial nerves V, VI, and VII, respiratory control centers and long motor and sensory tracts. Structures: Basis Pontis CN Nuclei of Pons Corticobulbar Tract Corticopontine Tract Corticospinal Tract Fourth Ventricle Hindbrain Medial Lemniscus Medulla Midbrain Middle Cerebellar Peduncle Pontine Nuclei Pontocerebellar Tract Reticular Formation Spinothalamic Tract Tracts of Pons Information: The pons is the rostral part of the hindbrain and lies between the medulla and the midbrain. It develops from the metencephalon of the embryonic brain and consists of a tegmentum and a base (the basis pontis). The pontine tegmentum is located dorsally and forms the rostral part of the floor of the fourth ventricle. It is composed primarily of gray matter and contains the pontine reticular formation (which is continous with the reticular formation of the medulla and midbrain) as well as several cranial nerve nuclei (see CN nuclei of pons) and their associated tracts. In the basis pontis, islands of gray matter, the pontine nuclei, are interspersed amongst massive numbers of horizontally oriented pontocerebellar fibres and vertically oriented corticopontine, corticospinal and corticobulbar fibres. The pontocerebellar fibres continue laterally as the middle cerebellar peduncle, visible on the ventral surface of the pons. The ascending somatosensory pathways, the medial lemniscus and the spinothalamic tract (referred to collectively at this level as the spinal lemniscus) lie in the dorsal part of the basis pontis, adjacent to the tegmentum. A list of the major tracts present in cross sections of the pons are listed on another card (tracts of pons).
