The myelencephalon is a developmental categorization of a portion of the central nervous system. ... Position of medulla oblangata in the human brain The medulla oblongata is the lower portion of the brainstem. ... Grays Fig. ... The solitary nucleus and tract are structures in the brainstem that carry and receive visceral sensation and taste from the facial (VII), glossopharyngeal (IX), vagus (X) cranial nerves, as well as the cranial part of the accessory nerve (XI). ... The hypoglossal nerve is the twelfth cranial nerve. ... The nucleus ambiguus is a cranial nerve nucleus, located in the medulla oblongata, and handles the branchial motor functions of the ninth (glossopharyngeal) and tenth (vagus) cranial nerves. ... In anatomy, the olivary bodies or simply olives (Latin oliva) are a pair of prominent oval structures in the medulla oblongata, the lower portion of the brainstem. ... Cuneate nucleus is a wedge-shaped nucleus in the medulla. ...

METENCEPHALON/CEREBELLUM: cerebellar vermis, flocculus, arbor vitae The metencephalon is a developmental categorization of portions of the central nervous system. ... Figure 1a: A human brain, with the cerebellum in purple. ... Part of the structure of animal brains, the cerebellar vermis is a narrow, wormlike structure between the hemispheres of the cerebellum. ... The flocculus is a small lobe of the cerebellum at the posterior border of the middle cerebellar peduncle anterior to the biventer lobule; it is associated with the nodulus of the vermis; together, these two structures compose the vestibular part of the cerebellum. ... The arbor vitae (Tree of Life) refers to the cerebellar white matter, so called for its branched, tree-like appearance. ...

METENCEPHALON/PONS: pontine tegmentum, trapezoid body, pontine nuclei (superior olivary nucleus, trigeminal nerve nuclei, abducens nucleus, facial nucleus, cochlear nuclei, vestibular nuclei), locus ceruleus, paramedian pontine reticular formation, nucleus centralis superior The metencephalon is a developmental categorization of portions of the central nervous system. ... Position of the pons in the human brain The pons (sometimes pons Varolii after Costanzo Varolio) is a knob on the brain stem. ... The pontine tegmentum is a part of the pons of the brain involved in the initiation of REM sleep. ... The trapezoid body is part of the acoustic pathway. ... The pontine nuclei are a part of the pons which store the memory of intention during motor activity. ... // Anatomy The superior olivary nucleus (or superior olive) is a small mass of gray substance situated on the dorsal surface of the lateral part of the trapezoid body. ... The abducens nucleus is the originating nucleus from which the abducens nerve emerges. ... The cochlear nuclei consist of: (a) the lateral cochlear nucleus, corresponding to the tuberculum acusticum on the dorso-lateral surface of the inferior peduncle; and (b) the ventral or accessory cochlear nucleus, placed between the two divisions of the nerve, on the ventral aspect of the inferior peduncle. ... The Locus ceruleus, also spelled locus coeruleus, (Latin for the blue bit) is a nucleus in the brain stem (under the cerebellum in the caudal midbrain/rostral pons) apparently responsible for the physiological reactions involved in stress and panic. ... The paramedian pontine reticular formation, or PPRF, is a brain region, without clearly defined borders, in the center of the pons. ...

FOURTH VENTRICLE: obex, median aperture The fourth ventricle is one of the four connected fluid-filled cavities within the human brain. ... IrOBEX (or just OBEX) is a communications protocol that facilitates the exchange of binary objects between devices. ... The Median Aperture of the brain (apertura medialis ventriculi quarte) or Foramen of Magendie is an opening in the hollow nerve tube, connecting the 4th ventricle of the brain with the subarachnoid space The median aperture along with the paired lateral apertures (foramina of Luschka) are the primary routes for...
