| tegmentum of rhombencephalon | The portion of the pons continuous with the mesencephalic tegmentum; it consists of reticular formation, tracts, and cranial nerve nuclei, and forms the dorsal part of the pons (pars dorsalis pontis). Synonym: tegmentum rhombencephali, tegmentum of rhombencephalon. (05 Mar 2000) |

| ventricle of rhombencephalon | A cavity of irregular tentlike shape extending from the obex rostralward to its communication with the sylvian aqueduct, enclosed between the cerebellum dorsally and the rhombencephalic tegmentum ventrally, having a rhomboid-shaped floor (rhomboid fossa) and a tentlike roof which in its caudal part is formed by the tela choroidea and the posterior medullary velum, in its middle part by the white matter of the cerebellum, and in its narrowing rostral part (recessus superior) by the anterior medullary velum. The fourth ventricle reaches its greatest width at the pontomedullary transition, where it expands laterally behind the cerebellar peduncles into the spoutlike lateral recess, and its greatest height at the fastigial recess, which reaches up into the cerebellar white matter. Direct communication of the brain's ventricle system and the subarachnoid space is established at the level of the fourth ventricle by a median opening in the tela choroidea, the medial aperture of Magendie's foramen, which opens into the cerebellomedullary cistern, and on both sides by the lateral aperture or foramen of Luschka, which connects the lateral recess with the interpeduncular cistern. Synonym: ventriculus quartus, ventricle of rhombencephalon. (05 Mar 2000) |

| rhombencephalon | That part of the brainstem constituting the medulla oblongata (myelencephalon) and pons (metencephalon). (12 Dec 1998) |
| mesencephalic tegmentum | That major part of the substance of the mesencephalon or midbrain that extends from the substantia nigra to the level of the cerebral aqueduct. Synonym: tegmentum mesencephali, tegmentum, midbrain tegmentum. (05 Mar 2000) |
| rhombencephalic tegmentum | The portion of the pons continuous with the mesencephalic tegmentum; it consists of reticular formation, tracts, and cranial nerve nuclei, and forms the dorsal part of the pons (pars dorsalis pontis). Synonym: tegmentum rhombencephali, tegmentum of rhombencephalon. (05 Mar 2000) |

| tegmentum of pons | The part of the pons bounded laterally by the middle cerebellar peduncles and anteriorly by the ventral part of pons; it is continuous with the tegmentum of the mesencephalon and contains long tracts such as the medial and lateral lemnisci, cranial nerve nuclei, and reticular formation. Synonym: pars dorsalis pontis, tegmentum of pons. (05 Mar 2000) |
