| recessus ileocaecalis superior | A shallow pouch occasionally existing between the terminal ileum, the caecum, and the ileocolic artery when the latter is present. Synonym: recessus ileocaecalis superior. (05 Mar 2000) |
| recessus membranae tympani superior | A space in the mucous membrane on the inner surface of the tympanic membrane between the flaccid part of the membrane and the neck of the malleus. Synonym: recessus membranae tympani superior, Prussak's pouch, Prussak's space. (05 Mar 2000) |
| recessus superior omentalis | A portion of the vestibule of the bursa omentalis that extends upward between the inferior vena cava and the oesophagus. Synonym: recessus superior omentalis. (05 Mar 2000) |
| paries superior orbitae | Formed by the orbital plate of the frontal bone and the lesser wing of the sphenoid bone, the optic canal opens at its posterior limit; an indentation, the fossa for the lacrimal gland, is located in the anterolateral part of the roof. Synonym: paries superior orbitae, superior wall of orbit. (05 Mar 2000) |
| pars lateralis rami lobi medii venae pulmonalis dexter superior | lateral part of middle lobar branch of right superior pulmonary vein |

| pars superior faciei diaphragmaticae hepatis | The convex superior portion of the diaphragmatic surface of the liver. Synonym: pars superior faciei diaphragmaticae hepatis. (05 Mar 2000) |
| pars superior ganglii vestibularis | Rostral part, the superior part of the vestibular ganglion that receives fibres from the maculae of the utricle and the saccule and the ampullae of the anterior and lateral saemicircular ducts. Synonym: pars superior ganglii vestibularis. (05 Mar 2000) |
| pars superior rami lingularis venae pulmonis sinistri | <anatomy, vein> The vein that drains the superior lingular bronchopulmonary segment of the left lung. Synonym: pars superior rami lingularis venae pulmonis sinistri. (05 Mar 2000) |

| pedunculus cerebellaris superior | A large bundle of nerve fibres that originate from the dentate and interpositus nuclei and emerges from the cerebellum in the rostral direction, along the lateral wall of the fourth ventricle. The bundle submerges from the dorsal surface of the brainstem into the mesencephalic tegmentum, where all of its fibres cross in the massive decussation of the superior cerebellar peduncles. Part of the bundle terminates in the contralateral red nucleus; the bulk of the fibres continue rostrally to parts of the ventral intermediate nucleus of thalamus, ventral posterolateral nucleus of thalamus, and central lateral nucleus of thalamus. Synonym: pedunculus cerebellaris superior, brachium conjunctivum cerebelli. (05 Mar 2000) |
| gray layer of superior colliculus | Term applied to any one of the three major layers of gray matter of the superior colliculus that alternate with layers composed chiefly of nerve fibres: 1) the superficial gray layer of superior colliculus, above the largely white layer of the incoming fibres of the optic tract (optic layer); 2) the middle gray layer of superior colliculus, placed between the optic layer and a more deeply located layer of fibres, the stratum lemnisci; 3) the deep gray layer of superior colliculus, between the stratum lemnisci and the central gray substance surrounding the cerebral aqueduct, and containing the large nerve cells from which most of the colliculus descending connections (tectobulbar, tectopontine, and tectospinal tract) originate. Synonym: stratum griseum colliculi superioris, stratum cinereum colliculi superioris. (05 Mar 2000) |
