| nervus gluteus superior | <anatomy, nerve> Arises from the fourth and fifth lumbar and first sacral nerves, and supplies the gluteus medius and minimus and tensor fasciae latae muscles (abductors and medial rotators of the hip joint). A lesion of this nerve causes the pelvis to drop on the unsupported side when the foot is lifted off the ground (Trendelenburg sign). Synonym: nervus gluteus superior. (05 Mar 2000) |

Synonym: nervus laryngeus superior. (05 Mar 2000) |

| sulcus frontalis superior | A sagittal fissure on the superior surface of each frontal lobe of the cerebrum starting from the precentral sulcus; it forms the lateral boundary of the superior frontal convolution. Synonym: sulcus frontalis superior. (05 Mar 2000) |
| sulcus occipitalis superior | One of several small and variable sulci bordering the superior occipital gyri on the upper aspect of the occipital lobe of the cerebrum. Synonym: sulcus occipitalis superior. (05 Mar 2000) |
| sulcus temporalis superior | The longitudinal sulcus that separates the superior and middle temporal gyri. Synonym: sulcus temporalis superior, superior temporal fissure. (05 Mar 2000) |
| nucleus centralis tegmenti superior | One of the nuclei raphes. Synonym: Bechterew's nucleus. (05 Mar 2000) |
| nucleus salivatorius superior | A group of preganglionic parasympathetic motor neurons situated rostral and lateral to the inferior salivatory nucleus; it governs secretion of the lacrimal, sublingual, and submaxillary glands by way of the facial nerve and the sphenopalatine and submandibular ganglia. Synonym: nucleus salivatorius superior, superior salivary nucleus. (05 Mar 2000) |
| nucleus sensorius superior nervi trigemini | <anatomy, nerve> The term commonly used to designate the nucleus pontis nervi trigeminalis; located in pons lateral to the motor trigeminal nucleus; receives primary sensory (touch and pressure) input via the trigeminal nerve, projects to ventral posteromedial nucleus of thalamus. Synonym: nucleus sensorius principalis nervi trigemini, nucleus sensorius superior nervi trigemini, principal sensory nucleus of the trigeminus. (05 Mar 2000) |
| superficial branch of the superior gluteal artery | <anatomy, artery> To upper gluteus maximus muscle. Synonym: ramus superficialis arteriae gluteae superioris. (05 Mar 2000) |

| superior | <anatomy> Situated above another structure. <plant biology> Of an ovary, borne above the level of attachment of the other floral parts, or above the base of a cup (hypanthium) that is free from the ovary and bears the perianth segments and stamens. Compare: inferior. (09 Oct 1997) |
| superior aberrant ductule | A diverticulum from the head of the epididymis. Synonym: ductulus aberrans superior. (05 Mar 2000) |
| superior alveolar nerves | Three branches (posterior, middle, and anterior) of the maxillary nerve (or its continuation as the infraorbital nerve) that enter the maxilla to supply the mucosa of the maxillary sinus, upper teeth and gingiva. Synonym: nervi alveolares superiores, superior dental nerves. (05 Mar 2000) |
| superior anastomotic vein | <anatomy, vein> A large communicating vein between the superficial middle cerebral vein and the superior sagittal sinus; it passes upward from the lateral sulcus, often following the line of the central sulcus (Rolando's fissure). Synonym: vena anastomotica superior, Trolard's vein. (05 Mar 2000) |
