| spina iliaca anterior superior | The anterior extremity of the iliac crest, which provides attachment for the inguinal ligament and the sartorius muscle. Synonym: spina iliaca anterior superior. (05 Mar 2000) |

| spina iliaca posterior superior | The posterior extremity of the iliac crest, the uppermost point of attachment of the sacrotuberous and posterior sacroiliac ligaments; a readily apparent dimple occurs in the skin overlying the posterior superior iliac spine which is clinically useful as an indication of the level of the S-2 vertebra, the level of the inferior limit of the subarachnoid space. Synonym: spina iliaca posterior superior. (05 Mar 2000) |
| nervus cardiacus cervicalis superior | <anatomy, nerve> The uppermost of the cardiopulmonary splanchnic nerves which arises from the lower part of the superior cervical ganglion and passes down to form, with branches of the vagus, the cardiac plexus. Synonym: nervus cardiacus cervicalis superior. (05 Mar 2000) |
| nervus cutaneus brachii lateralis superior | <anatomy, nerve> The terminal branch of the axillary nerve supplying the skin over the lower portion of the deltoid and for a distance below its insertion. Synonym: nervus cutaneus brachii lateralis superior, upper lateral cutaneous nerve of arm. (05 Mar 2000) |
| 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) |
| nervus laryngeus superior | <anatomy, nerve> A branch of the vagus nerve at the inferior ganglion; at the thyroid cartilage it divides into two branches; the internal laryngeal nerve, a sensory branch which supplies the mucous membrane of the larynx superior to the vocal folds, and the external laryngeal nerve, a motor branch which supplies the inferior pharyngeal constrictor and the cricothyroid muscle. Synonym: nervus laryngeus superior. (05 Mar 2000) |
| norma superior | The outline of the surface of the skull viewed from above. Synonym: norma 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 gray layer of superior colliculus | See: gray layer of superior colliculus. (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) |
