| sinus petrosus superior | A paired dural venous sinus in the groove along the crest of the petrous temporal bone, connecting the cavernous sinus with the termination of the transverse sinus or beginning of the sigmoid sinus. Synonym: sinus petrosus superior. (05 Mar 2000) |
|---|---|
| sinus sagittalis superior | An unpaired dural venous sinus in the sagittal groove, beginning at the foramen caecum and terminating at the confluence of sinuses where it merges with the straight sinus; receives the superior cerebral veins and has lateral extensions, the lateral venous lacunae. Synonym: sinus sagittalis superior, superior longitudinal sinus. Tarsal sinus, a hollow or canal formed by the groove of the talus and the interosseous groove of the calcaneus which is occupied by the interosseous talocalcaneal ligament. Synonym: sinus tarsi, tarsal canal. (05 Mar 2000) |
| skeleton of free superior limb | The bones of the upper limb except the scapula and clavicle, i.e., all upper limb bones including and distal to the humerus. (05 Mar 2000) |
| 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) |
| sternocleidomastoid branch of superior thyroid artery | <anatomy, artery> Branch of superior thyroid artery to sternocleidomastoid muscle. Synonym: ramus sternocleidomastoideus arteriae thyroideae superioris. (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) |
