| superior border of petrous part of temporal bone | The margin that separates the anterior and posterior surfaces of the petrous part of the temporal bone and the lateral part of the middle cranial fossa from the posterior cranial fossa. Synonym: margo superior partis petrosae ossis temporalis, crest of petrous part of temporal bone. (05 Mar 2000) |
| superior part of diaphragmatic surface of liver | The convex superior portion of the diaphragmatic surface of the liver. Synonym: pars superior faciei diaphragmaticae hepatis. (05 Mar 2000) |
| superior part of duodenum | superior part of duodenum |
| superior part of lingular branch of left pulmonary vein | <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) |
| superior part of vestibular ganglion | 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) |
| superior part of vestibulocochlear nerve | <anatomy, nerve> The vestibular part of the acoustic (8th cranial) nerve. The vestibular nerve fibres arise from neurons of scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the vestibular nuclei of the brainstem. These fibres mediate the sense of balance and head position. (12 Dec 1998) |

| deep part of flexor retinaculum | <anatomy> A strong fibrous band crossing the front of the carpus and binding down the flexor tendons of the digits and the flexor carpi radialis tendon and the median nerve; in so doing it creates the carpal tunnel. Synonym: retinaculum flexorum, deep part of flexor retinaculum, flexor retinaculum, ligamentum carpi transversum, ligamentum carpi volare, volar carpal ligament. (05 Mar 2000) |

| deep part of parotid gland | See: parotid gland. (05 Mar 2000) |
| supraclavicular part of brachial plexus | The part of the brachial plexus, including the roots, trunks, and divisions, that gives rise to the dorsal scapular, long thoracic, suprascapular and subclavian nerves. Synonym: pars supraclavicularis plexus brachialis. (05 Mar 2000) |
| sympathetic part | <anatomy, physiology> One of the two divisions of the vertebrate autonomic nervous system (the other being the parasympathetic nervous system). The sympathetic preganglionic neurons have their cell bodies in the thoracic and lumbar regions of the spinal cord and connect to the paravertebral chain of sympathetic ganglia. Innervate heart and blood vessels, sweat glands, viscera and the adrenal medulla. most sympathetic neurons, but not all, use noradrenaline as a post ganglionic neurotransmitter. (19 Jan 1998) |
| descending part of aorta | A part of the aorta, further divided into the thoracic aorta and the abdominal aorta. Synonym: pars descendens aortae, aorta descendens, descending part of aorta. (05 Mar 2000) |
