| superficial lingual muscle | An intrinsic muscle of the tongue, running from base to tip on the dorsum just beneath the mucous membrane; action, shortens the upper part of the tongue; nerve supply, motor by hypoglossal, sensory by lingual. Synonym: musculus longitudinalis superior, superficial lingual muscle. (05 Mar 2000) |

| superficial lymphatic vessel | One of the lymphatic vessels that lie in the skin and subcutaneous tissues; they join the deep lymphatic vessels. Synonym: vas lymphaticum superficiale. (05 Mar 2000) |
| superficial middle cerebral vein | <anatomy, vein> A large vein passing along the line of the sylvian fissure to join the cavernous sinus; it communicates with the superior sagittal sinus and transverse sinus via the superior and inferior anastomotic veins, respectively. Synonym: vena cerebri media superficialis. (05 Mar 2000) |
| superficial palmar (arterial) arch | The arterial arch in the hand located superficial to the long flexor tendons approximately at the level of a line extrapolated across the palm from the distal side of the outstretched thumb. It is formed principally by the termination of the superficial ulnar artery and is usually completed by a communication with the superficial palmar branch of the radial artery. The arch gives rise to the common palmar digital arteries. Synonym: arcus palmaris superficialis, arcus volaris superficialis. (05 Mar 2000) |
| superficial palmar artery | <anatomy, artery> The superficial palmar branch of the radial artery which supplies the thenar muscles then enters the palm to communicate with the superficial palmar arch from the ulnar artery. Synonym: ramus palmaris superficialis arteriae radialis, superficial palmar artery, superficial volar artery, superficialis volae. (05 Mar 2000) |
| superficial palmar branch of radial artery | <anatomy, artery> The superficial palmar branch of the radial artery which supplies the thenar muscles then enters the palm to communicate with the superficial palmar arch from the ulnar artery. Synonym: ramus palmaris superficialis arteriae radialis, superficial palmar artery, superficial volar artery, superficialis volae. (05 Mar 2000) |
| superficial palmar venous arch | The venous arch accompanying the superficial palmar arterial arch it consists usually of paired venae comitantes and is drained by the superficial ulnar and radial veins. Synonym: arcus venosus palmaris superficialis. (05 Mar 2000) |
| superficial parotid lymph nodes | Several small lymph nodes located in the subcutaneous tissue in the parotid region. Synonym: nodi lymphatici parotidei superficiales. (05 Mar 2000) |

| superficial perineal pouch | The superficial compartment of the perineum; the space bounded above by the perineal membrane (inferior fascia of the urogenital diaphragm) and below by the superficial perineal (Colles') fascia; it contains the root structure of the penis or clitoris and associated musculature, plus the superficial transverse perineal muscle and, in the female only, the greater vestibular glands. Synonym: spatium perinei superficiale, Colles' space, superficial perineal pouch. (05 Mar 2000) |

Synonym: spatium perinei superficiale, Colles' space, superficial perineal pouch. (05 Mar 2000) |
| superficial peroneal nerve | <anatomy, nerve> A branch of the common peroneal nerve which passes downward in the lateral compartment of the leg to supply the peroneus longus and brevis muscles and terminate as the intermediate and medial dorsal cutaneous nerves supplying the skin of the dorsum of the foot and toes (except for adjacent sides of great and second toes). Synonym: nervus fibularis superficialis, nervus peroneus superficialis, musculocutaneous nerve of leg, superficial fibular nerve. (05 Mar 2000) |
