| superficial volar 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) |
| ulnar communicating branch of superficial radial nerve | <anatomy, nerve> Ulnar communicating branch of superficial branch of radial nerve, joining the dorsal branch of the ulnar nerve in the hand conveying sensation from the dorsal aspect of adjacent sides of the middle and ring fingers. Synonym: ramus communicans ulnaris nervi radialis. (05 Mar 2000) |
| lateral crus of the superficial inguinal ring | Portion of the external oblique aponeurosis which passes lateral to the superficial inguinal ring blending into the inguinal ligament and forming the lateral boundary of the ring. Synonym: crus laterale anuli inguinalis superficialis. (05 Mar 2000) |
| lateral superficial cervical lymph nodes | One to four nodes lying along the external jugular vein; they drain the skin and superficial structures over the region of the sternocleidomastoid muscle and send efferent vessels to the deep lateral cervical lymph nodes. Synonym: nodi lymphatici cervicales laterales superficiales. (05 Mar 2000) |
| frontal branch of superficial temporal artery | <anatomy, artery> Terminal branch of superficial temporal artery (with parietal branch) supplying anterolateral scalp and underlying musculature, periosteum, and outer table of cranium; anastomosis: across midline with contralateral partner; supratrochlear and supraorbital arteries. Synonym: ramus frontalis arteriae temporalis superficialis. (05 Mar 2000) |
| lesser superficial petrosal nerve | <anatomy, nerve> The parasympathetic root of the otic ganglion, derived from the tympanic plexus; it leaves the tympanic cavity through the canal for the lesser petrosal nerve and passes within the cranium to the sphenopetrosal fissure, or to the foramen ovale, or to the petrosal foramen through which it descends to reach the otic ganglion; conveys presynaptic parasympathetic fibres from the glossopharyngeal nerve concerned with secretomotor innervation of the perotid gland. Synonym: nervus petrosus minor, lesser petrosal nerve. (05 Mar 2000) |

| anal fascia | The fascia that covers the inferior aspect of the levator ani and coccygeus muscles. Synonym: fascia diaphragmatis pelvis inferior, anal fascia. (05 Mar 2000) |
| antebrachial fascia | It is continuous with the brachial fascia; in the region of the wrist it forms two thickened bands, the extensor and flexor retinacula. Synonym: fascia antebrachii, deep fascia of forearm, fascia of forearm. (05 Mar 2000) |
| arcus tendineus of obturator fascia | <anatomy> A thickened portion of the obturator fascia that extends in an arching line from the pubis posteriorly to the ischial spine and gives origin to part of the levator ani muscle. Synonym: arcus tendineus musculi levatoris ani, arcus tendineus of obturator fascia. (05 Mar 2000) |
| axillary fascia | The fascia that forms the floor of the axilla. It is continuous with the pectoral and clavipectoral fascia anteriorly, with the brachial fascia laterally, and with the fascia of the latissimus dorsi and serratus anterior muscles posteriorly and medially. Synonym: fascia axillaris. (05 Mar 2000) |
| bicipital fascia | Aponeurosis bicipitalis, radiating fibres from the tendon of insertion of the biceps which form a triangular band passing obliquely across the hollow of the elbow to the ulnar side and becoming merged into the deep fascia of the forearm. Formerly called "grace Dieu" fascia, it serves to protect the brachial artery and median nerve during phlebotomy of median cubital vein. Synonym: aponeurosis musculi bicipitis brachii, bicipital fascia, lacertus fibrosus, semilunar fascia. (05 Mar 2000) |
