|---|---|
| groove for transverse sinus | The groove on the inner surface of the occipital bone marking the course of the transverse sinus; the tentorium is attached to its margins. Synonym: sulcus sinus transversi, sulcus for transverse sinus. (05 Mar 2000) |
| midgastric transverse sphincter | Angular sphincter, thickening of the circular muscular layer forming a proposed intermediate sphincter at the level of the angular notch of the stomach. While the thickening of the circular muscle may indicate the commencement of the pyloric antrum, true functional sphincteric activity distinct from the other peristaltic contractions of the stomach is not observed although some of these may in fact temporarily close off the antrum from the remainder of the stomach lumen. Synonym: antral sphincter, midgastric transverse sphincter, sphincter antri, sphincter intermedius, sphincter of antrum, sphincter of gastric antrum. (05 Mar 2000) |
| myelitis, transverse | Myelitis in which the functional effect of the lesions spans the width of the entire cord at a given level. (12 Dec 1998) |
| costal pit of transverse process | A facet on the transverse process of a vertebra for articulation with the tubercle of a rib. Synonym: fovea costalis processus transversi, costal pit of transverse process. (05 Mar 2000) |
| sulcus for transverse sinus | The groove on the inner surface of the occipital bone marking the course of the transverse sinus; the tentorium is attached to its margins. Synonym: sulcus sinus transversi, sulcus for transverse sinus. (05 Mar 2000) |
| superficial branch of the transverse cervical artery | <anatomy, artery> Branch of transverse cervical artery which accompanies the spinal accessory nerve on the deep surface of the trapezius muscle. Alternatively arises as a direct branch of the thyrocervical trunk, in which case it is called the superficial cervical artery. (05 Mar 2000) |
| superficial transverse metacarpal ligament | <anatomy> A thickening of the deep fascia in the most distal part of the (base) of the triangular palmar aponeurosis. Synonym: ligamentum metacarpale transversum superficiale, Gerdy's fibres, ligamentum natatorium. (05 Mar 2000) |
| superficial transverse metatarsal ligament | <anatomy> A thickening of the distal part (base) of the plantar aponeurosis, at the level of the heads of the metatarsal bones. Synonym: ligamentum metatarsale transversum superficiale. (05 Mar 2000) |
| superficial transverse muscle of perineum | <anatomy> An inconstant muscle; origin, ramus of ischium; insertion, central tendon of perineum; action, draws back and fixes the central tendon of the perineum; nerve supply, pudendal (perineal). Synonym: musculus transversus perinei superficialis, superficial transverse muscle of perineum, Theile's muscle. (05 Mar 2000) |
| superficial transverse perineal muscle | <anatomy> An inconstant muscle; origin, ramus of ischium; insertion, central tendon of perineum; action, draws back and fixes the central tendon of the perineum; nerve supply, pudendal (perineal). Synonym: musculus transversus perinei superficialis, superficial transverse muscle of perineum, Theile's muscle. (05 Mar 2000) |
| superior branch of the transverse cervical nerve | <anatomy, nerve> Branch providing cutaneous innervation in upper part of anterior triangle of neck. Synonym: ramus superior nervi transversalis cervicalis (colli). (05 Mar 2000) |
| superior transverse scapular ligament | <anatomy> The strong fibrous band that bridges the scapular notch creating a foramen that gives passage to the suprascapular nerve, while the suprascapular vessels pass over the ligament superiorly. Synonym: ligamentum transversum scapulae superius, suprascapular ligament. (05 Mar 2000) |
| deep branch of the transverse cervical artery | <anatomy, artery> Origin, subclavian or as the deep branch of the transverse cervical; distribution, passes deep to the rhomboid muscles, supplying them and other muscles and skin along the vertebral border of the scapula; anastomoses, suprascapular and scapular circumflex. Synonym: arteria dorsalis scapulae, rami profundi arteriae transversae cervicis, ramus profundus arteriae transversae colli, arteria scapularis dorsalis, arteria scapularis descendens, deep branch of the transverse cervical artery, descending scapular artery, ramus profundus arteria scapularis descendens. (05 Mar 2000) |
| deep transverse metacarpal ligament | <anatomy> The ligament that interconnects the palmar surface of the heads of the second to fifth metacarpals, being continuous with the palmar ligaments on palmar plates; it lies in the plane of the palmar interosseous fascia. Synonym: ligamentum metacarpale transversum profundum, transverse metacarpal ligament. (05 Mar 2000) |
