| transverse tarsal joint | The synovial joints between the talus and navicular bone medially and the calcaneus and navicular bones laterally which act as a unit in allowing the front of the foot to pivot relative to the back of the foot about the longitudinal axis of the foot, contributing to the total inversion and eversion movements. Synonym: articulatio tarsi transversa, Chopart's joint, midtarsal joint, transverse tarsal articulation. (05 Mar 2000) |

| transverse temporal convolutions | Two or three convolutions running transversely on the upper surface of the temporal lobe bordering on the lateral (sylvian) fissure, separated from each other by the transverse temporal sulci. Synonym: gyri temporales transversi, Heschl's gyri, transverse temporal convolutions. (05 Mar 2000) |
| transverse temporal gyri | Two or three convolutions running transversely on the upper surface of the temporal lobe bordering on the lateral (sylvian) fissure, separated from each other by the transverse temporal sulci. Synonym: gyri temporales transversi, Heschl's gyri, transverse temporal convolutions. (05 Mar 2000) |
| transverse temporal sulci | The shallow sulci that demarcate the transverse temporal gyri on the opercular surface of the superior temporal gyrus. Synonym: sulci temporales transversi. (05 Mar 2000) |
| transverse tibiofibular ligament | <anatomy> The distal continuation of the interosseous membrane forming a strong ligament that unites the distal end of the tibia and fibula; it lies deep to the posterior tibiofibular ligament. Synonym: interosseous tibiofibular ligament. (05 Mar 2000) |
| transverse tubule | <cell biology> Invagination of the plasma membrane (sarcolemma) of striated muscle that lies between two tubular portions of the endoplasmic (sarcoplasmic) reticulum to form a triad of membrane profiles adjacent to the A band/I band junction in some cases, in other cases to the Z disc, of the resting sarcomere. Depolarisation of the T tubule membrane triggers the release of calcium from the sarcoplasmic reticulum and eventually muscle contraction. (18 Nov 1997) |
| transverse vein of face | <anatomy, vein> A tributary of the superficial temporal or retromandibular veins, anastomosing with the facial vein. Synonym: vena transversa faciei, transverse vein of face. (05 Mar 2000) |
| transverse vein of scapula | <anatomy, vein> Vein that accompanies the suprascapular artery and empties into the external jugular vein. Synonym: vena suprascapularis, transverse vein of scapula, vena transversa scapulae. (05 Mar 2000) |
| transverse veins of neck | Venae comitantes of the corresponding arteries, emptying into the external jugular vein or sometimes into the subclavian vein. Synonym: venae transversae colli, transverse veins of neck. (05 Mar 2000) |
| transverse velum | A fold in the dorsal wall of the embryonic brain at the boundary between the telencephalon and diencephalon. Synonym: velum transversum. (05 Mar 2000) |
| transverse vesical fold | A duplication of peritoneum passing over the empty bladder, but obliterated when the viscus is full. Synonym: plica vesicalis transversa. (05 Mar 2000) |
| transverse wave | <radiobiology> Waves in which the direction of the oscillation is perpendicular (transverse) to the direction of the wave propagation. Examples include plucked strings and electromagnetic waves in free space or air. (09 Oct 1997) |
| foramen of transverse process | Foramen processus transversus. Synonym: foramen processus transversi, foramen transversarium, foramen vertebroarterialis, foramen of transverse process, vertebroarterial foramen. (05 Mar 2000) |
| abdominal external oblique muscle | <anatomy, muscle> Origin, fifth to twelfth ribs; insertion, anterior half of lateral lip of iliac crest, inguinal ligament, and anterior layer of the rectus sheath; action, diminishes capacity of abdomen, draws thorax downward; nerve supply, thoracoabdominal nerves. Synonym: musculus obliquus externus abdominis, abdominal external oblique muscle. (05 Mar 2000) |
| abdominal internal oblique muscle | <anatomy, muscle> Origin, iliac fascia deep to lateral part of inguinal ligament, anterior half of crest of ilium, and lumbar fascia; insertion, tenth to twelfth ribs and sheath of rectus; some of the fibres from inguinal ligament terminate in the conjoint tendon; action, diminishes capacity of abdomen, flexes lumbar vertebral column (bends thorax forward); nerve supply, lower thoracic. Synonym: musculus obliquus internus abdominis, abdominal internal oblique muscle. (05 Mar 2000) |
