| 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) |

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.

| 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 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 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) |
