| transverse section | A cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body structure, in a horizontal plane, i.e., a plane which intersects the longitudinal axis at a right angle. Since actual sectioning in the transverse plane results in an inferior and a superior portion, an anatomical transverse section may be a two-dimensional view of the cut surface on the inferior aspect of the superior portion, or of the superior aspect of the inferior portion. By convention, in medical imaging transverse sections demonstrate the former unless otherwise stated. Synonym: axial section. (05 Mar 2000) |

| transverse septum | The mesodermal mass separating the pericardial and peritoneal cavities; it is covered with mesothelium except where intimately associated with the liver which originally develops within it; the septum is definitively incorporated into the diaphragm as the central tendon. (05 Mar 2000) |
| transverse sinus | A paired dural venous sinus that drains the confluence of sinuses, running along the occipital attachment of the tentorium cerebelli and terminating in the sigmoid sinus. Synonym: sinus transversus, lateral sinus. Transverse pericardial sinus, a passage in the pericardial sac between the origins of the great vessels, i.e., posterior to the intrapericardial portions of the pulmonary trunk and ascending aorta and anterior to the superior vena cava and superior to the atria; it is formed as a result of the flexure of the heart tube, partially approximating the great venous and arterial vessels. Synonym: sinus transversus pericardii, Theile's canal, transverse sinus of pericardium. (05 Mar 2000) |
| transverse sinus of pericardium | transverse pericardial sinus |
| transverse tarsal articulation | 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: 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 myelitis |
An acute attack of inflammatory demyelination that involves both sides of the spinal cord. The spinal cord loses its ability to transmit nerve impulses up and down. Paralysis and numbness are experienced in the legs and trunk below the level of the inflammation.

| transverse |
Usually referring to the position of the fetus within the uterus. Sometimes babies will become positioned horizontally across the uterus, instead of the vertical position with the head or buttocks pointing toward the cervix. Usually the fetus will orient himself properly before labor. If the baby cannot be properly oriented, a C-section may be needed.

Describes the side-lying (where the baby's body length is horizontal in the uterus) position of the baby before birth. Unless moved, the baby will have to be delivered by c-section.
