| transverse plane | A plane across the body at right angles to the coronal and sagittal plane's. Synonym: horizontal plane. (05 Mar 2000) |
| transverse pontine fibres | Fibres arising from the pontine nuclei, decussate and pass into the cerebellum as the middle cerebellar peduncles. Synonym: fibrae pontis transversae. (05 Mar 2000) |

| transverse process | A bony protrusion on either side of the arch of a vertebra, from the junction of the lamina and pedicle, which functions as a lever for attached muscles. Synonym: processus transversus. (05 Mar 2000) |
| transverse rectal folds | The three or four crescentic folds placed horizontally in the rectal mucous membrane; the superior rectal fold is situated near the beginning of the rectum on the left side; the middle rectal fold (Nelaton's fold) is most prominent and consistent and projects from the right side about 8 cm above the anus (approximately the level of the floor of the rectouterine or rectovesical pouch); the inferior rectal fold is on the left side about 5 cm above the anus.

| 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) |
