trans·verse si·nus

[TA]
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(s): sinus transversus [TA], lateral sinus

transverse sinus

one of a pair of large venous channels in the posterior superior group of sinuses serving the dura mater, draining into the sigmoid sinuses, then the internal jugular vein. Compare confluence of the sinuses, inferior sagittal sinus, occipital sinus, straight sinus, superior sagittal sinus.

(trans-vĕrs' sī'nŭs) [TA]
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.

transverse sinus

A dural sinus in the lateral edge of the tentorium cerebelli along each lateral upper border of the posterior cranial fossa. One transverse sinus (usually the right) is a continuation of the superior sagittal sinus; the other transverse sinus (typically the smaller of the two) is the continuation of the inferior sagittal sinus, although both transverse sinuses usually have a connection near their origin, in the region of the confluence of sinuses. The transverse sinuses run anteriorly and turn downward to become the sigmoid sinuses at the front edges of the tentorium cerebelli; at this point, the transverse sinuses are joined by the superior petrosal sinuses. Tributaries of the transverse sinuses include inferior cerebral, inferior cerebellar, and diploic veins.
