Classification
Nouns denoting body parts.
Examples
- The sinus transversus is a paired dural sinus that collects blood from the confluence of sinuses and drains into the sigmoid sinus.
- Each sinus transversus is located within the tentorium cerebelli, near the junction of the falx cerebri and the tentorium.
- The sinus transversus is a major drainage pathway for the cerebral veins, terminating in the sigmoid sinus before emptying into the jugular veins.
- Anatomical variations in the sinus transversus can be associated with increased risk of dural arteriovenous fistulas, which can be treated with endovascular embolization.
- During neurosurgical procedures, the sinus transversus is often carefully preserved to avoid damaging the dural sinuses and compromising venous drainage.
