Dural venous sinuses are a group of venous channels located within the dura mater, the membrane that encases the brain and spinal cord. These sinuses are responsible for draining blood from the brain and delivering it to the internal jugular veins, which lead to the heart. There are several synonyms for dural venous sinuses, including: cerebral sinuses, intracranial sinuses, meningeal sinuses, cavernous sinuses, lateral sinuses, sagittal sinuses, and transverse sinuses. These synonyms are often used interchangeably, but they refer to the same anatomical structures that play a crucial role in maintaining proper blood flow within the brain.
