Sinus Dura

The sinus of the dura mater (lat. sinus durae matris, pna, bna, jna; synonym - sinus of the dura mater) is the venous vessels of the dura mater, located between its outer and inner layers. They collect blood from the veins of the brain and drain it into the internal jugular vein.

The main sinuses of the dura mater:

  1. The superior sagittal sinus is located along the falciform process and collects blood from the upper parts of the brain.
  2. The transverse sinus connects the sagittal sinus with the sigmoid sinus.
  3. The sigmoid sinus drains blood from the occipital and temporal lobes of the brain.
  4. The inferior sagittal sinus receives blood from the lower parts of the brain.
  5. The straight sinus connects the sagittal sinus with the cavernous sinus.

Thus, the sinuses of the dura mater form a system of venous vessels that ensure the outflow of blood from the cranial cavity. Violation of their patency is fraught with the development of intracranial hypertension and cerebral edema.



The dural sinus is an anatomical structure that is located in the brain and plays an important role in its functioning. According to the scientific literature, it has complex morphological features and is connected to other important brain structures. This article describes the blue dura mater and its connection to the brain.

The dural sinus is a small anatomical structure measuring several centimeters in diameter. It is located near the nasal surface of the brain and is in contact with the sinuses coming from the middle ear. However, despite its modest location, the sinus plays a very important role in the functioning of the brain. In fact, it is a cavity filled with fluid, which increases the volume of the brain and improves its shock absorption. Also, thanks to the sinus of the dura mater, intracranial pressure is regulated, and gases are exchanged between blood and air. In addition, this area is a source of pathological processes such as abscesses and meningitis. In general, the dural sinus is of significant importance for normal human functioning and should be well studied to avoid possible complications when working with this anatomical area.
