Intercavernous Sinuses

Intercavernosi sinuses (sinus intercavernosi, pna, jna) are a pair of sinuses located in the human head, at the base of the skull. They are located on either side of the sella turcica, which is the plate-shaped protrusion of the frontal bone.

Intercavernous sinuses are important for normal brain function. They are part of the circulatory system of the head and brain, and their function is to collect and drain blood from the brain. In addition, they play an important role in regulating intracranial pressure.

Each intercavernous sinus has the shape of a semicircular fissure, which is located between the bone of the base of the skull and the meninges. Inside the sinus are small valves that allow blood to flow freely in one direction, but prevent it from flowing back.

Pathologies of the intercavernous sinuses are rare, but can be serious. For example, thrombosis (blockage) of the intercavernous sinuses can lead to the development of a stroke or other circulatory disorders in the brain. In addition, lesions of the intercavernous sinuses may be symptoms of certain diseases, such as brain tumors or infections.

In conclusion, the intercavernous sinuses are an important part of the blood circulation of the head and brain. Their function is to collect and drain blood from the brain, as well as regulate intracranial pressure. Although pathologies of the intercavernous sinuses are rare, they can be serious and require careful attention from doctors.
