Superior Sagittal Sinus

The Superior Sagittal Sinus (pronunciation: su·pe·ri·or sa·git·tal si·nus) is a significant dural venous sinus located in the human brain.

Etymology

The term "Superior Sagittal Sinus" is derived from Latin. "Superior" means upper, "sagittal" refers to the sagittal plane that divides the body into left and right halves, and "sinus" in this context refers to a channel for venous blood.

Anatomy

The Superior Sagittal Sinus is an unpaired area of the dural venous sinuses, which drain blood from the brain towards the heart. It runs along the attached margin of the falx cerebri, a sickle-shaped fold of the dura mater in the brain. The sinus receives blood from the superficial cerebral veins and drains into the confluence of sinuses, also known as the torcular Herophili.

Function

The primary function of the Superior Sagittal Sinus is to drain the deoxygenated blood from the brain's superficial veins into the transverse sinuses. It also facilitates the circulation of the cerebrospinal fluid.
