Sigmoid Sinus

The Sigmoid Sinus (pronunciation: /ˈsɪɡ.mɔɪd/ /ˈsaɪ.nəs/) is a dural venous sinus of the human body that plays a crucial role in the drainage of blood from the brain.

Etymology

The term "Sigmoid" is derived from the Greek word "σίγμα" (sigma), which means 'curved like the letter S'. The term "Sinus" is derived from the Latin word "sinus", which means 'bend or bay'.

Anatomy

The Sigmoid Sinus begins near the posterior inferior angle of the parietal bone, and its grooves are found in the posterior cranial fossa. It continues from the transverse sinus, runs forward and downward, and ultimately becomes the internal jugular vein.

Function

The primary function of the Sigmoid Sinus is to drain oxygen-depleted blood from the brain's posterior regions. It also facilitates the drainage of the cerebrospinal fluid when it is reabsorbed into the bloodstream.
