  1. sigmoid sinus

    The sigmoid sinus is a venous sinus (a venous channel that drains blood from the brain) located in the cranium, specifically in the posterior part of the skull. Its name derives from its S-like shape. The sigmoid sinus is responsible for draining blood from the brain's lateral surfaces, and this structure usually extends from the area behind the ear to the base of the skull, where it connects with the internal jugular vein.


  1. Sigmoid sinus

    The sigmoid sinuses, within the human head, are two areas beneath the brain which allow blood to drain inferiorly from the posterior center of the head. They drain from the transverse sinuses and converge with the inferior petrosal sinuses to form the internal jugular vein. See diagram: labeled under the brain as "PARS SIGMOID.". Each sigmoid sinus begins beneath the temporal bone and follows a tortuous course to the jugular foramen, at which point the sinus becomes continuous with the internal jugular vein.
