The equine dorsal sinus system of the dura mater develops from the dural venous plexuses. In early development, venous blood from these plexuses is drained into the primary head vein, which together with the stem of the caudal dural plexus joins the primitive internal jugular vein. After involution of the primary head vein new channels, the transverse and sigmoid sinuses, develop which empty into the internal jugular vein. The temporal sinus develops secondarily and coexists with the sigmoid sinus. After regression of the sigmoid sinus and internal jugular vein, the temporal sinus represents the sole channel in the equine fetuses, by which venous blood from the brain is drained through the emissary vein of the retroarticular foramen into the external jugular system.
