The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired dural venous sinus lying along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of the anterior cerebral hemispheres to the confluence of sinuses .
The walls of the dural venous sinuses are composed of dura mater lined with endothelium, a specialized layer of flattened cells found in blood and lymph vessels.They differ from other blood vessels in that they lack a full set of vessel layers (e.g. tunica media) characteristic of arteries and veins.
The confluence of sinuses shows significant variation. [1] Most commonly, there is a continuous connection between all of the sinuses. [1] [2] A very common variant is the superior sagittal sinus only draining into the right transverse sinus - more rarely, it may also only drain into the left transverse sinus.
The cheapest Super Bowl seats were on the Superdome terrace, which is the stadium's upper level, in the 20th row. Those tickets cost $3,000 each on Ticketmaster , although some seats nearby were ...
The superior cerebral veins drain into the superior sagittal sinus individually. The anterior veins run at near right angles to the sinus while the posterior and larger veins are directed at oblique angles, opening into the sinus in a direction opposed to the current (anterior to posterior) of the blood contained within it.
These sightings came just a day after a drone collided with — and damaged — a "super scooper" fixed-wing aircraft, grounding the plane for several days of repairs and reducing the number of ...
The government agency is tightening its standards for "healthy" claims. And for the first time in 30 years, its labeling rules will be updated to reflect new nutrition standards.
The superior sagittal sinus divides into two parts called the transverse sinuses where the falx cerebri meets the tentorium cerebelli. [3] The sigmoid sinus, which continues the transverse sinus, empties into the jugular vein at the jugular foramen. The internal jugular vein leaves the skull and travels downward to the neck. [3]
