A sphenoparietal sinus is situated under each lesser wing of the sphenoid bone near the posterior edge of this bone, [2] between the anterior cranial fossa and middle cranial fossa. [ citation needed ] It terminates by draining into the anterior part of the cavernous sinus .
The cavernous sinus receives blood from: [2] Superior and inferior ophthalmic veins [3]; Sphenoparietal sinus [3]; Superficial middle cerebral veins [3]; Inferior cerebral veins; Blood leaves the sinus via superior and inferior petrosal sinuses as well as via the emissary veins through the foramina of the skull (mostly through foramen ovale).
The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere.It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1]

The pterion is the region where the frontal, parietal, temporal, and sphenoid bones join. [1] It is located on the side of the skull, just behind the temple.It is also considered to be the weakest part of the skull, which makes it clinically significant, as if there is a fracture around the pterion it could be accompanied by an epidural hematoma.

A single layer of endothelium lines these veins supported by elastic tissue. They develop fully by the age of two years. The diploic veins drain this area into the dural venous sinuses. The four major trunks of the diploic veins found on each side of the head are frontal, anterior temporal, posterior temporal, and occipital diploic veins.
Ethmoid sinus cavities which are located between the eyes. Frontal sinus cavities which can be found above the eyes (more in the forehead region). Maxillary sinus cavities are located on either side of the nostrils (cheekbone areas). Sphenoid sinuses that are located behind the eyes and lie in the deeper recesses of the skull.
