Anatomical terminology [edit on Wikidata]

Anatomy

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.^[2]

Tributaries

A sphenoparietal sinus receives small veins from the adjacent dura and sometimes the frontal ramus of the middle meningeal vein, communicating rami from the superficial middle cerebral vein, temporal lobe veins, and the anterior temporal diploic veins.^[2]
