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. [2] [3] They tend to be symmetrical, with the same pattern of large veins on each side of the skull. [1]
The outer layer of the skull has been removed and shows the diploic veins and inner layer. Most bones of the calvaria consist of internal and external tables or layers of compact bone, separated by diploë. The diploë is cancellous bone containing red bone marrow during life, through which run canals formed by diploic veins. The diploë in a ...
Diploë (/ ˈ d ɪ p l oʊ i / or DIP-lo-ee) is the spongy cancellous bone separating the inner and outer layers of the cortical bone of the skull. [1] It is a subclass of trabecular bone.
They connect the veins outside the cranium to the venous sinuses inside the cranium. They drain from the scalp, through the skull, into the larger meningeal veins [citation needed] and dural venous sinuses. They may also connect to diploic veins within the skull. [1] Emissary veins have an important role in selective cooling of the head.

"Aspirin can reduce heart attacks and strokes, and to some degree other clots like those in the deep veins of the legs," Blaha says. "In low doses, aspirin inhibits platelets and therefore reduces ...
Its inner surface presents the openings of the superior cerebral veins, which run, for the most part, obliquely forward, and open chiefly at the back part of the sinus, their orifices being concealed by fibrous folds; numerous fibrous bands (chordae Willisii) extend transversely across the inferior angle of the sinus; and, lastly, small ...
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]
