Parietal foramen

From Wikipedia, the free encyclopedia

Bone: Parietal foramen
Left parietal bone. Outer surface. (Parietal foramen labeled at upper right.)
Latin	foramen parietale
Gray's	subject #32 134
Dorlands / Elsevier	f_12/12373499

At the back part of the parietal bone and close to the upper or sagittal border is the parietal foramen, which transmits a vein to the superior sagittal sinus, and sometimes a small branch of the occipital artery; it is not constantly present, and its size varies considerably.
