Anatomical terminology

The diploic veins are large, thin-walled valveless vessels that channel between inner and outer calvaria of the skull. They develop fully by two years after birth. The diploic veins drain this area into the dural venous sinuses. The four major types of diploic veins found on each side of the head are frontal, anterior temporal, posterior temporal, and occipital diploic veins.

Types of diploic veins[edit]

The frontal, which opens into the supraorbital vein and the superior sagittal sinus.

The anterior temporal, which is confined chiefly to the frontal bone, and opens into the sphenoparietal sinus and into one of the deep temporal veins, through an aperture in the great wing of the sphenoid.

The posterior temporal, which is situated in the parietal bone, and ends in the transverse sinus, through an aperture at the mastoid angle of the parietal bone or through the mastoid foramen.

The occipital, the largest of the four, which is confined to the occipital bone, and opens either externally into the occipital vein, or internally into the transverse sinus or into the confluence of the sinuses (torcular Herophili).
