This is found in the [[bone]]s of the vault of the skull, and is the [[marrow]]-containing area of [[cancellous bone]] between the inner and outer layers of [[compact bone]]. The diploic veins drain this area to the outside of the skull. ==Specific diploic veins== They are usually four in number: one frontal, two parietal, and one occipital. * (1) the ''frontal'', which opens into the [[supraorbital vein]] and the [[superior sagittal sinus]]. * (2) 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]]. * (3) 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]]. * (4) 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). ==External links== * {{eMedicineDictionary|Diploic+veins}} {{VeinsHeadNeck}} [[Category:Veins]] {{circulatory-stub}}
