emissary vein การใช้

Emissary veins have an important role in selective cooling of the head.
Also, rupturing the emissary veins will result in a subdural hematoma which will compress the brain.
In certain people, it can contain an emissary vein, referred to as the " petrosquamosal sinus ".
This foramen varies in size in different subjects, and is frequently impervious; when open, it transmits the emissary vein from the nose to the superior sagittal sinus.
The parietal emissary vein connects it with the superior sagittal sinus; and as it passes across the mastoid portion of the temporal bone, it receives the mastoid emissary vein which connects it with the transverse sinus.
