Communications with the emissary veins (parietal, mastoid and occipital) have also been observed.doi:10.1007/978-3-642-68242-1_2Johannes LangSpringer Berlin Heidelberg
Although the associated vascular elements are called “emissary veins,” the vessels have no valves and the blood flow can occur in both directions. These passages are particularly active in draining the endocranial cavity in situations of heat stress. Otherwise, the blood flow is reduced or ...

The course of the frontal diploic vein in the mole Talpa and the tree shrew Tupaia is described and compared to the frontal diploic vein of other mammals. The frontal diploic vein in Talpa and Tupaia connects the dorsal sagittal sinus to the veins of the orbit and has an emissary ...
The frontal diploic vein in Talpa and Tupaia connects the dorsal sagittal sinus to the veins of the orbit and has an emissary function. In certain other mammals it has a diploic function and may drain towards the orbit (e.g., Orycteropus ) or towards the dorsal sagittal sinus (e.g.,...
