214 skulls were studied for the present study. A small foramen in the squamous part of the occipital bone just behind foramen magnum was noticed for the passage of emissary vein in one skull only, probably connecting occipital sinus with suboccipital venous plexus.
本研究共对214个颅骨进行了研究。仅在一个颅骨中发现枕骨鳞部靠近枕骨大孔处有一个小孔，有导静脉通过，该导静脉可能将枕窦与枕下静脉丛相连。
