・発見したギリシャの内科医 (physician) にちなんで「 ガレン大静脈 」とも呼ばれる。
「 船戸和弥のHP 」では「 大大脳静脈に注ぐ静脈 」として以下のように解説している。
「 大大脳静脈には、１対の脳底内大脳静脈、１対の内大脳静脈、１対の脳底内大脳静脈、１対の脳底静脈、１対の後頭静脈および１対の後脳梁静脈が注ぎ込む。」
以下は「 Wikipedia 」の解説文となる。
「 The great cerebral vein is one of the large blood vessels in the skull draining the cerebrum of the brain. It is also known as the "vein of Galen", named for its discoverer, the Greek physician Galen. However, it is not the only vein with this eponym. [clarification needed]
【 Structure 】
The great cerebral vein is considered as one of the deep cerebral veins. Other deep cerebral veins are the internal cerebral veins, formed by the union of the superior thalamostriate vein and the superior choroid vein at the interventricular foramina. The internal cerebral veins can be seen on the superior surfaces of the caudate nuclei and thalami just under the corpus callosum.[1] The veins at the anterior poles of the thalami merge posterior to the pineal gland to form the great cerebral vein.[1] Most of the blood in the deep cerebral veins collects into the great cerebral vein.[2] This comes from the inferior side of the posterior end of the corpus callosum and empties ie similarities, there are also differences between these two types of veins in the brain. The superficial veins at the dorsal parts of the hemispheres run upward and medially and empty into the large superior sagittal sinus in the upper margin of the falx cerebri. The superior sagittal sinus divides into two parts called the transverse sinuses where the falx cerebri meets the tentorium cerebelli.[3] The sigmoid sinus, which continues the transverse sinus, empties into the jugular vein at the jugular foramen. The internal jugular vein leaves the skull and travels downward to the neck.[3]
The veins of the brain have very thin walls and contain no valves. They emerge in the brain and lie in the subarachnoid space. They pierce the arachnoid mater and the meningeal layer in the dura and drain into the cranial venous sinuses.[3]」
