Carotid artery ^[1]

An artery found in the neck of vertebrates. There are external carotid artery (caro-tis externa, English externl carotid artery) and internal carotid artery (carotis interna, English internal carotid art-ery). The former is distributed to the top of the head and the face. The latter enters the brain and distributes into the brain and orbit. At the time of the occurrence, the gill mandibular arch was not formed in the gill arch, so it was not divided into the gill artery and the gill artery from the aorta. The external carotid artery is emitted from the front of the abdominal aorta. The internal carotid artery is formed by the blood vessels that extend to the third branchial arch. Sent to the aortic root. The aortic roots of other higher vertebrates disappear between the third and fourth aortic arches, so their third aortic arches form pure carotid arteries. The part of the abdominal aorta that runs between the third and fourth aortic arches is called the common co-rotid trunk; in higher vertebrates, the left and right common carotid arteries are divided by the common carotid arteries , And then branch into the external carotid artery and internal carotid artery.
