Artery of Adamkiewicz
In human anatomy, the artery of Adamkiewicz (also arteria radicularis magna) is the largest anterior segmental medullary artery. It typically arises from a left posterior intercostal artery at the level of the 9th to 12th intercostal artery, which branches from the aorta, and supplies the lower two thirds of the spinal cord via the anterior spinal artery.
Cheek reconstruction
The external carotid artery (ECA), with contributions from the internal carotid artery (ICA) system, is the predominant arterial blood supply to the skin and muscles of the cheek. The greatest contribution is from the facial artery which traverses the face obliquely and terminates in the angular artery. The dorsal nasal artery runs along the nose and is the terminal branch of the ophthalmic artery, which is a terminal branch of the ICA. Many smaller branches and communications also exist.
