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.
Median artery
The median artery is an artery that is occasionally found in humans and other animals.
It is present in 8% of individuals. When present, it is found in the forearm, between the radial artery and ulnar artery. It runs with the median nerve and supplies the same structures as that nerve. It may be unilateral or bilateral.
