The intersegmental arteries are a set of 30 arteries arising from the embryonic dorsal aorta,[1] with each artery providing blood supply to one somite and its derivatives.
Cervical intersegmental arteries
[edit]The cervical intersegmental arteries merge into the vertebral artery[1] with the exception of the 7th (or possibly the 6th) cervical intersegmental artery, which becomes the subclavian artery.[2] The confusion arises because the vertebral artery drains into the subclavian artery following the disappearance of the dorsal aortae in part of the cervical region.
Thoracic intersegmental arteries
[edit]The thoracic intersegmental arteries all develop into the intercostal arteries.[1]
Lumbar intersegmental arteries
[edit]The lumbar intersegmental arteries develop into the lumbar arteries, with the exception of the 5th (last) lumbar intersegmental artery, which becomes the common iliac arteries.[1]
Sacral intersegmental arteries
[edit]These arteries merge into the lateral sacral artery.[1]
