The ovarian artery arises from the abdominal part of the aorta at the
level of the first lumbar vertebra. The artery is long and slender and
passes downward and laterally behind the peritoneum. It crosses the external iliac artery at the pelvic inlet and enters the suspensory
ligament of the ovary.
It then passes into the broad ligament and enters the ovary by way of the mesovarium.

A. i.e. Medial circumflex artery; B. i.e. Lateral circumflex artery; C.
i.e. Profunda femoris artery
Proximal femur (head & neck) is supplied by artery of ligamentum
teres (branch of obturator artery), medial (main) & lateral circumflex
femoral artery (both arise from profunda femoris artery, give rise to
ascending cervical (+ metaphyseal) and retinacular (+
epiphyseal:lateral & inferior) arteries and form extracapsular &
intracapsular subsynovial arterial rings

Inferior pancreaticoduodenal artery is a branch of superior mesenteric artery. It supplies the
pancreas and adjoining part of the duodenum. Its anterior and posterior branches
anastomose with the branches of superior pancreaticoduodenal artery. This anastomosis is
the only communication between the arteries of foregut and midgut.
Branches of superior mesenteric artery are:
Inferior pancreaticoduodenal artery
Jejunal and ileal branches
Ileocolic artery
Right colic artery
Middle colic artery
