At a minimum, select three named arteries and provide the following for each: - A locational description using proper regional AND directional terminology - The course of the artery, the tissues supplied by it, and any anatomical landmarks that are associated with your selected artery (e.g. – The left subclavian artery arises from the arch of the aorta, and passes laterally inferior to the clavicle before passing the first rib. It has multiple branches including the vertebral artery, the interior thoracic artery, the thyrocervical trunk, the costocervical trunk, and the dorsal scapular artery.

Branches of the subclavian artery supply the cerebellum and brainstem and muscles of the cervical and scapular regions.) Your structure exploration should be submitted as a separate document (in either PDF or Word form), containing properly cited references (in APA format).

Left Gastric Artery

It is the smallest branch of the celiac trunk of the abdomen. At the cardioesophageal junction, it gives branches to the abdominal part of the esophagus. Some esophageal branches anastomose with the esophageal branches of the thoracic aorta. It continues to descend along the lesser curvature of the stomach and supplies both anterior and posterior surfaces of the stomach and anastomoses with the right gastric artery.

Popliteal artery

The popliteal artery is a direct continuation of the femoral artery which is situated in the anterior compartment of the thigh. It begins as the femoral artery passes posteriorly through the adductor hiatus in the adductor magnus muscle. The artery appears in the popliteal fossa on the upper medial side under the margin of the semimembranosus muscle. It descends through the fossa along with the tibial nerve and enters the posterior compartment of the where it divides into the anterior and posterior tibial arteries. The popliteal artery is the deepest of the neurovascular structures in the fossa and is difficult to palpate. The popliteal pulse can be examined by deep palpation medial to the midline of the popliteal fossa. Its branches include the anterior tibial artery, posterior tibial artery, sural arteries, and the various genicular arteries. It mainly supplies the knee joint and the various structures in the leg through the anterior and posterior tibial arteries.

Anterior tibial artery

The anterior tibial artery is a major blood vessel in the anterior compartment of the leg. It arises from the popliteal artery in the popliteal fossa, at the distal end of the popliteus muscle posterior to the tibia. It is accompanied by the anterior tibial vein along its course. The artery passes anterior to the muscle before passing through the tibia and fibula through an opening in the interosseous membrane. The artery then descends between the tibialis anterior and extensor digitorum longus muscles. The posterior tibial recurrent artery, anterior tibial recurrent artery, muscular branches, anterior medial malleolar artery, anterior lateral malleolar artery, and dorsalis pedis artery are the various branches that arise from the anterior tibial artery. It supplies blood to the various muscles in the anterior compartment of the leg and the dorsum of the foot.
