Dural sinuses are composed of dural mater lined with endothelium, making them distinct from arteries, veins, and capillaries. As part of the aorta, it is a direct continuation of the descending aorta of the thorax. This branching pattern occurs in 64. Key branches include the obturator artery, the inferior vesical artery in men and the equivalent vaginal artery in females, and the rectal and gluteal arteries.
The basilic vein follows a similar path but is located medially to the cephalic vein. My name is Grayson Wheatley.
Veins can be broadly classified based on their depth within the body. Most commonly, one arch is dominant [ 5 ].
Brachiocephalic trunk is absent in type VII, and right subclavian artery, right common carotid artery, left common carotid artery, and left subclavian artery leave the aortic arch separately. Most importantly, there are anatomic variations to the great vessel anatomy.
However, it is a misnomer because it does not in fact resemble the AA of the cattle which has only one branch that branches into right subclavian artery, a common truncus for common carotid arteries and left subclavian artery [ 7 ].

The large vein which returns blood from the lower extremities and the pelvic and abdominal organs to the right atrium of the heart. Yadav, and P. The abdominal aorta supplies blood to much of the abdominal cavity through numerous branches that become smaller in diameter as it descends. Veins of the Lower Limbs The deep veins of the lower extremity have valves for unidirectional flow and accompany the arteries and their branches. The major superficial veins of the upper limb are the cephalic, median cubital and basilic veins.
At the lower border, this vertebra becomes continuous with the descending aorta. Variations in the branching pattern of the AA are not rare.
Posteriorly, it is separated from the lumbar vertebrae by the anterior longitudinal ligament and left lumbar veins. D'Costa, and P.
Veins of the Head and Neck: The superficial veins of the upper extremity are shown in blue. Veins of the Head and Neck In the head and neck, blood circulates from the upper systemic loop, which originates at the aortic arch. Tsitouridis, M.
