QuestionChoice
The left common carotid artery is indicated by the arrow. The left common carotid artery arises directly from the aortic arch, whilst the right common carotid artery arises from the bifurcation of the aortic arch. Both common carotid arteries bifurcate at the level of the superior margin of the thyroid cartilage (C4) to form the external and internal carotid arteries, which supply the head, face and neck.

a
Provides arterial blood supply to the head, face and neck
QuestionChoice
The left common carotid artery is indicated by the arrow. The left common carotid artery arises directly from the aortic arch, whilst the right common carotid artery arises from the bifurcation of the aortic arch. Both common carotid arteries bifurcate at the level of the superior margin of the thyroid cartilage (C4) to form the external and internal carotid arteries, which supply the head, face and neck. Venous drainage of the neck is provided by the internal and external jugular veins and the vertebral veins. The external jugular vein terminates by draining into the subclavian vein. The internal jugular vein then unites with the subclavian vein to form the brachiocephalic vein. The brachiocephalic vein eventually becomes the superior vena cava, which drains into the right atrium.
