Common carotid artery its right side below is the brachiocephalic trunk, and above, the trachea, the inferior thyroid veins, and the remains of the thymus; to its left side are the left vagus and phrenic nerves, left pleura, and lung. The left subclavian artery is posterior and slightly lateral to it. The cervical portions of the common carotids resemble each other so closely that one description will apply to both. Each vessel passes obliquely upward, from behind the sternoclavicular joint to the level of the upper border of the thyroid cartilage, where it divides. At the lower neck the two common carotid arteries
Striate arteries ventricular system. Lacunar infarcts may have serious functional consequences if they involve motor or sensory fibers in the internal capsule or may be "silent" if they involve other small regions of white matter or the basal ganglia. Striate arteries Striate arteries or ganglionic arteries arise from the middle cerebral artery and supply deep structures in the cerebrum, including the internal capsule and reticular formation. Strokes in these vessels are common and can cause extensive damage. This is because emboli are carried up the carotid and tend to be swept into the MCA, sometimes called the "artery of stroke", and are
