These vessels are channels that distribute blood to the body. Arteries of the trunk include the: thoracic aorta, celiac trunk, superior mesenteric artery, inferior mesenteric artery, and common iliac arteries (with its terminal branches internal iliac and external iliac arteries). They are the: olfactory (CN I), optic (CN II), oculomotor (CN III), trochlear (CN IV), trigeminal (CN V), abducens (CN VI), facial (CN VII), vestibulocochlear (CN VIII), glossopharyngeal (CN IX), vagus (CN X), accessory (CN XI), and hypoglossal nerves (CN XII).
