Please double check my work, are these correct? True or False? The tunica media is supplied by nerves of the autonomic nervous system. Answer: True – The tunica media is supplied by the autonomic nervous system (mainly the sympathetic system) to regulate vasoconstriction and vasodilation. True or False? Arteries have a much thicker tunica media when compared to veins. Answer: True – Arteries have a thicker tunica media than veins to withstand higher blood pressure and actively regulate blood flow. True or False? The tunica externa is the innermost tunic of a blood vessel. Answer: False – The tunica interna (intima) is the innermost layer, while the tunica externa (adventitia) is the outermost layer. True or False? The mandibular artery is located in the head and neck region. Answer: True – The mandibular artery is a branch of the external carotid artery, supplying blood to structures in the head and neck. True or False? The ophthalmic artery can be found in the eye. Answer: True – The ophthalmic artery is a branch of the internal carotid artery, supplying blood to the eye and surrounding structures. True or False? There are a total of two femoral arteries in the human body located in the brachial region of the body. Answer: False – There are two femoral arteries, but they are located in the thigh (femoral region), not the brachial (arm) region.
