Question

Using the letters from column B, match the artery descriptions in column A. (Note that some require more than a single choice.)
Column A
  (1) unpaired branch of abdominal aorta
  (2) second branch of aortic arch
3) branch of internal carotid
(4) branch of external carotid
  (5) origin of femoral arteries
Column B
a. right common carotid
b. superior mesenteric
c. left common carotid
d. external iliac
e. inferior mesenteric
f. superficial temporal
g. celiac trunk
h. facial
i. ophthalmic
j. internal iliac

Accepted Answer

Step 1: Identify the unpaired branches of the abdominal aorta. Recall that the abdominal aorta gives off three major unpaired branches: the celiac trunk, the superior mesenteric artery, and the inferior mesenteric artery. From the options, these correspond to letters g (celiac trunk), b (superior mesenteric), and e (inferior mesenteric). Step 2: Determine the second branch of the aortic arch. The aortic arch typically gives off three branches in order: the brachiocephalic trunk (which divides into the right common carotid and right subclavian), the left common carotid artery, and the left subclavian artery. Therefore, the second branch is the left common carotid artery, which corresponds to letter c. Step 3: Identify a branch of the internal carotid artery. The internal carotid artery gives off several branches, one of which is the ophthalmic artery. From the list, the ophthalmic artery corresponds to letter i. Step 4: Identify a branch of the external carotid artery. The external carotid artery has several branches including the facial artery (h) and the superficial temporal artery (f). Both are branches of the external carotid, so both letters h and f apply here. Step 5: Determine the origin of the femoral arteries. The femoral arteries are continuations of the external iliac arteries after they pass under the inguinal ligament. Therefore, the origin corresponds to the external iliac artery, letter d.
