Question

Which artery is absent in frog?

• A. Renal artery
• B. Carotid artery
• C. Phrenic artery
• D. Right systemic arch

Answer 1

The correct option is C Phrenic artery

Phrenic artery is any of the several arteries supplying the diaphragm:

a : either of two arising from the thoracic aorta and distributed over the upper surface of the diaphragm—called also superior phrenic artery.

b : either of two that arise from the abdominal aorta either directly as separate arteries or from the celiac artery or a renal artery or from a common trunk originating in the abdominal aorta or the celiac artery and that supply the underside of the diaphragm and the adrenal glands—called also inferior phrenic artery.

In frog, innonimate and caudal arteries are absent. Also the intercostal arteries, phrenic arteries and lumbar arteries are absent.
