- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
C. CExplanation
The dorsalis pedis artery arises from the anterior tibial artery. This artery is responsible for supplying blood to the dorsal surface of the foot. It travels along the front of the leg and continues into the foot, where it forms the arcuate artery and gives rise to branches that supply the toes. The femoral artery is a major artery in the thigh, the obturator artery supplies blood to the medial compartment of the thigh, and the posterior tibial artery supplies blood to the posterior compartment of the leg. None of these arteries give rise to the dorsalis pedis artery.Rate this question:
