Which artery completes the deep plantar arterial arch in the sole of the foot, running between the first and second layers of plantar muscles?
- A Lateral plantar artery
- B Deep plantar branch of the dorsalis pedis artery ✓
- C Arcuate artery
- D Medial plantar artery
Correct answer: B. Deep plantar branch of the dorsalis pedis artery
Explanation
The deep plantar arch is formed mainly by the lateral plantar artery, a branch of the posterior tibial artery, and is completed medially by the deep plantar branch of the dorsalis pedis, which enters the sole through the first intermetatarsal space. This connection links the anterior and posterior tibial systems. The arcuate artery lies on the dorsum of the foot and does not enter the sole.
