The anterior tibial artery supplies which angiosome?

Explanation:
The key idea is angiosomes—the specific blocks of tissue fed by a named artery. The anterior tibial artery travels down the leg and crosses the ankle to become the dorsalis pedis, which supplies the dorsal aspect of the foot and the area around the anterior ankle. The other regions are supplied by different arteries: the heel and plantar surface mainly by the posterior tibial artery and its calcaneal/plantar branches, and the plantar arch by the posterior tibial’s plantar arteries with contributions from the lateral plantar. So the region fed by the anterior tibial artery’s angiosome is the anterior ankle.
