Deep plantar artery
The deep plantar artery descends into the sole of the foot, between the two heads of the 1st interosseous dorsalis, and unites with the termination of the lateral plantar artery, to complete the plantar arch.
It sends a branch along the medial side of the great toe and continues forward along the first interosseous space as the first plantar metatarsal artery, which bifurcates for the supply of the adjacent sides of the great and second toes.
