Dissection of plantar aspect of left foot

Nerve supply to adductor hallucis muscle; plantar arterial arch, close-up view

The adductor hallucis has been detached and elevated to reveal the positions of the plantar arterial and venous arches, the deep plantar nerve and the more medially placed interosseous muscles.
