Dissection of dorsolateral aspect of left foot and ankle
Dorsal metatarsal arteries; dorsal interosseous muscles, viewed from above
The dorsal interossei have been separated slightly from their bony origins to expose the metatarsal arteries. In this foot these vessels spring largely from the perforating arteries rather than from the arcuate artery (12) which is extremely small.
