Dorsal Metatarsal Veins, Dorsal View

Description

Seen from the dorsum of the foot, the dorsal metatarsal veins course distally within the intermetatarsal spaces between adjacent metatarsals, superficial to the dorsal interossei and deep to the skin and superficial fascia. Each channel runs in parallel with its corresponding dorsal metatarsal artery, then converges proximally toward the dorsal venous arch over the metatarsus. Extensor tendons to the toes (extensor digitorum longus and extensor hallucis longus) cross the forefoot longitudinally, forming pale bands that sit anterior to the metatarsals and help orient the viewer to the second through fifth rays. For venipuncture and cannulation on the dorsum of the foot, appreciating the typical spacing of the dorsal metatarsal veins between the metatarsal shafts helps avoid transfixing an adjacent dorsal metatarsal artery or irritating a nearby cutaneous nerve branch. A frequent teaching point is the continuity of these veins with the dorsal venous arch and the great and small saphenous systems, which matters when tracing superficial thrombophlebitis or planning distal access when upper extremity sites are unavailable. Small vessels, tight skin, and mobile extensor tendons make placement unforgiving. Landmarks matter. Use this plate in gross anatomy labs when teaching forefoot topography, in nursing and paramedic skills curricula for peripheral IV access, or in podiatry and vascular surgery materials that discuss distal venous drainage and dorsal foot incisions along intermetatarsal intervals. It also suits medical publishing layouts that need a clean dorsal correlation between metatarsal bones, extensor tendons, and the superficial venous network.
