"Ligamentous "
"Three palmar metacarpal arteries arise from the deep palmar arch. They anastomose with the common palmar digital branches of the superficial arch at the metacarpal heads. They also perforate the interosseous spaces to anastomose with the dorsal metacarpal arteries. The dorsal metacarpal arteries are branches of the posterior carpal arch 2."
