The transverse metatarsal ligament is a narrow band which runs across and connects together the heads of all the metatarsal bones; it is blended anteriorly with the plantar (glenoid) ligaments of the metatarsophalangeal articulations.

Its plantar surface is concave where the Flexor tendons run below it; above it the tendons of the Interossei
