== Structure ==

ItThe deep transverse metacarpal ligament is blendeda narrow fibrous band. It blends with the [[palmar metacarpophalangeal ligament]]s.

Its palmar surface is concave where the flexor tendons pass over it;. {{Clarify|reason=Unclear what this means in this context (posteriorly/dorsally?)|date=August behind2023|text=Behind}} it, the tendons of the [[interosseous muscles of the hand]] pass to their insertions.{{Citation needed|date=August 2023}}
