Which ligament is located on the dorsal side of the wrist, between the ulna and the carpal bones?

• A. Transverse Carpal Ligament
• B. Dorsal Ulnocarpal Ligament
• C. Plantar Calcaneonavicular Ligament
• D. Pubofemoral Ligament

Answer: (B)

The question tests understanding of where ligaments connect the ulna to the carpal bones on the wrist’s dorsal (back) side. The dorsal ulnocarpal ligament runs from the ulna to the carpal bones (primarily the lunate and triquetrum) on the back of the wrist, forming part of the ulnocarpal complex that stabilizes the ulnar side of the wrist and helps resist separation when the hand is loaded. The other options are not between the ulna and carpal bones on the dorsal wrist: the transverse carpal ligament sits on the palmar side and forms the carpal tunnel; the plantar calcaneonavicular ligament is in the foot; the pubofemoral ligament is in the hip.
