Which bone lies between the wrist and fingers in the hand?

• A. Carpals
• B. Metacarpals
• C. Phalanges
• D. Radius

Answer: (B)

The metacarpal bones form the palm, lying between the wrist (carpal bones) and the fingers (phalanges). There are five of them, one for each finger, extending from the carpal bones at the wrist to the bases of the proximal phalanges in the fingers. The carpal bones are the small wrist bones, the phalanges are the finger bones, and the radius is a forearm bone that does not sit between the wrist and fingers. This makes the metacarpals the structures that literally bridge the wrist and the fingers.
