Which bone in the wrist connects to the phalanges?

The metacarpals are the correct bones that connect to the phalanges. Each hand has five metacarpal bones, which form the middle part of the hand and play a crucial role in the structure and movement of fingers. The proximal ends of the metacarpals articulate with the wrist bones (carpals), while their distal ends connect to the phalanges, the bones of the fingers. This connection allows for the articulation and movement necessary for finger flexion and extension.

The other options, such as the scaphoid, capitate, and lunate, are all carpal bones located in the wrist and do not directly connect to the phalanges. Instead, they serve as articulating partners for the metacarpals and help form the wrist joint, facilitating wrist movements but not finger movements directly.
