Name the bones of the upper limb in order from proximal to distal.

• A. Radius and Ulna
• B. Humerus; radius and ulna; carpals; metacarpals; and phalanges.
• C. Femur; tibia; fibula; metatarsals
• D. Scapula; clavicle; humerus; radius

Answer: (B)

The main idea is the sequential arrangement of the bones from the shoulder toward the fingertips. From closest to the body outward, the bones are the humerus in the upper arm, followed by the two forearm bones radius and ulna, then the wrist bones called carpals, the palm bones called metacarpals, and finally the finger bones called phalanges. This order reflects how the limb is structured and moves: the arm bone connects to the forearm bones at the elbow, the forearm bones reach the wrist carpals, and those connect to the metacarpals and then the phalanges. The other options shift in ways that don’t follow this proximal-to-distal progression, or include bones not typically counted as part of the upper limb proper.
