The Essential Bones of the Arm and Hand

  1. Humerus: The humerus, the longest and largest bone of the arm, spans from the shoulder to the elbow, providing structural integrity and facilitating arm movement.
  2. Ulna: The ulna is the larger and innermost bone of the forearm, positioned on the side of the little finger. It plays a pivotal role in the elbow’s hinging movement.
  3. Radius: The radius, positioned on the thumb’s side, is the smaller bone in the forearm, responsible for the forearm’s rotation around the ulna.
  4. Phalanges: The phalanges are the bones that make up the fingers and toes. Each finger houses three phalanges, while the thumb contains two.
  5. Metacarpus: The metacarpus comprises five metacarpal bones located within the palm, bridging the carpus and phalanges.
  6. Carpus: The carpus or wrist is a flexible joint composed of eight small, irregularly-shaped bones called carpals, which facilitate a range of wrist motions.
