Which bones make up the shoulder, arm, and forearm?

The bones of the shoulder, arm, and forearm are responsible for a wide range of movements, from reaching and grasping to lifting and throwing. These bones work together to provide us with the flexibility and strength we need to perform everyday tasks.

The shoulder is made up of three bones: the clavicle, the scapula, and the humerus. The clavicle is a long, slender bone that connects the sternum (breastbone) to the shoulder blade. The scapula is a large, triangular bone that forms the back of the shoulder. The humerus is the long bone of the upper arm that connects the shoulder to the elbow.

The arm is made up of two bones: the radius and the ulna. The radius is the larger of the two bones and is located on the thumb side of the arm. The ulna is the smaller of the two bones and is located on the little finger side of the arm.

The forearm is made up of two bones: the radius and the ulna. The radius is the larger of the two bones and is located on the thumb side of the forearm. The ulna is the smaller of the two bones and is located on the little finger side of the forearm.
