Which two bones make up the forearm?

The forearm consists of two primary bones: the radius and the ulna. The radius is located on the lateral side of the forearm (the same side as the thumb), while the ulna is situated medially (near the body's midline). These bones work together to facilitate movement of the wrist and elbow, allowing for a wide range of motions, including pronation and supination.

Each bone has distinct anatomical features contributing to the forearm's overall function and structure. The connection between the radius and ulna is crucial for maintaining stability in the arm, especially during rotational movements. Understanding the roles of these two bones is essential for grasping concepts related to anatomy and movement in the human body.
