An anatomical illustration featuring the proximal ends of the radius and ulna bones, highlighting the critical interosseous membrane and the annular ligament (dashed circle) at the proximal radio-ulnar joint. It clearly demonstrates the ligamentous connections essential for forearm stability and movement, including a rotational axis.
