Which two bones are found in the forearm?

The correct answer identifies the ulna and radius as the two bones located in the forearm. These bones play crucial roles in the anatomy and function of the upper limb. The radius is positioned on the lateral side of the forearm (thumb side), while the ulna is found on the medial side (pinky side). Together, they allow for a wide range of movements at the elbow and wrist. The ulna primarily articulates with the humerus at the elbow joint, while the radius allows for the rotation necessary for functions such as pronation and supination of the forearm.

The other choices do not accurately describe the bones found in the forearm. The tibia is a bone in the lower leg, while the phalanx refers to the bones in the fingers and toes. The femur is the thigh bone, and the humerus is in the upper arm, making them irrelevant in the context of the bones of the forearm. Understanding the correct anatomy helps in recognizing how these bones function together in daily movements and activities.
