Final answer:
The radius articulates with both the ulna at the proximal radioulnar joint and the carpals at the distal radiocarpal joint. The correct answer is E) both B and D.
Step-by-step explanation:
The radius articulates with several bones, including the humerus and the carpals. Specifically, at the elbow joint, the head of the radius articulates with the capitulum of the humerus.
Additionally, the distal end of the radius articulates with the carpal bones to form the radiocarpal joint, which is part of the wrist. Therefore, the correct answer to which bones the radius articulates with is E) both B and D - the ulna and the carpals.
The radius bone located in the forearm articulates with both the ulna bone and the carpal bones. It forms a joint with the ulna bone at the elbow, which allows for the flexion and extension of the forearm.
It also forms a joint with the carpal bones at the wrist, allowing for movement of the hand. The correct answer is E) both B and D.
