Which of the Following is True of the Radius

Question

Which of the following is true of the radius?
A) It is the medial bone of the forearm.
B) Its head articulates with the distal end of the ulna.
C) It articulates with the trochlear notch of the humerus.
D) none of these choices

Accepted Answer

The radius is not the medial bone of the forearm (that's the ulna), its head articulates with the radial notch of the ulna (not the distal end), and it does not articulate with the trochlear notch of the humerus (that's also the ulna).
