Question

What is the inside bone in the lower part of your arm?

Answer 1

The elbow is where the two bones of the forearm – the radius on the thumb side of the arm and the ulna on the pinky finger side – meet the bone of the upper arm -- the humerus. The lower end of the humerus flares out into two rounded protrusions called epicondyles, where muscles attach.
