👉 The long bone in the forearm, on the side of the thumb.
Alright class, settle down and let’s take a look! Now, that dictionary definition – “the long bone in the forearm, on the side of the thumb” - is actually a bit of a trick! It's true that the radius is a long bone, but it's not where you might expect to find it. Let’s clear up this confusion with a little rhyme: “The radius lives near your wrist so free, It bends and twists for you and me! Below the ulna, it sits with grace, Helping hands in every place!” Essentially, the radius is a bone located in your forearm – specifically on the thumb side. It’s important for movement and rotation of your hand and wrist. Does that make more sense? Do you have any questions about where this bone likes to be?
