Radius (bone) in the grooves on the lower end of the bone. The lateral surface ("facies lateralis; external surface") is convex throughout its entire extent and is known as the convexity of the radius, curving outwards to be convex at the side. Its upper third gives insertion to the supinator muscle. About its center is a rough ridge, for the insertion of the pronator teres muscle. Its lower part is narrow, and covered by the tendons of the abductor pollicis longus muscle and extensor pollicis brevis muscle. The upper extremity of the radius (or proximal extremity) presents a head, neck, and tuberosity.
A Bone for a Bone when Geo P. Dog digs a hole and dumps a bone on the Gophers and then dirt as he fills the hole in. Geo does remove the bone upon Tosh's request, but realizing that it was gophers who asked him to move the bone, he returns to the same hole to rebury the bone. This time, Mac goes up, only to be grabbed by Geo. Mac then yells for help, which arrives in the form of Tosh and a hammer, which Tosh uses to knock Geo's head into his collar, allowing the Gophers to return to their hole and escape
