 以下が「Wikipedia」の解説文となる。

「The lateral surface (facies lateralis; external surface) is convex throughout its entire extent. 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.」
