@anatomy.of.motion: Did you know that our forearm bones are sometimes parallel and sometimes crossed? . Your forearm consists of two bones: the ulna and the radius. When you want to place your hand palm down, the radius actually rotates around the ulna. This movement is called pronation and is governed by the pronator teres and pronator quadratus muscles. Meanwhile, another muscle, the supinator, wraps around the radius, which later allows for the opposite movement, called supination. . Kapandji, A. „Biomechanics of Pronation and Supination of the Forearm”. Hand Clinics, t. 17, nr 1, feb 2001, s. 111–22, vii. . #forearm #ulna #radius #anatomy #biomechanics #anatomyofmotion

Anyone else gripping their forearm and rotating it to feel the bones and muscle move?

Why does it look like the Pronator Quadratus isn’t doing anything????

Any nursing school students present? We remember supination by thinking “holding a bowl of soup” so you have your hands out like your holding a bowl of soup 😂
