Cross sections of the upper extremity: Forearm level

This video tutorial explores the cross sections of the forearm, focusing on the orientation, bones, muscles, and neurovascular structures. It begins with an introduction to the forearm's pronated position and the anatomical directions. The tutorial then covers the bones, including the radius and ulna, and their joints. The muscles are divided into anterior and posterior compartments, with detailed descriptions of each muscle's location and function. Finally, the video examines the major blood vessels and nerves, explaining their paths and connections.
