Upper Limb Anatomy and Function

The video tutorial provides an in-depth look at the bones of the forearm, specifically the radius and alna. It begins with an introduction to these bones, followed by a detailed examination of the radius, highlighting its features such as the head, neck, and radial tuberosity. The tutorial then shifts focus to the alna, discussing its features like the O cranin and coroni process. Finally, the video covers the joints and articulations involving these bones, explaining how they interact with each other and other bones in the arm.
