Cross sections of the upper extremity: Arm level

This video is the second installment in a series exploring the cross sections of the upper limb, focusing on the arm. It covers the skeletal framework, particularly the humerus, and details the muscles in both the anterior and posterior compartments. The video also examines the neurovasculature, highlighting major nerves and blood vessels. The tutorial aims to provide a comprehensive understanding of the arm's anatomy, preparing viewers for the next part of the series, which will focus on the forearm.
