Boundaries & Contents of the Cubital Fossa

The video tutorial provides an in-depth exploration of the cubital fossa, a triangular area on the anterior surface of the elbow. It covers the boundaries formed by muscles and bones, and details the contents within the cubital fossa, including both superficial and deep layers. Key structures such as the brachial artery, median nerve, and various veins are discussed, along with their anatomical significance. The tutorial also touches on the genetic variations in the superficial veins and the role of the bicipital aponeurosis in stabilizing elbow flexion.
