The Boundaries of The Cubital Fossa

Leslie Samuel introduces the Essential Anatomy app and discusses the cubital fossa, a triangular depression in the forearm. He explains its boundaries, including the lateral and medial epicondyles, brachioradialis, and pronator teres muscles. The floor is formed by the brachialis muscle, while the roof consists of the bicipital aponeurosis, median cubital vein, and cutaneous nerves. The video concludes with a review of these anatomical features.
