Fossa cubitalis (Ellenbeuge)

The video tutorial discusses the fossa cubiti, an indentation on the ventral surface of the elbow joint, located at the junction of the upper and lower arm. It explains the anatomical position, emphasizing the ventral view, and describes the triangular shape of the fossa cubiti with its three boundaries: lateral, medial, and cranial. The tutorial details the muscles forming these boundaries and the structures contained within the fossa cubiti, including the biceps tendon, brachial artery, and nerves. The radial nerve's unique path is also highlighted.
