The video tutorial explores the muscles of the posterior compartment of the forearm, focusing on their origins, insertions, functions, and innervations. It covers the extensor carpi ulnaris, extensor digiti minimi, extensor carpi radialis longus and brevis, extensor digitorum communis, brachioradialis, and anconeus. The tutorial highlights the role of these muscles in wrist and digit extension, as well as their contribution to elbow movements.
