The Deep Muscles Of The Anterior Compartment Of The Forearm

Leslie Samuel introduces the Muscle System Pro app and discusses the deep muscles of the forearm's anterior compartment. The video covers the innervation of these muscles, primarily by the anterior interosseous nerve, a branch of the median nerve, with an exception for the flexor digitorum profundus, which is partially innervated by the ulnar nerve. The video details the flexor digitorum profundus, flexor pollicis longus, and pronator quadratus muscles. Additional resources are available on the interactive-biology.com website.
