Scapula

This tutorial explores the muscles of the anterior compartment of the forearm, focusing on their anatomy, function, and clinical relevance. It begins with an overview of the bones of the upper limb, followed by a detailed examination of the superficial and deep layer muscles, including their origins, insertions, functions, and innervations. The tutorial concludes with clinical notes on carpal tunnel syndrome, its symptoms, and treatment options.
