This article was originally posted on Quora as an answer to the question: "How do I remember all the brachial plexus? Any mnemonics?" Written by: Amith ES, Medical Student. Traveler. Foodie. Let me share the mnemonic I studied in my first year Branches of posterior cord : ULTRA or ULNAR * Upper subscapular nerve * Lower subscapular nerve * Thoracodorsal nerve / Nerve to Latissimus Dorsi * Radial nerve * Axillary nerve PS : If you're studying the mnemonic ULNAR, don't get confused with Ulnar nerve Branches of lateral cord : LML * Lateral pectoral nerve * Musculocutaneous nerve * Lateral root of median nerve Branches of Medical Cord : M4U * Medial Pectoral nerve * Medial Cutaneous Nerve of Arm * Medial Cutaneous Nerve of Forearm * Medial root of Median Nerve * Ulnar Nerve A simplified diagram of Brachial Plexus (thanks to Anjeeth Anilkumar) : (AD = Anterior Division, PD = Posterior Division) Source
