Block 1: Back and Upper Limb

MNEMONICS:

• Median Nerve vs. Ulnar Nerve: MEAT LOAF
  • Median Nerve innervates most Flexor Forearm muscles except: Flexor Carpi Ulnaris and Flexor Digitorum Profundus, which are both innervated by ulnar nerve.
  • Ulnar Nerve innervates most Hand muscles except: Lumbricals 1 &2, Opponens Pollicis, Abductor Pollicis Brevis, Flexor Pollicis Brevis (Superficial head), which are all innervated by Median Nerve.  “MEAT LOAF”

• Hand Nerve Pathologies: DR. CUMAB
  • DR = Radial Nerve damage –> Drop Wrist
  • CU = Ulnar Nerve damage –> Claw Hand
  • MAB = Median Nerve Damage –> Ape Hand, Benediction Hand

• Ulna vs. Radius Attachments: HURLS
  • HU = Humerus attaches to Ulna
  • RLS = Radius attaches to Lunate and Scaphoid

• Scaphoid in Greek means “boat” — scaphoid shaped like boat.
