NERVES FROM THE POSTERIOR CORD 1. UPPER SUBSCAPULAR NERVE 2.LOWER SUBSCAPULAR NERVE 3.THORACODORSAL NERVE 4. RADIAL NERVE 5. AXILLARY NERVE

IMPORTANT NERVES AND AREA OF SUPPLY 1. MEDIAN NERVE( FORMED FROM BOTH MEDIAL AND LATERAL CORD)- A) SUPPLIES ALL THE FLEXORS OF THE FOREARM( EXCEPT FLEXOR CARPI ULNARIS AND MEDIAL HALF OF FDP) B) INTRINSIC MUSCLES IN THE LATERAL PALM INCLUDING THENAR EMINENCE) 2. ULNAR NERVE A) SUPPLIES THE MEDIAL HALF OF FDP AND THE FLEXOR CARPI ULNARIS B) SUPPLIES MOST OF THE INTRINSIC MUSCLES OF THE HAND INCLUDING THE HYPOTHENAR EMINENCE, AND SKIN ON THE MEDIAL SIDE OF THE HAND CLINICAL APPLICATION *INJURY TO MEDIAN NERVE-” APE HAND” INJURY TO ULNAR NERVE-” CLAW HAND”

INPORTANT NERVES AND THEIR AREA OF SUPPLY MUSCULOCUTANEOUS NERVE SUPPLIES THE BICEPS, CORACOBRACHIALIS AND BRACHIALIS AXILLARY NERVE SUPPLIES THE DELTOID AND TERES MINOR MUSCLE SUPPLIES THE SHOULDER JOINT RADIAL NERVE SUPPLIES THE TRICEPS SUPPLIES THE BRACHIORADIALIS SUPPLIES MOST OF THE EXTENSORS OF THE FOREARM * INJURY RESULTS IN “ WRIST DROP”

SWELLING OF THE TEDONS( OVERUSE) 2. PREGNANCY( EDEMA) 3. ARTHRITIS SYMPTOMS- TINGLING OR NUMBNESS-LATERAL PART OF HAND, WEAKNESS IN THUMB MOVEMENT TREATMENT- REST, SPLINTING,ANTI-INFLAMMATORY DRUGS, SURGERY
