anatomy of Brachial plexus

  1. 1. DR HEENA AWAIS PHYSIOTHERAPIST
  2. 2. Parts of Brachial Plexus • R = ROOTS (ventral rami) • T = TRUNKS • D = DIVISIONS • C = CORDS • B = BRANCHES
  3. 3. Relationship of cords of brachial plexus with axillary artery
  4. 4. Branches of roots - Dorsal scapular nerve(C5) Long thoracic nerve (C5,C6,C7) muscular branches to longus colli & scaleni Branch to phrenic nerve Branches of upper- Nerve to subclavius (C5,C6) Trunk Suprascapular nerve (C5,C6) BRANCHES OF SUPRACLAVICULAR PART OF BRACHIAL PLEXUS
  5. 5. BRANCHES OF INFRACLAVICULAR PART OF BRACHIAL PLEXUS • Lateral cord Musculocutaneous nerve(C5,C6) Lateral pectoral nerve (C5,C6) Lateral root of median nerve (C5,C6) • Medial cord Medial cutaneous nerve of arm (C8,T1) Medial cutaneous nerve of forearm(C8,T1) Medial root of median nerve(C8,T1) Medial pectoral nerve (C8,T1) Ulnar nerve(C7,C8,T1) • Posterior cord Upper subscapular nerve(C5,C6) Lower subscapular nerve(C5,C6) Nerve to latissimus dorsi (C6,C7,C8) Axillary nerve(C5,C6) Radial nerve(C5,C6,C8,T1)
  6. 6.  Root value- C5  Supply – Rhomboid major & minor muscle Posterior view
  7. 7. LONG THORACIC NERVE Root value- C5,C6,C7 Supply – Serratus anterior muscle
  8. 8. BRANCHES OF UPPER TRUNK NERVE TO SUBCLAVIUS Root value – C5,C6 SUPRASCAPULAR NERVE Root value – C5,C6
  9. 9. Root value- C5,C6,C7 MEDIAL PECTORAL NERVE Root value- C8,T1
  10. 10. MUSCULOCUTANEOUS NERVE Root value – C5,C6,C7
  11. 11. 12-18 MEDIAN NERVE
  12. 12. MEDIAL CUTANEOUS NERVE OF ARM Root value- C8,T1 MEDIAL CUTANEOUS NERVE OF FOREARM Root value- C8,T1
  13. 13. Upper subscapular nerve Lower subscapular nerve Thoracodorsal nerve
  14. 14. Erb’s paralysis Klumpke’s paralysis Horner’s syndrome Injury to nerve of bell (nerve to serratus ant)
  15. 15. Injury of upper trunk
  16. 16. Birth injury Fall on shoulder During anesthesia
