  • Scar-

Muscles Power:

Accessory Nerve:

• • Hypoglossal nerve-

  • Long thoracic nerve-

  • Axillary nerve-

  • Radial nerve-

  • Median nerve-

  • Ulnar nerve-

  • Sciatic nerve-

Causes of Peripheral nerve lesion:

• • Causes of single nerve involvement-

    • TRAUMATIC- It may be due to (a) Closed injury which usually causes either neuropraxia or axonotmesis lesion of the nerve or (b) Open injury which usually causes neurotmesis

    • INFLAMMATORY- Herpes Zoster, Leprosy, Diphtheria

    • NEOPLASTIC- Neurofibroma, Neurofibrosarcoma

    • MISCELLANEOUS- Tunnel syndrome, Lead poisoning, Arsenical poisoning, Diabetes etc.

  • Causes of multiple nerves involvement-

    • INFLAMMATORY- Herpes Zoster, Leprosy, Diphtheria
