Question 11

thumb and index finger weakness with intact sensation = lesion in ?

Answer 11

ant interosseious branch of median nerve

but if sensation lost = lesion in median nerve

Question 12

unable to extend MCP and thumb with intact sensation = lesion in ?

Answer 12

post inetrosseous branch of radial nerve

but loss of sensation then = radial nerve
