hey guys, there's a picture in FA 2011 page 372 about dermatomes of hand.

According to this pic, sensory innervation on nail bed of thumb is innervated by radial n.

but I'v met more than one questions in kaplan Qbank about this and it said it is innervated by median n.

so I wanna make sure which one is correct?

can anybody help? thx a lot!


palmar aspect >>>> median nerve
dorsal aspect >>>> radial nerve

am I correct ????


its median nerve for the nails of thumb, index, midle and half of ring finger, and the rest by ulnar nerve
