hi everyone. im getting a little confused about the cutaneous innervation of hand muscles. I guess it's been a long time or something. anyways can someone tell me the exact fingers (dorsal and palmar) each of the median ulnar and radial nervers innervate....and is there any discrepency between sources or it's just me being so confused ..:)

thanks

so is this correct?

The ulnar nerve innervates the medial 1.5 digits on the palmar surface of the hand, and 2.5 digits on the dorsal side. The radial nerve innervates the dorsal side of the lateral 2.5 digits, but does not innervate the tips of these fingers. The median nerve, which innervates the palmar side of the lateral 3.5 digits, also innervates the fingertips of these 3.5 fingers.
