Nerve anatomy

This issue has come up in Question 21.1 from the first paper of 2014. The candidates were invited to label a diagram of a dermatome-mapped homunculus. In order to supply the candidates with a readily available visual reference for this question, I have reproduced two free Wikipedia images in this revision article.

Radial nerve innervation and radial nerve distribution. What are causes & treatment of radial nerve palsy, radial nerve entrapment & radial nerve injury.
