Textbook Question
Chapter 13, Problem 5TYC
When a patient needs a tendon graft, surgeons sometimes use the tendon of the Palmaris longus, a relatively dispensable muscle of the forearm. The median nerve lies nearby and looks very similar to this tendon. There have been cases in which a surgeon mistakenly removed a section of this nerve instead of the tendon. What effects do you think such a mistake would have on the patient?

femoral nerve
sciatic nerve
obturator nerve
anterior nerve
