A 17-year-old boy was stabbed during a gang fight, resulting in the transection of the obturator nerve. Which of the following muscles is completely paralyzed?
Correct Answer: Adductor longus
Description: The adductor longus is innervated by only the obturator nerve. Thus, injury here could completely paralyze the adductor longus. The pectineus is innervated by both the obturator and femoral nerves. The adductor magnus is innervated by both the obturator nerve and tibial pa of the sciatic nerve. The biceps femoris is innervated by the tibial poion (long head) and common peroneal poion (sho head) of the sciatic nerve.
