The obturator nerve divides into anterior and posterior divisions while in the thigh. These two divisions are separated from each other by which muscle?

• A Adductor magnus
• B Adductor longus
• C Pectineus
• D Adductor brevis ✓

Explanation

Within the medial compartment, the anterior division of the obturator nerve descends in front of adductor brevis and the posterior division behind it, making adductor brevis the plane separating them. Both divisions then supply the adductor group. Adductor longus lies superficial to the anterior division, and adductor magnus is supplied mainly by the posterior division plus the tibial part of the sciatic nerve.
