Dissection of anterior and medial aspects of thigh

Posterior branch of obturator nerve; innervation of adductor magnus by obturator nerve

The adductor brevis has been divided and removed to reveal the posterior branch of the obturator nerve passing into the adductor magnus. Branches of the sciatic nerve that enter the adductor magnus on its posterior aspect are visible in the dissection shown in view 184-4.

2. Pectineus muscle (cut off at origin)
3. Adductor brevis muscle (origin)
4. Adductor longus muscle (origin)
5. Obturator externus muscle
6. Posterior branch of obturator nerve
7. Adductor magnus muscle (upper pointer indicates adductor minimus)
8. Pectineus muscle (insertion)
9. Adductor brevis muscle (insertion)
10. Deep femoral artery
11. Femoral nerve
12. Iliacus muscle
13. Greater trochanter
