Dr. Ebraheim’s educational animated video describes muscle anatomy of the thigh.
•Medial thigh muscles
•Adductor longus muscle
•Adductor magnus muscle
•Adductor hiatus muscle
•Adductor brevis muscle
•Gracilis muscle
Obturator nerve
Also sensory innervation at the medial aspect of the thigh. The adductor magnus is innervated by the obturator nerve and by the tibial part of the sciatic nerve.
Function: Adduction of the thigh
Two extensors: sarotirus muscle, quadriceps muscle (includes four muscles: vastus laterlais, vastus intermedius, vastus medialis, rectus femoris)
Innervation: femoral nerve
Posterior thigh muscles : three flexors: hamstrings:
1Semimembranosus
2Semitendinosus
3Biceps femoris (long & short head)
Innervation: sciatic nerve : peroneal division short head of the biceps. Tibial division other hamstrings muscles. The peroneal nevre pasess deep to the biceps muscle. The hamstring function is knee flexion.
