posterior compartment of the leg

Which muscle of the posterior compartment of the leg has two heads, one originating from the popliteal surface of the femur above the medial condyle and the other from the lateral surface of the lateral condyle of the femur?

• Gastrocnemius

• Soleus

• Tibialis Posterior

• Plantaris

What is the nerve supply for the Gastrocnemius muscle in the popliteal fossa?

• Common peroneal nerve

• Femoral nerve

• Sciatic nerve

• Tibial nerve

Which muscle of the posterior compartment of the leg is responsible for unlocking the knee by medial rotation of the leg?

• Flexor Hallucis Longus

• Tibialis Posterior

• Flexor Digitorum Longus

• Popliteus

Where does the Flexor digitorum Longus muscle originate from?

• Posterior surface of tibia below the soleal line and lateral to the vertical line

• Upper 1/3 of posterior surface of fibula & the head

• Popliteal surface of the femur above the lateral condyle

• Posterior surface of the tibia below the soleal line and medial to the vertical line

What is the action of the Soleus muscle in the ankle joint?

• Plantar flexion

• Dorsiflexion

• Eversion

• Inversion

Which nerve supplies the Flexor Hallucis Longus muscle?

• Sciatic nerve

• Posterior tibial nerve

• Common peroneal nerve

• Femoral nerve

What is the effect of an injury to the common peroneal nerve?

• Loss of dorsiflexion, loss of extension of toes & loss of eversion

• Weakness of planter flexion, loss of flexion of toes & weak inversion of foot

• Dorsiflexion, Eversion, Inversion

• Plantar flexion, Eversion, Inversion

What structures pass deep to the flexor retinaculum of the leg from medial to lateral?

• Flexor Digitorum Longus, Flexor Hallucis Longus, Posterior Tibial Artery, Posterior Tibial Nerve

• Tibialis Posterior, Flexor Digitorum Longus, Posterior Tibial Artery, Flexor Hallucis Longus

• Tibialis Posterior, Flexor Digitorum Longus, Posterior Tibial Artery, Posterior Tibial Nerve

• Flexor Hallucis Longus, Tibialis Posterior, Posterior Tibial Artery, Flexor Digitorum Longus
