Step 3 - Dissection of the Posterior Thigh and Leg
Clean the and separate the muscles of the anterior compartment as seen in this
dissection.
These muscles include the tibialis anterior, extensor hallucis longus and extensor
digitorum longus muscles.
Separate the peroneus longus and peroneus brevis muscles in
the lateral compartment.
Complete your dissection by following the common
peroneal nerve where it winds around the head of the fibula and pierces the
peroneus longus m. The superficial peroneal branch exits from under the peroneus
longus about half-way down the leg, the deep peroneal branch passes down the anterior
compartment together with the anterior tibial artery before passing out onto
the dorsum of the foot. NOTE: The anterior tibial artery continues as the dorsalis pedis artery.
