It is not a vital muscle for these movements.

Actions: It plantarflexes at the ankle joint, and because it crosses the knee, it is a flexor there.The tendon blends with the calcaneal tendon. The muscle descends medially, condensing into a tendon that runs down the leg, between the gastrocnemius and soleus. Attachments: Originates from the lateral supracondylar line of the femur.The plantaris is a small muscle with a long tendon, which can be mistaken for a nerve as it descends down the leg. The body of the gastrocnemius has been cut away to expose the underlying musculature. Actions: It plantarflexes at the ankle joint, and because it crosses the knee, it is a flexor there.įig 1 – The muscles in the superficial layer of the posterior leg.In the lower part of the leg, the muscle belly combines with the soleus to from the calcaneal tendon, with inserts onto the calcaneus (the heel bone). The fibres converge, and form a single muscle belly. Attachments: The lateral head originates from the lateral femoral condyle, and medial head from the medial femoral condyle.The gastrocnemius is the most superficial of all the muscles in the posterior leg. It has two heads – medial and lateral, which converge to form a single muscle belly.

Deep bursa of the calcaneal tendon – lies between the tendon and the calcaneus.
COMPARTMENTS OF LEG SKIN
Subcutaneous calcaneal bursa – lies between the skin and the calcaneal tendon.To minimise friction during movement, there are two bursae (fluid filled sacs) associated with the calcaneal tendon: The calcaneal reflex tests spinal roots S1-S2. The superficial muscles form the characteristic ‘calf’ shape of the posterior leg. They all insert into the calcaneus of the foot (the heel bone), via the calcaneal tendon.
