The gastrocnemius, soleus and peroneus longus muscles insert at the heel (calcaneus) by way of the Achilles (calcaneal) tendon.
The plantaris, gastrocnemius and soleus muscles attach (via the Achilles tendon) to the superior aspect of the tuber calcanei.
Surgeons often use the Plantaris Tendon for tendon grafts needed in other parts of the body.
Achilles tendon is common to both the gastrocnemius and soleus muscles of the calf.
The Gastrocnemius and the Soleus flexes the knee and the foot. The Plantaris is an unimportant muscle. Many people do not have it and doctors tend to use this muscle for tendon graphs.
Tendon is an inelastic cord or band of tough white fibrous connective tissue that attaches a muscle to a bone or other part.
There are many muscles that attach to the calcaneus, but the two biggest ones are the gastrocnemius and soleus. These two muscles attach to the calcaneus, via the achilles tendon. The other muscles are: the foot intrinsic muscles, so they begin and end only in the foot, and the plantaris, which attaches to the femur, and travels down to the calcaneus.
The Achilles tendon is the largest tendon in the body and attaches the calf muscles. mainly the gastrocnemius and soleus to the calcanueus (heel).
The action of the calcaneal tendon is to allow your soleus and gastrocnemius muscles to (plantar) flex your foot.
Fibularis Longus and Fibularis Brevis are both Plantar Flexes, page 222 of the Human Anatomy & Physiology Lab Manual (Elaine N. Marieb and Susan J. Mitchell. The prime movers for plantar flexion are the gastrocnemius and soleus (known together as the triceps surae). The gastrocnemius is the larger of the two muscles and is the one visible if you "flex" the calf by lifting your heel off the ground and putting pressure on the front of the foot.
== == The plantaris has a short muscle belly, but the longest tendon in the body. Its belly lies at an oblique angle along the popliteal space of the posterior knee between the gastrocnemius heads; its tendon extends down the length of the leg and attaches to the calcaneus. It arises from the Lateral condyle of the femur and inserts at the calcaneus.
