Gastrocnemius and soleus
The Achilles tendon is attached to the calf muscle (gastrocnemius). It is also attached to the heel bone (calcaneus). Achilles tendon is also known as the calcaneal tendon (calcaneal hence the heel bone calcaneus).
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 attaches the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus).
superior extensor retinaculum and inferior extensor retinaculum
The gastrocnemius muscle is located in the posterior, or back part of the lower leg. The calcaneal tendon, more commonly known as the Achilles Tendon, is what connects the gastrocnemius muscle to the calcaneus bone.
The Achilles tendon is part of the muscular system. It connects the calf muscles to the heel bone (calcaneus) and is crucial for movements such as walking, running, and jumping.
Tendo calcaneus
The Achilles tendon structure joins the gastrocnemius to the calcaneus.
The soleus muscle inserts into the posterior calcaneus via the Achilles tendon.
The gastrocnemius, soleus and peroneus longus muscles insert at the heel (calcaneus) by way of the Achilles (calcaneal) tendon.
The connecting tendon between the calf and the thigh is the Achilles tendon. It is the largest tendon in the body and attaches the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus), allowing for movement such as pointing the foot and pushing off the ground while walking or running.
The Achilles tendon attaches the gastrocnemius muscle to the calcaneus.
