Verified step by step guidance

Identify the location and function of the calcaneal tendon, also known as the Achilles tendon, which connects the calf muscles to the heel bone (calcaneus).

Understand that the calcaneal tendon is a common tendon for the muscles of the posterior compartment of the leg, primarily the gastrocnemius and soleus muscles.

Review the anatomy of the gastrocnemius muscle, which is a major muscle of the calf and is responsible for plantar flexing the foot at the ankle joint and flexing the leg at the knee joint.

Recognize that the gastrocnemius muscle, along with the soleus muscle, forms the triceps surae, which inserts into the posterior surface of the calcaneus via the calcaneal tendon.

Conclude that the gastrocnemius muscle is the correct answer, as it inserts into the posterior calcaneus via the calcaneal tendon, unlike the tibialis anterior and peroneus longus, which have different insertion points.
