Which muscle inserts on the calcaneus via the calcaneal tendon?

Explanation:
The heel insertion via the calcaneal tendon is a function of the calf muscles, specifically the gastrocnemius. The calcaneal tendon (Achilles) is formed by the convergence of the gastrocnemius and soleus (with plantaris also contributing), and it attaches to the calcaneus. Gastrocnemius originates above the knee and crosses both the knee and ankle, allowing strong plantarflexion as it pulls on the calcaneus through this tendon. The other muscles listed are hamstrings that attach to the tibia or fibula and do not connect to the calcaneus via the calcaneal tendon, so they don’t insert there.
