Which muscle is located in the leg and helps with standing on tiptoe?

Explanation:
Stand-on-toes ability comes from plantarflexion at the ankle, the action of lowering the front of the foot and lifting the heel off the ground. The main muscle driving this movement is the gastrocnemius, a major calf muscle that joins the Achilles tendon and inserts into the heel bone. When it contracts, it pulls the heel upward and the person rises onto the toes. This is why standing on tiptoes relies on the gastrocnemius. The other muscles listed aren’t involved in this ankle movement: the rectus abdominis is for abdominal flexion, the deltoid moves the shoulder, and the quadriceps femoris extends the knee.
