What is the Achilles tendon?

The Achilles tendon is the largest, strongest tendon in the human body. Tendons are long, tough cords of tissue that connect muscle to bone. The Achilles tendon is located in the back of the heel and connects the heel bone to the calf muscle. It helps a person walk, run and jump. The Achilles tendon is able to endure stress, but sometimes injury can occur to the tendon when it is overly stressed.
