Achilles Tendon
This is what a tendon looks like
The Purpose of the Achilles tendon is to connect the heel to the gastrocnemius muscle. The Achilles tendon is the thickest and largest tendon in your body. The Achilles tendon holds your entire body weight when you walk, do push ups or run. You can pull your Achilles tendon and this doesn’t allow you to walk, run or jump. The tendon does stretch and if we didn’t have tendons the muscles would not work.
