What is "Achilles tendon"?

The Achilles tendon is a singular fibrous band that connects the calf muscles, specifically the gastrocnemius and soleus muscles, to the heel bone (calcaneus). It is the thickest and strongest tendon in the human body. The Achilles tendon plays a crucial role in the movement of the foot and lower leg, particularly during activities such as walking, running, and jumping. It enables the extension of the foot and assists in the propulsion of the body forward. Due to its location and function, the Achilles tendon is prone to injury, such as Achilles tendonitis or a rupture, which can significantly impact mobility and athletic performance.
