Achilles tendon is widely regarded as the strongest and largest tendon in the human body. It is exceptionally strong because it needs to withstand the significant forces generated during activities like walking, running and jumping.The primary function of the Achilles tendon is to transmit the force generated by the calf muscles to the heel, facilitating movement of the foot and ankle.

Achilles tendon

Extensor Retinaculum

The extensor retinaculum is a band of fibrous tissue that acts as a protective structure over the tendons on the dorsal surface of the foot and ankle. It helps to hold these tendons in place, preventing them from bowing out or moving too far away from the joint during movement.It is an important anatomical structure in the ankle that provides support and stability to the tendons of the anterior leg muscles, facilitating proper movement and function of the foot and ankle
