The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed.It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it.
The achilles tendon, tendo calcaneus attaches distally to the calcaneual tuberosity, and arises superiorly from the triceps surae complex of the gastrocnemius and soleus muscles. Achilles tendon at foetus. The Achilles tendon connects muscle to bone, like other tendons, and is located at the back of the lower
