What does the Achilles reflex do?

The Achilles reflex is a monosynaptic stretch reflex similar to the patellar reflex.

The Achilles reflex originates in the S1 and S2 nerve roots.

What is the purpose of the knee-jerk reflex?

The knee-jerk reflex, also known as the patellar reflex, is a simple reflex that causes the contraction of the quadriceps muscle when the patellar tendon is stretched. I describe the course of the reflex arc from muscle spindles in the quadriceps muscle to motor neurons that cause movement of the leg.
