A Hammer Strikes the Achilles Tendon to Elicit Which Stretch

Question

A hammer strikes the Achilles tendon to elicit which stretch reflex?
A) Babinski
B) Baroreceptor
C) Patellar tendon
D) Ankle jerk

Accepted Answer

The ankle jerk reflex, also known as the Achilles reflex, is elicited by tapping the Achilles tendon with a reflex hammer, which stretches the associated muscle spindles and results in a reflex contraction of the gastrocnemius and soleus muscles. The Babinski reflex is elicited by stroking the sole of the foot and observing the toe response, the baroreceptor reflex involves changes in blood pressure, and the patellar tendon reflex involves tapping the patellar tendon to elicit a contraction of the quadriceps muscle.
