Making the world better, one answer at a time. The receptor in the reflex arc of a stretch reflex are 'muscle spindles' which are spindle shaped receptors distributed throughout the belly of the muscle.
As you stretch the muscle, a message gets sent to your central nervous system (not necessarily your brain) that can cause a reflex contraction of the exact muscle that you are trying to stretch! The most common example of the stretch reflex is a test for the stretch reflex in your quadriceps (thigh muscles).In this test, the tendon below the knee (Patella tendon is hit with a small reflex hammer.he stretch reflex is something that is designed to protect us, but can get a little annoying when you are trying to get more flexible! Inside the millions of tiny fibers that make up each of your muscles are little cells called Muscle Spindles that measure how much stretch there is in your muscles.
