The tendon reflex (deep tendon reflex, muscle stretch reflex, myotatic reflex) is a monosynaptic proprioceptive reflex.The afferent arc of the reflex starts from the stretch receptor in the muscle called the muscle spindle.The receptor is activated by sudden stretch, and an electric impulse generated there is conducted through Ia fibers to the anterior horn cells of the same segment, where the . [2], Clinically, a reflex arc termed the cremasteric reflex can be demonstrated by lightly stroking the skin of the inner thigh downwards from the hip towards the knee. It corresponds to the cremasteric reflex in males. Additionally, other studies confirm that it is also absent from significant numbers of males and more so at younger ages.
