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 . The cremasteric reflex is elicited by stroking the inner aspect of the thigh, which causes the cremasteric muscle within the scrotum to contract and thereby elevate the testis and scrotum.

Fortunately, there is a very effective minor surgical treatment known as a microsurgical subinguinal cremaster muscle release, which releases this muscle to prevent this vigorous testicular retraction. The cremaster is also activated by a cold environment. If the cremaster reflex is strong enough, it can result in a retractile testicle, pulling the testicle out of the scrotum and up into the groin. Along with the dartos muscle of the scrotum, it regulates testicular temperature, thus aiding the process of spermatogenesis. 1,5 In the female, it involves the contraction of muscle fibers along the upper part of the Poupart or inguinal ligament and is sometimes called the inguinal reflex.

Although these upper motor neuron signs and symptoms may arise from damage anywhere along the descending pathways, the spasticity that follows damage to descending pathways in the spinal cord is less marked than the spasticity that follows damage to the cortex or internal capsule.For example, the extensor muscles in the legs of a patient with spinal cord damage cannot support the individual's . In patients with inflammation, such as that associated with orchitis, intratesticular blood flow is increased. You dont use proper technique, in which case the reflex will appear to be absent when it is present.
