The responsiveness of the stretch receptors in the patellar ligament.

∙ 14y ago
The patella reflex tests the integrity of the patellar tendon and the sensory and motor pathways that control the reflex. When the patellar tendon is tapped, it should cause the quadriceps muscle to contract and the lower leg to extend. If there is a lack of response or an abnormal response, it can indicate a problem with the nervous system.

Does a Deep tendon reflexes are tested with a reflex hammer used to strike a joint?
yes
Which ligament of the initiates the knee jerk reflex when tapped?
The patellar ligament initiates the knee jerk reflex when tapped. When the patellar tendon is tapped just below the patella, the sensory neurons detect the sudden stretch and send an impulse to the spinal cord. This reflex causes the contraction of the quadriceps muscles, resulting in the extension of the leg.
What is the effector involved the patellar reflex?
In order to provoke the patellar reflex one must strike the patellar tendon with a tendon hammer (and only a tendon hammer, striking with an ordinary hammer is ill-advised). In other words, strike the region immediately below the patella.

What happens to the patellar reflex if jendrassik's manoeuvre is performed at tha same time when patella is struck?
The Jendrassik maneuver is a medical maneuver wherein the patient flexes both sets of fingers into a hook-like form and interlocks those sets of fingers together. The tendon below the patient's knee is then hit with a reflex hammer to elicit the patellar reflex. The elicited response is compared with the reflex result of the same action when the maneuver is not in use. Often a larger reflex response will be observed when the patient is occupied with the maneuver, as the maneuver may prevent the patient from consciously inhibiting or influencing his or her response to the hammer.
How does the patella reflex differ from the pupillary reflex?
The two are different because of what triggers the reflex. While the patella is triggered through the sense of touch, the pupillary is triggered through light.
What is an example of a human reflex?
The most well-known human reflex is the knee-jerk (or patella) reflex. This is the one where you use a reflex hammer to hit the tendon just below the kneecap (or patella). The leg jerks out like you're kicking.
