The responsiveness of the stretch receptors in the patellar ligament.
Yes, deep tendon reflexes are tested with a reflex hammer, which is used to strike a tendon directly. This action stretches the muscle attached to the tendon, leading to a reflex contraction that is then assessed for strength and speed.
Typically, a reflex is tested a few times to ensure accuracy in the assessment. The number of tests can vary depending on the specific reflex being evaluated and the individual's response.
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.
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.
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.
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.
A reflex hammer is the triangular rubber-headed mallet with which your knee is struck during a physical exam.
The patellar reflex involves the tapping of the patellar tendon to elicit a knee jerk response, testing the integrity of the spinal nerves. The pupillary reflex involves the constriction of the pupils in response to bright light, mediated by the autonomic nervous system. Both reflexes are protective mechanisms but involve different anatomical pathways.

no you should not strike the joint ,but as the name suggest we should strike the tendon
The Moro reflex is typically tested in infants to assess their neurological development and response to stimuli. It is one of the primitive reflexes present in newborns and fades away by around 4-6 months of age.

the patella is the scientific name for the kneecap
patella We call this our "knee bone".
The knee bone is called the patella, commonly known as the kneecap. It is a small, flat, triangular-shaped bone that protects the front of the knee joint.
