no you should not strike the joint ,but as the name suggest we should strike the tendon

Does a Deep tendon reflexes are tested with a reflex hammer used to strike a joint?
yes
How do you use a reflex hammer?
The reflex hammer is used to check a person's reflex reponses. It is intended for testing tendon reflexes by striking the tendons. The reflex hammer is held by the handle, particularly close to the end oposite the head, with the head resting on the tendon which you intend to test. Make sure that the head is correctly lined up relative to the tendon. The hammer should be held against the tendon for some time such that the person being tested does not know when to expect the reflex. The hammer is now swung back and "bounced" off the tendon. It is important to make sure the hammer has a great velocity at the moment of impact (but don't use too much force to avoid hurting the tendon) and that it bounces off the tendon, rather than staying in contact with it. The action should be very brisk. It is usually completed in about a second.
Which of the following tests makes use of a special hammer?
The test that makes use of a special hammer is the neurological examination test known as the reflex hammer test. This test is used to assess deep tendon reflexes by tapping on specific areas on the body with the hammer.
What nerve is tested for patellar reflex?
The Femoral nerve. Wikipedia: Striking the patellar tendon with a tendon hammer just below the patella stretches the quadriceps muscles in the thigh. This stimulates stretch sensory receptors (i.e. muscle spindles) to trigger an afferent impulse in a sensory Ia-nerve fiber of the femoral nerve which synapses (without interneurones) at the level of L4 in the spinal cord, completely independent of higher centres.
What is tested in patella reflex?
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.
What nerve is tested for Achilles reflex?
1. Have the subject remove a shoe and sock and position the knee on the seat of a chair. 2. tap the Achilles tendon sharply with a reflex hammer. 3. observe the foot for any motion- the expected response should last between 100 and 300 msec so it may be difficult to visualize.
What is the Reflex that causes reciprocal activation of antagonist muscle?
- Golgi tendon reflex - When there is too much tension on a muscle, the afferent sensory nerves send the information to the spinal cord which sends its information to the cerebellum where the information is used to adjust muscle tension. Simultaneously, the motor neurons of the spinal cord that innervates the contracting muscle are inhibited and the antagonistic muscles are activated. I believe (but am not certain sure) the term you're looking for is "deep tendon reflex" (aka "monosynaptic reflex"). When a muscle's tendon is suddenly stretched, receptors within the tendon send signals to cause the muscle contract, so it opposes the stretch. This is the reflex that's tested when you tap just below your knee and your foot swings out (a knee-jerk reaction :-) See Glossary of Terms in Spinal Cord Injury Research [sci.rutgers.edu/dynarticles/CareCureGlossary_20Jun02.doc ]
The Moro reflex also known as the startle reflex is generally tested in whom?
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.
What is a archilles tendon?
Tendon is an inelastic cord or band of tough white fibrous connective tissue that attaches a muscle to a bone or other part.
What nerve is tested in a biceps reflex test?
musculocutaneous nervethe musculocutaneous nerve
What is Golgi tendon reflex?
The Golgi tendon organ is located where muscle fibers of skeletal muscle meet tendons. Made up of strands of collagen, the organ also contains nerve tissue. The major function of this organ is to sense muscle tension when a muscle is contracted, sending signals to the brain about how much force is being exerted and where. This important sensory organ was discovered by and named after Camillo Golgi, an Italian physician who made numerous discoveries about the function of the human nervous system in the late 19th and early 20th centuries. Classified as a proprioceptive sensory receptor, the Golgi tendon organ belongs to a family of structures that send information to the brain about how joints are functioning, including the angles at which they are held, the length of the muscle at any given time and how much tension is placed on the joint or the muscle. At one time, it was believed that the Golgi tendon organ responded only to high levels of muscle tension in order to protect muscles from overexertion. The theory that they respond only to high tension is incorrect, though. Studies done in 1967 proved that the Golgi organ responds to all levels of muscle tension, from slight to extreme. When a reflex hammer is tapped below the knee, the Golgi reflex at that joint is being tested.
Who has faster reflexes adults or teenagers?
We (not mentioning the exact names) have done a test on who has the faster reflexes and we have come up with an answer. We tested their reflex times by asking 10 students and 10 adults to turn on and off a specific timer as fast as they could. The slower the reflex time ( i.e.- 45) the slower the reflex. The faster the reflex time (19) the faster the reflex. When we tested the adults ( surprisingly) they had MUCH faster reflex times than the kids. Even though you'd think the opposite. The age categories were under 15 (kids) and over 15 (adults) so there's the proof.
