  • Stretch Reflex - an overview ScienceDirect Topics

    The stretch reflex consists of a monosynaptic response from the direct connection between Ia afferents and motor neurons, that may be followed by polysynaptic reflex activity. At rest, the stretch reflex can be obtained by a quick stretch, such as by tapping on a muscle tendon, which produces a burst of action potentials in the Ia spindle ...

  • Effects of teeth clenching on the soleus H reflex

    2017-4-1  Furthermore, Yamanaka et al. noted that the teeth clenching effect on muscle strength would depend on the muscle fiber composition. This discrepancy may be due to differences in the teeth clenching effect of different muscle types. Some studies have reported on the change that occurred at the motoneuron pool during muscle fatigue.

  • Re: How do you explain the phenomenon of reflex

    Make an effort not to tense your whole body when you clench your teeth. As another control, try it while clenching your fist instead. Make sure, also, that you hit the tendon with the same force every time. Let us know what you find, and if you still see this increase in the patellar stretch reflex, I will look into it further.

    2007-12-19  In the knee-jerk reflex (also known as th patellar tendon reflex) a tap is applied to the tendons of the quadriceps muscles, which stretches the muscles and their muscle spindles. A brisk tap excites the afferent fibers, because of their velocity sensitivity, ultimately causing the muscle to contract.

  • Natural Ways to Treat Teeth Clenching - Doctor Steve

    2020-6-20  Clenching is a continuous or periodic closing of the jaw under vertical pressure. Grinding is a rhythmic side-to-side movement or a forward-and-back movement. The teeth are under severe pressure when you clench and grind them. The constant moving of your teeth back and forth while grinding will loosen the teeth.

  • Exteroceptive reflexes in jaw-closing muscle EMG

    Exteroceptive jaw reflexes might play a role in normal functions of the mouth such as mastication. Until now these reflexes have only been studied under isometric conditions. The aim of this study was to compare exteroceptive reflexes in jaw muscle EMG during the closing phase of rhythmic open-close movements and clenching, at the same jaw gape and with similar muscle EMG. Reflexes consisting ...

Normal muscle stretch reflexes result in contraction only of the muscle whose ...

  • Reflex Tests Encyclopedia

    2020-7-15  Reflex Tests Definition. Reflex tests are simple physical tests of nervous system function.. Purpose. A reflex is a simple nerve circuit. A stimulus, such as a light tap with a rubber hammer, causes sensory neurons (nerve cells) to send signals to the spinal cord. There, the signals are conveyed both to the brain and to nerves that control muscles affected by the stimulus.

  • What is a Patellar Reflex? (with pictures)

    2020-6-24  This reflex is what is known as a monosynaptic reflex, because only one synapse needs to be crossed to complete the circuit that triggers it. When the area below the kneecap is hit with a reflex hammer , it hits the patellar tendon, which causes the quadriceps muscle in the thigh to contract, leading the leg to kick out.

    2016-8-1  The ankle jerk reflex is mediated by the S1 nerve root. The plantar reflex (Babinski) is tested by coarsely running a key or the end of the reflex hammer up the lateral aspect of the foot from heel to big toe. The normal reflex is toe flexion. If the toes extend and separate, this is an abnormal finding called a positive Babinski's sign.
