This stretch activates the pathway of nerves that supply the muscle and its tendons. • A two neuron reflex arc carries the signal by sensory neurons from the tendon and muscle, to nerves that supply that muscle at the spinal cord. The signal then returns to the muscle via motor neurons. This causes a motor response or jerk. • Let's go through some of the common reflexes carried out in Clinical practice. • The biceps tendon will elicit a flexion jerk, which assesses the integrity of C5-C6 Cervical spinal nerves. • The Patellar tendon insertion at the knee elicits a quadriceps twitch and knee jerk via the L3-L4 Lumbar spinal nerves. • Other tendon reflexes that could be examined are the Triceps, Supinator, Ankle or Achilles tendons and the Babinski reflex. • A normal response involves an equal, appropriate response on both sides of the body. However you could also get reduced or increased responses, known as Hyporeflexia and hyperreflexia. • You can trace the origin of the nerve back to the spinal cord using the Innervation path tool in Complete Anatomy. • Download Complete Anatomy on Mac: https://itunes.apple.com/us/app/compl... • Download Complete Anatomy on iOS: https://geo.itunes.apple.com/us/app/c... • Download Complete Anatomy on Windows: http://clkuk.tradedoubler.com/click?p...
