Pronunciation: re'fleks


  1. An involuntary reaction in response to a stimulus applied to the periphery, and transmitted to the nervous centers in the brain or spinal cord. Most deep reflexes are stretch or myotatic reflexes, elicited by striking a tendon or bone, causing stretching, even slight, of the muscle, which then contracts as a result of the stimulus applied to its proprioceptors.
  2. A reflection.

[L. reflexus, pp. of reflecto, to bend back]
