Describe the reflex action and its importance in the body’s defense mechanism.

  • The quick, unintentional reaction towards a stimulus that is harmful for the human body, is called a Reflex Action.
  • Reflex action is a reaction where the brain usually doesn’t get involved to analyze the stimulus, and the spinal cord, based on the experienced memory, creates the reflex.
  • This reaction usually appears towards those stimuli that may harm our body in any way, and thus it protects our body from getting injured.
