    2. Threshold : minimum intensity, strong enough to initiate an action potential
    3. Sub maximal : higher strength than threshold
    4. Maximal : highest threshold strength
    5. Supra maximal : destructive to tissues
  • Classification of stimulus
    1. Mechanical : Pain, Pressure, and Touch
    2. Chemical : Acid, Alkali; Thermal: Warmth, Cold
