reaction

1. Reaction
   (Psycophysics) A regular or characteristic response to a stimulation of the nerves.
2. Reaction
   An action by a person or people in response to an event. The reaction may be primarily mental (“ a reaction of surprise”) but is usually manifested by some activity.
3. Reaction
   (Med) An action induced by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock.
4. Reaction
   Any action in resisting other action or force; counter tendency; movement in a contrary direction; reverse action.
5. Reaction
   (Politics) Backward tendency or movement after revolution, reform, or great progress in any direction. "The new king had, at the very moment at which his fame and fortune reached the highest point, predicted the coming reaction ."
6. Reaction
   (Mech) The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction. "Reaction is always equal and opposite to action, that is to say, the actions of two bodies upon each other are always equal and in opposite directions."

1. (n) reaction
   Any action in resistance or response to the influence of another action or power; reflexive action or operation; an opposed impulse or impression.
2. (n) reaction
   In dynamics, a force called into being along with another force, being equal and opposite to it. All forces exist in pairs; and it is a fundamental law (Newton's third law of motion) in mechanics that “action and reaction are always equal and contrary,” or that the mutual actions of two bodies are always equal and exerted in opposite directions. This law was announced, in the form that the quantity of motion is preserved in all percussion, simultaneously in 1669 by Christian Huygens, John Wallis, and Sir Christopher Wren, but was experimentally proved by Wallis only.
3. (n) reaction
   Action contrary to a previous influence, generally greater than the first effect; in politics, a tendency to revert from a more to a less advanced policy, or the contrary.
4. (n) reaction
   In chem., the mutual or reciprocal action of chemical agents upon each other.
5. (n) reaction
   total loss of irritability of the nerve below the lesion; on direct stimulation of the muscle
6. (n) reaction
   loss of irritability for very brief currents, such as induction-shocks;
7. (n) reaction
   retention and even increase of irritability for making and breaking of currents of longer duration (this galvanic irritability also becomes lost in the terminal stages of the severest forms);
8. (n) reaction
   increase of irritability for making currents at the anode as compared with the cathode, so that the anode closing contraction may exceed the cathode closing contraction;
9. (n) reaction
   a sluggishness of contraction and relaxation.
10. (n) reaction
    In pathology, the response of a nerve or muscle to an applied stimulus.
11. (n) reaction
    In serumtherapy, the occurrence of an interaction between two substances, as between an agglutinin and an agglutinable substance, or between toxin and antitoxin.
12. (n) reaction
    of measuring the rate of certain psychical and psychophysical processes.

1. (n) Reaction
   action resisting other action: mutual action: backward tendency from revolution, reform, or progress
