  1. LAW OF FACILITATION
    "When an impulse has passed once through a certain set of neurons to the exclusion of others, it will tend to take the same course on a future occasion, and each time it traverses this path the resistance will be less"
  2. ARNDT'S LAW
    • Weak stimuli excite physiological activity
    • Moderately strong stimuli favor physiological activity
    • Strong stimuli retard physiological activity
    • Very strong stimuli STOP physiological activity
  3. DAVIS' LAW
    "If muscle ends are brought closer together, then the pull of tonus is increased, thereby shortening the muscle, which may even cause hypertrophy. If muscle ends are separated beyond normal, then tonus is lessened or lost, thereby "weakening" the muscle"
  4. HILTON'S LAW
    "A nerve trunk which supplies a joint, also supplies the muscles of the joint and the skin over the insertion of such muscles"
  5. LAW OF MOTION
    "To every action there is always an opposed equal reacction; or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts"
  6. RIGHTING REFLEXES
    "Reflexes, which through various receptors, in the labyrinth, eyes, muscles, or skin, tend to bring the body into its normal position in space and which resist any force acting to put it into a false position"
  7. WOLFF'S LAW
    (the law of Bone Transformation/Remodeling/Form Follows Function)
    "Every change in the form and the foundation of a bone, or in its function alone, is followed by certain definite changes in its internal architecture and secondary alterations in its external conformation"
  8. PFLUEGLER'S LAWS
    "Law of Unilaterality"
    "If mild irritation is applied to one or more sensory nerves, the movement will take place usually on one side only, the side that is irritated"
  9. PFLUEGLER'S LAWS
    "Law of Symmetry"
    "If the stimulation is sufficiently increased, motor reaction is manifested, not only by the irritated side, but also in similar muscles on the opposite side of the body"
  10. PFLUEGLER'S LAWS
    "Law of Intensity"
    "Reflex movements are usually more intense on the side of irritation; at times the movements of the opposite side equal them in intensity, but they are usually less pronounced"
  11. PFLUEGLER'S LAWS
    "Law of Radiation"
    "If the excitation continues to increase, it is propagated upward or downward, and reactions take place through centrifugal nerves coming from the cord segments higher up or down"
  12. PFLUEGLER'S LAWS
    "Law of Generalization"
    "When the irritation becomes very intense, it is propagated in the medulla oblongata, which becomes a focus from which stimuli radiate to all parts of the cord, causing a general contraction of all muscles of the body"
