## Wolff's law

[wôlfs]
Etymology: Julius Wolff, German anatomist, 1836-1902
the principle that changes in the form and function of a bone are followed by changes in its internal structure.

## law

principle or rule
• Davis' law soft tissues' tendency to shorten and contract unless subject to frequent stretching

• Hilton's law a joint and its motive muscles (+ insertions) are all supplied by the same nerve

• Hook's law tissue strain (i.e. change in length) is directly proportional to applied compressive or stretching stress, so long as tissue elasticity (recoil ability) is not exceeded

• inverse-square law radiation intensity is inversely proportional to square of distance from radiation source (rad = ?1/cm2)

• law of excitation muscle tissue contracts in direct proportion to stimulating current strength

• Newton's first law; law of inertia an object at rest will not move until acted upon by a force; an object in motion will remain in motion at constant velocity until acted on by a net force

• Newton's second law; law of acceleration acceleration is directly proportional to applied force and indirectly proportional to object mass (i.e. force = mass × acceleration)

• Newton's third law; law of reciprocal actions to every action there is an equal and opposite reaction; i.e. a body is maintained at rest by equal and opposing forces

• Pascal's law a fluid at rest transmits pressure equally in every direction

• Poiseuille's law vascular blood flow is inversely proportional to fourth power of vessel radius (i.e. the narrower the vessel, the greater the resistance to flow)

• Starling's law the greater the stretch imposed on a circular muscle (e.g. muscle layer of an artery), the greater its reciprocal recoil and contraction

• Wolff's law bone function changes cause bone structure modification (see bone modelling)

## Wolff's law,

n.pr a law according to which biologic systems such as hard and soft tissues become distorted in direct correlation to the amount of stress imposed upon them.

## Wolff's law,

n.pr See law, Wolff's.
Wolinella recta
n a microorganism associated with progressive periodontal destruction and refractory forms of periodontitis. A regimen combining antibiotic treatment, débridement, and home oral care seems to suppress or control periodontal infections. Also called
C. rectus.

## Wolff's law

the law that skeletal transformation is dependent on the exertion of pressures from outside the animal.
