"The impressive performance of the U.S. economy over the past couple of decades, despite shocks that in the past would have surely produced marked economic contraction, offers the clearest evidence of the benefits of increased market flexibility."

The increased ser 19-MRLC phosphorylation activates the myosin's ATPase producing crossbridge cycling and contraction.

In Greek, the root "rhe" translates to current or flow, and "basi" means bottom or foundation: thus the rheobase is the minimum current that will produce an action potential or muscle contraction.

There was a Med Service gadget, once-a tricky little device to produce contraction of chosen muscles.

It is used to produce contraction of the uterus.

The extension in the longitudinal direction produces contraction in the hoop direction as the fiber angle decreases until these dimensional changes are resisted by the body of the eel.

The reason the SA node controls the whole heart is that its action potentials are released most often to the heart's muscle cells; this will produce contraction.

Thermal fluctuations may produce infinitesimal expansion or contraction within the network, and the evolution of such fluctuations will ultimately determine the molecular morphology and the degree of hydration of the body.

Rock can be disintegrated by changes in temperature which produces differential expansion and contraction.

During the resting phase the tropomyosin covers the actin's active sites so that the actin-myosin interaction cannot take place and produce muscular contraction.
