[Tendon fibril rotation under the influence of hydration and temperature changes]
Abstract:
Hydration of an isolated rat tail tendon fibril induces its rotation. A similar effect is observed under the influence of temperature changes in the range of 12-38 degrees C. The direction and intensity of the rotation do not depend on the length of a tendon fibril in the range of 12-80 mm. A probabilistic character of the distribution of right- and left-rotating collagen molecules in the tendon was revealed. The direction and intensity of fibril rotation depends on the predominance of the amount of right- and left-rotating collagen molecules. The role of the rotation of collagen bundles in the mechanism of excitation of mechanoreceptors by the action of temperature is discussed.
