Passive transverse mechanical properties as a function of temperature of rat skeletal muscle in vitro.

بررسی فعالیت حلقه های گاما دوک عضلانی و α-γ Linkage در دم موش (Rat)

Background and purpose : Muscle spindle is responsible for the control of skeletal muscle fibers function at rest and movement cycle, and is known as servo agent for voluntary movement. Function of this kinetic neceptor is completely dependent on the γ- ring activity would bring activity of la fiber and group ÏÏ spindle muscle afferent. Âlso, there is close functional of muscle relationship b...

Determination of the Passive Transverse Mechanical Properties of Skeletal Muscle under In Vivo Compression; Experimental and Numerical Aspects

Mechano-sensitivity of denervated Solus muscle of the rat L-type Ca channel mechano-sensitivity in long-term denervated Soleus muscle of the rat

Evidences showed that physical forces, as passive stretching or active contraction, may counteract various kinds of skeletal muscle atrophy due, for instance, to muscle immobilization, pathophysiology or denervation. In accord, active muscle contraction induced by functional electrical stimulation resulted helpful to reduce the muscle atrophic state in denervated man. Moreover, there are eviden...

Genetic Models in Applied Physiology Selected Contribution: Merosin deficiency leads to alterations in passive and active skeletal muscle mechanics

Jannapureddy, Suneal R., Nisha D. Patel, Willy Hwang, and Aladin M. Boriek. Selected Contribution: Merosin deficiency leads to alterations in passive and active skeletal muscle mechanics. J Appl Physiol 94: 2524–2533, 2003; 10.1152/japplphysiol.01078.2002.—The role of extracellular elements on the mechanical properties of skeletal muscles is unknown. Merosin is an essential extracellular matrix...

Passive stiffness of rat skeletal muscle undernourished during fetal development

OBJECTIVES The aim of the study was to investigate the effect of fetal undernutrition on the passive mechanical properties of skeletal muscle of weaned and young adult rats. INTRODUCTION A poor nutrition supply during fetal development affects physiological functions of the fetus. From a mechanical point of view, skeletal muscle can be also characterized by its resistance to passive stretch. ...
