Muscle contraction is the generation of tension in muscle tissue, often resulting in a lengthening or shortening of the muscle. It involves the formation of rapidly cycling crossbridges between actin filaments and myosin motor proteins. Latest Research and Reviews ...

contraction. The type 1 ryanodine receptors (RyR1) is the major Ca2+release channel on the sarcoplasmic reticulum (SR) of myocytes in skeletal muscle and is required for excitation–contraction (E–C) coupling. This article explores the role of RyR1 in skeletal muscle physiology and ...
JAMES M. DOWNEY, GERD HEUSCH, in Heart Physiology and Pathophysiology (Fourth Edition), 2001 D. Contractility Two factors determine the force of contraction in cardiac muscle. The first, the length of the muscle, has already been discussed in detail. The second is termed contractility. As was...
Renal microvessels, due to their content of VSMC which constitute the media, may constrict or relax depending on the functional state of the VSMC. An understanding of the multiple processes influencing VSMC contraction and relaxation on a molecular level is therefore of paramount importance in app...
The following year, Eccles (1944) concluded from animal physiology experiments that disuse atrophy is best countered by exercise in which muscle shortens during contraction; he noted that strong isometric contractions can maintain muscle condition reasonably well. Eccles also determined that the effectivene...
Methods Thirty women and 27 men performed the non-fatiguing, repetitive, 1-h screwing task. For neuromuscular responses, the mean and difference values of static, median, and peak percentile muscle activity levels (normalized to a reference voluntary contraction force) and, for motor variability, ...
(ACTN2), which is crucial for muscle contraction was significantly downregulated in bedrest datasets, whileActn2showed both upregulation/downregulation in its expression depending on the spaceflight duration and skeletal muscle type (Fig.4b, d). Long-term duration of spaceflight resulted in severe ...
