cardiac muscleAppropriate regulation of the contraction of cardiac myocytes within the heart is critical for its physiological function, allowing the heart to alter its power output in line with circulatory demand. Normal myocyte contraction requires a rise in intracellular calcium to activate the ...

-At rest, cardiomyocyte sarcomeres are not at optimal length for contraction -Increased preload/EDVlengthensout the sarcomeres in cardiomyocytes, leading to more forceful contractions -Not dueto innervation or hormones, Intrinsic property of cardiac muscle cells due to their length-tension properties ...
Other articles where muscle contraction is discussed: muscle: Whole muscle: Striated muscle contracts to move limbs and maintain posture. Both ends of most striated muscles articulate the skeleton and thus are often called skeletal muscles. They are atta
When a muscle fiber contracts, it also shortens so that external work can be performed. If we were to isolate a piece of cardiac muscle and study the effects of afterload on the velocity of fiber shortening, we would find that the greater the afterload, the slower the velocity of ...
