26.06.2012: Review article - Since Ringer’s discovery of the importance of Ca2+ for muscle contraction, heart physiology has explained an increasing number of physiological phenomena by moving the ...

Calcium-uptake and ATPase studies carried out on fragmented sarcoplasmic reticulum from muscle of patients with Duchenne dystrophy showed low initial and total calcium uptake, low ATPase activity a ...

Muscle mass begins to naturally decline as we age, but fitness experts say there are key strategies that can help women maintain and build new muscle after 50.

A new method for assessing sarcoplasmic reticulum (SR) Ca2+-leak in atrial myocytes using confocal line-scan Ca2+ imaging is proposed. This approach offers a simpler and more ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a University of Michigan study.

Learn more about the different types of muscle contractions, how to do them, what they’re used for, and the benefits.

The sarcoplasmic reticulum of cardiac muscle is found to be much less extensive and less precisely arranged in relation to the cross-banded pattern of the myofibrils, than it is in skeletal muscle. It ...

This requires nerves in the brain to activate cells within muscle to release calcium ions from their internal store, the sarcoplasmic reticulum. Electrical signals sent from the brain are transmitted ...

The myofibrils occupy a large cell volume and are surrounded by cisternae of the smooth endoplasmic reticulum (or sarcoplasmic reticulum), which stores the calcium essential for muscle contraction.
