Action potentials, with no accompanying contraction, were recorded from muscle fibers in which the transverse tubular system had been disrupted. The results show that action potentials require an ...
Two related studies published today in Nature Metabolism show that a specialized intracellular recycling ...
The sarcoplasmic reticulum (SR) is a specialised organelle in skeletal muscle fibres that plays a pivotal role in regulating calcium dynamics crucial for muscle contraction and relaxation. Acting as ...
Muscles are made to move. Stretching and contraction stimulate biochemical pathways within muscle that maintain tissue health. When movement slows—when a broken limb is immobilized in a cast, for ...
