Researchers were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction. Although in the early stages, the research ...

Your skeletal muscles are made up of bunches of elongated, rod-shaped cells called muscle fibres. Each of your muscle cells is packed full of thinner fibres called myofibrils. These fibres contain ...

The contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

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

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

Beet juice boosts endurance for many (but not all) people, according to a series of studies over the past five years or so. The active ingredient appears to be nitrate, which somehow reduces the ...
