Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...
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 ...

Genetic model reveals a form of calcium release is unnecessary for normal muscle contraction
The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...
The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ...
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, ...

Time under contraction is not directly measured in a typical weight training program. Most people really don't even think about the number of seconds a given muscle is forced to work. Indirectly, ...
Isometric exercises are exercises that involve the contraction of muscles without any movement in the surrounding joints. Most muscle strengthening exercises involve moving the joints, using the ...
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.
