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.

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 ...

Scientists discover that muscles repair themselves by moving thousands of internal nuclei, a rapid process that is key after ...

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 ...

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 ...

Scientists at the University of Cincinnati and colleagues report that a regulatory protein found in skeletal muscle fiber may play an important role in the body’s fight or flight response when ...

Researchers at the University of Cincinnati say a regulatory protein found in skeletal muscle fiber may play an important role in the body's fight or flight response when encountering stressful ...

Cancer patients often lose excessive amounts of weight. This affects up to 80% of patients and is mainly due to a decrease in ...

Researchers have just made the unexpected discovery of a novel organization of muscle fibers in Parophidion vassali, a fish that lives in the Mediterranean Sea and, like many fish, uses specialized ...

Biological muscles act as flexible actuators, generating force naturally and with an impressive range of motion.
