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 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 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 ...

Calcium is the essential "on switch" for muscle contractions and a critical partner in maintaining hydration during hard ...

Some workouts leave you buzzing, muscles pumping, and energy on high. Others leave you wondering if you made any progress at all. The difference often comes down to more than just the weight on the ...
