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 ...

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 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 ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

Myotonic dystrophy type 1 (DM1) is the most common form of adult-onset muscular dystrophy, affecting about 1 in 8,000 people.
