- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

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 ...

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.

Large-conductance calcium-activated potassium (BK) channels are critical determinants of smooth muscle function by mediating rapid feedback between intracellular calcium levels and membrane potential.

People often discuss the importance of removing, or “flushing out,” lactic acid from the blood after intense exercise to reduce muscle soreness, speed recovery, or boost athletic performance. After ...

The findings could have implications for robotics, prosthetics and energy efficient machines. John McGrath and José Alvarado with HillBot, a robot designed to test parameters of muscle strength and ...

Most machines don't improve with use. Old pickup trucks don't gradually become Ferraris just by driving them fast, and a pocket calculator won't change into a supercomputer by crunching lots of ...

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, ...

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 ...
