- 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) ...

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 ...

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.

Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

The previous three articles in this series explored the form and function of muscle and, in particular, skeletal muscle. This article outlines how the contraction of muscles (outlined in part three of ...

A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object. This is the most ...

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

The biology behind muscle pain: calcium chaos, microscopic damage, and the overlooked mechanism that explains how statins can ...
