Researchers were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction. Although in the early stages, the research ...

- 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) ...

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 ...

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 ...

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 ...

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 ...

No one can live without a heart pumping blood to the rest of the body. New research from the University of Missouri School of Medicine reveals more information about this vital function and how it’s ...
