Myosin II plays the most important role in cellular force generation. Myosin II molecules self-assemble into filaments with different structures depending on myosin II isoforms and other conditions ...

When stimulated by the autonomic nervous system to contract from the release of hormones or other chemical signals, smooth muscle cells shorten via the movement of actin and myosin myofilaments.

For every 1% increase in fatty muscle fraction, there was a 2% increase in the risk of CMD and a 7% increased risk of future serious heart disease, regardless of other known risk factors and body ...

There has never been a better time to get geeky about muscle growth — especially if you don't want to waste your gym time. In a new video, one of the researchers involved in many of these ...
