IT is generally believed that the process which initiates contraction in striated muscle is the depolarization of the excitable membrane of the muscle fibre, although the mechanism by which membrane ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

Researchers describe a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fibre nuclei, and independently of muscle stem cells. Muscle is known to ...

A new study by researchers at Yale and Johns Hopkins University has discovered how asthmatic bronchial spasms — muscle contractions in the airway that cause difficulty breathing in asthma patients— ...

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 ...

Transverse tubules (T-tubules) play a significant role in muscle contraction. However, the underlying mechanism of their ...

Have you ever wondered about the biochemical mechanisms behind muscle contraction? If the answer is yes, then the (aptly named) Muscle Contraction app is for you! The app reads like an eBook, with ...

Segments of the obliquely striated body muscle of Ascaris were fixed at minimum body length after treatment with acetylcholine and at maximum body length after treatment with piperazine citrate and ...

Research has uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the ...

Skeletal muscle is the most abundant tissue of the human body (about 40%) and it plays essential role in locomotion and vital functions (heart rate, breathing). During aging, in a large majority of ...
