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 ...

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 ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

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 ...

It is important to understand the principles of normal neuromuscular transmission when using neuromuscular blocking agents. The neuromuscular junction consists of the motor-nerve terminus, the ...

Researchers have just made the unexpected discovery of a novel organization of muscle fibers in Parophidion vassali, a fish that lives in the Mediterranean Sea and, like many fish, uses specialized ...

Muscles and nerve fibers allow a person to move their body and enable the internal organs to function. There are more than 600 muscles in the human body. People also have different types of muscle. A ...

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