- 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) ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 98, No. 12 (Jun. 5, 2001), pp. 6935-6940 (6 pages) To investigate the molecular basis of the voltage sensor that ...

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 ...

Skeletal muscle contraction is triggered by Ca2+ release from the sarcoplasmic reticulum (SR) in response to plasma membrane (PM) excitation. In vertebrates, this depends on activation of the RyR1 ...

The sarcoplasmic reticulum (SR) is a specialised organelle in skeletal muscle fibres that plays a pivotal role in regulating calcium dynamics crucial for muscle contraction and relaxation. Acting as ...

The ability to modify the intracellular concentrations of divalent calcium ions is vital to normal cell functioning. In the cells of the cardiac muscle, calcium ions play a crucial role in coupling ...
