Gastrointestinal motility occurs by the coordinated contractions of the tunica muscula ris, which forms the outer wall of the alimentary canal from the distal oesophagus to the external anal sphincter ...

The transverse tubules (t-tubules) are invaginations of the cell membrane rich in several ion channels and other proteins devoted to the critical task of excitation-contraction coupling in cardiac ...

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 ...

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 ...

BUFFALO, N.Y. -- In the 21st century, human tissue can be generated from stem cells and severed limbs are successfully reattached, while the physiological processes governing life's most fundamental ...

(CBS News) A chemical found in many antibacterial soaps, deodorants and mouthwashes has been shown in a new study to restrict muscle contractions in mice and fish, leading researchers to ponder what ...

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 ...
