The team found that calcium, which allows muscle contraction to take place, enters the body's cells in response to electrical signals. The calcium fills up a small structure in the cell and when this is full and starts to empty, it forces the muscle to relax by preventing any more calcium entering the cell, even when it receives contraction signals.
Professor Wray explains: "Electrical signals in nerves and muscles are important for all activity, from thinking to drinking. It is important for the body to be active, but it is also important for it to relax, so that it doesn't over work itself. For example, in childbirth the uterus contracts and relaxes at regular intervals to allow a baby to pass through the birth canal.
"But when we get cramps for example, our muscle is contracting too hard or too often and in the case of the ureter it would cause kidney damage. It is therefore crucial that our muscles have periods of relaxation and we have now uncovered how this occurs. This understanding should allow doctors to work more accurately with the body's natural mechanisms when treating patients."

"Big Tech and mainstream media are constantly trying to silence the independent voices that dare to bring you the truth about toxic food ingredients, dangerous medications and the failed, fraudulent science of the profit-driven medical establishment.
Email is one of the best ways to make sure you stay informed, without the censorship of the tech giants (Google, Apple, Facebook, Twitter, YouTube, etc.). Stay informed and you'll even likely learn information that may help save your own life."
