Just add salt...
When salt is poured on fresh frog legs, the muscles begin to twitch, giving them the appearance of still being alive. How is that possible?
When a creature dies, its neurons don't stop working right away. So long as there is still enough energy around to maintain that membrane potential, the neurons will work.
All cells are polarized, which means the concentrations of charged atoms, called ions, of the fluid inside them is different from the fluid outside them. It is this difference in ion concentrations that creates a difference in charge (or voltage) across membrane. This difference - called a membrane potential - allows neurons to work.
The reason this occurs is because the cells inside the legs are still intact. The sodium ion present in the salt acts as a signal from the brain, causing the muscle to contract and relax.

Stephen Miner very funny 😂
ReplyDeleteGrazie Corina, non sapevo queste cose. informazioni molto interessanti e scientifiche! Unico motivo per cui non condivido e dovuto all'immagine raccapricciante delle rane tagliate metà .
ReplyDeleteAs a professional chef , I have used this to advantage.....although some do not see the humour...
ReplyDeleteSo this is why the squid twitches in the dish when the japanese pour soy sauce over it. Chilling and horrific.
