Too many ions inside a neuron cell. What happens?

... effectively, and so it remains open, rapidly building up a concentration of sodium ions in the cell, and this disorder often affects potassium channels, so there is practically no way that the excess sodium ions can escape as they rush into the neuron. What happens when (too many) sodium ions ...

... shouldn't be in their genome. Sponges don't have a nervous system, yet they have many of the genes which required for building synapses (sodium channels). Again, this makes absolutely no sense in the Darwinian framework, but it makes perfect sense if the GOE is real. Dr Kenneth S. Kosik the ...

Re: Urea and membrane permeability of RBC

... on this topic on the web, so I think it is important. Red blood cells have a lot of urea transporters and a lot of aquaporins (water channels). That is how urea and water get into the red blood cell. It is not the urea itself going into the cell that is causing the cell to lyse. It ...

How can depolarization activate VGCC and TRPM5

Hi, I know that depolarization of a cell --> activates VGCC --> Ca2+ increases --> opens TRPM5 channels to let more Ca2+ in. But my questions are: 1. What is the mechanism behind the activation of VGCC? 2. How can TRPM5 channels open (how can they sense that they have ...
