Web17 sep. 2024 · Sodium ions ( Na+) are attracted to the inside of neurons at rest by two forces. The high concentration of (Na+) outside the cell pushes this ion into the cell down the concentration gradient. Likewise, the electrostatic pressure due to the negative charge within the neuron attracts the positively charged (Na+) inside. Since, however,… Web14 mei 2024 · The cytosol of animal cells contains a concentration of potassium ions (K +) as much as 20 times higher than that in the extracellular fluid. Conversely, the …
