When a cell has resting potential, how is its composition?
Inside is more negative than the outside
Resting Potential relates to the
Gradients of ions across the cell membrane
What are cations important for neuron functions?
K+ and Na+ and Ca2+
K+ has a higher concentration
In the neuron
Na+ and Ca+ have higher concentrations
Outside of the neuron
What are anions important for neuron functions?
Organic anions and Cl-
Organic ions have a higher concentration
Inside the cell
Cl- is much higher
Outside of the cell
What are forces that drive neuron across the membrane?
- Chemical / Diffusion Forces that relate to the concentration gradients
