Membrane Potential
|
difference in electrical charge between the inside and the outside of a cell
|
|
|
Microelectrodes
|
Intracellular electrodes (piece of machine used to test charge)
|
|
|
Resting Membrane Potential
|
-70 mV
potential inside the resting neuron is about 70 mV less than the outside (polarized) |
|
|
Ions
|
particles that are either positively or negatively charged
|

|
How balance occurs?
Homogenous |
1. Random Motion- more likely to move down concentration gradient than up- move away from highly concentrated areas, and towards low concentrated areas
2. Electrostatic Pressure- accumulation tends to be dispersed by the repulsion among the like charges and attraction of opposite charges |
