| 41. | He knew that living cells had a membrane potential; interior negative to the environment.
|
| 42. | Movement of calcium ions from the extracellular compartment to the intracellular compartment alters membrane potential.
|
| 43. | In some type of neurons, the membrane potential can synchronous activity of neighboring neurons.
|
| 44. | Depolarization is followed by the plateau phase, in which membrane potential declines relatively slowly.
|
| 45. | TisB insertion into the membrane is thought to result in a loss of membrane potential.
|
| 46. | It causes hyperkalemia, which stops the heart by inducing depolarization of cellular membrane potentials.
|
| 47. | Action potentials are triggered when enough depolarization accumulates to bring the membrane potential up to threshold.
|
| 48. | Thus, the membrane potential affects the permeability, which then further affects the membrane potential.
|
| 49. | Thus, the membrane potential affects the permeability, which then further affects the membrane potential.
|
| 50. | This causes the membrane potential to rise at a rate of about 300 V / s.
