Question

Discuss the factors directly affecting MAP and explain how each is affected at least 3 factors.

Answer 1

The Membrane Action Potential depends upon a number of factors:

1. Ion composition : Both the organic and inorganic charged particles and their distribution across the Membrane dictates the membrane action potential.
2. Permeability of the membrane : The inherent permeability of the membrane which is different for different ions also decides the membrane potential.
3. Ion gradient across the membrane: The difference between the concentration of an ion inside and outside the membrane is directly related to the potential.
