What is the range of electrical potential in living cells Generally?

From – 60 mv to – 90 mv, depending on the cell type.

What is the range of resting membrane potential in nerve and muscle cells?

– 65 mv to – 90 mv.

Enumerate the mechanisms that contribute to membrane potential.

• Selective permeability of the membrane as the cause of membrane potential
• Electrogenic pump as the cause of membrane potential
• Presence of anions as the cause of membrane potential
