MUSCLE PHYSIOLOGY

Detailed explanation-1: -The electrical potential difference across the resting plasma membrane is called as the resting potential. Its value is −70 mV.

Detailed explanation-2: -Across the cell membrane of each neurone there exists a small difference in electrical charge, known as the membrane potential. In electrically inactive neurones, this is known as the resting membrane potential. Its typical value lies between-50 and-75 mV.

Detailed explanation-3: -Resting potential is the electric potential difference across the resting plasma membrane. This is developed due to the unequal distribution of ions across the membrane. The unequal distribution of charges or ions is due to the fact that the membrane has different permeability for different types of ions.

Detailed explanation-4: -The relative excess of positive charges outside and negative charges inside the membrane of a nerve cell at rest is maintained because the lipid bilayer acts as a barrier to the diffusion of ions, and give rise to an electrical potential difference, which ranges from about 60 to 70 mV.
