The axoplasm inside the axon contains high concentration of (i) ions and low concentration of _(ii)_ ions, during the resting state of the neuron.
Identify the value of action potential.
Potential difference across resting membrane is negative. This is due to differential distribution of the following ions ______.
During resting potential, the axonal membrane is polarised, indicate the movement of +ve and –ve ions leading to polarisation diagrammatically.
What is the difference between electrical transmission and chemical transmission?
