(a) Define the term equilibrium potential and use the Nernst equation (see Appendix) to show how the equilibrium potentials for both sodium and potassium are calculated. Equilibrium potential is the potential of the membrane when there is no net flow of ions from one gradient to the other gradient. The ions are equal and are opposite of each other but not moving from one side to the other. Sodium: Ena=2.303((8.31 J m-1 K-1)(310K))/((1(= 9.65 x 104 c m-1))(log(150/15))= 61.54 mV Ek=2.303((8

carries important information through action potential‚ this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons
