Short note on :Resting potential of a nerve fibre.

1.	Short note on :Resting potential of a nerve fibre.
Answer» 1. The neurons have a property of excitability. 2. The transmission of the nerve impulse along the long nerve fibre is a result of electrical changes across the neuronal membrane during conduction of an excitation. 3. The plasma membrane separates the outer [extra cellular fluid] and inner solutions [intra cellular fluid/cytoplasm] of different chemical compounds. 4. The external tissue fluid has both Na⁺ and K⁺ 5. On the inside there is an excess of K⁺ along with large amount of negatively charged protein molecules and nucleic acid. 6. This condition of a resting nerve is also called a polarised state and it is established by maintaining an excess of Na+ on the outer side.
