Question

With reference to conduction of nerve impulse comment on the following:
1. Resting potential
2. Action potential
3. Neurotransmitter

Answer 1

HEY MATE HERE IS YOUR ANSWER

A neuron that emits an action potential, or nerve impulse, is often said to "fire". Action potentials are generated by special types of voltage-gated ion channels embedded in a cell's plasma membrane. ... This then causes more channels to open, producing a greater electric current across the cell membrane and so on.

The resting membrane potential of a neuron is about -70 mV (mV=millivolt) - this means that the inside of the neuron is 70 mV less than the outside. At rest, thereA nerve impulse is a sudden reversal of the electrical charge across the membrane of a resting neuron. ... It begins when the neuron receives a chemical signal from another cell. The signal causes gates in sodium ion channels to open, allowing positive sodium ions to flow back into the cell are relatively more sodium ions outside the neuron and more potassium ions inside that neuron
