"The Neuron"
Briefly describe the concept of action potential.
Answers
Answer:
The concept of action potential is a nerve impulse that begins when the inside of a neuron becomes positive enough to reach its threshold potential so that the sodium channels burst open and positive sodium ions flow into the neuron while the positive forces other positive ions, like potassium, to flow out of the neuron. The neuron then returns to its resting potential.
An action potential can be defined as the rapid rise and then the fall of the membrane potential or voltage in a pattern that is characteristic. It is a method of cell-cell communication in the body.
An Action potential has three stages - Depolarization followed by repolarization and then hyperpolarization.Depolarization is known as the rising phase during which the sodium ions (positively charged) rush out of the voltage-gated channels present in a neuron. The membrane develops a voltage of +40mV.Repolarization refers to the falling phase during which the voltage-gated sodium channels slowly close and the potassium channels open. The membrane restores the negative potential.Hyperpolarization is the last stage of an action potential during which the potassium channels remain open while the sodium channels reset.An action potential is a way of communication between the cells of the body that is carried out by the neurons.
