The propagation of an action potential along an axon, away from the soma. [GOC:isa_complete]
Neuronal action potential propagation is a fundamental process in the nervous system, enabling rapid communication between neurons. It involves a sequence of events that transmit electrical signals along the axon, the long, slender projection of a neuron. Here's a detailed breakdown:
1. **Resting Membrane Potential:** In its resting state, the neuron maintains a negative electrical potential inside the cell compared to the outside. This is due to an uneven distribution of ions, primarily potassium (K+) and sodium (Na+) ions, across the cell membrane. The membrane is selectively permeable, allowing some ions to pass more easily than others.
2. **Stimulus and Depolarization:** An action potential is initiated when a neuron receives a stimulus, such as a neurotransmitter binding to its receptors. This stimulus triggers the opening of sodium channels in the membrane, allowing Na+ ions to rush into the cell. This influx of positively charged ions causes the membrane potential to become less negative, moving towards a positive value. This process is known as depolarization.
3. **Threshold Potential:** If the depolarization reaches a critical threshold, the neuron fires an action potential. This threshold is typically around -55 mV.
4. **Rising Phase (Upstroke):** Once the threshold is crossed, a positive feedback loop is activated. More sodium channels open, further increasing the influx of Na+ ions. This rapid depolarization causes the membrane potential to spike rapidly, reaching a positive peak.
5. **Peak Potential:** The membrane potential reaches its maximum positive value, typically around +40 mV. At this point, sodium channels begin to close, while potassium channels open.
6. **Falling Phase (Repolarization):** Potassium channels open, allowing K+ ions to flow out of the cell. This efflux of positively charged ions causes the membrane potential to decrease rapidly, returning towards its resting value.
7. **Undershoot (Hyperpolarization):** The membrane potential may temporarily become more negative than the resting potential due to the continued outflow of K+ ions. This period is known as hyperpolarization.
8. **Refractory Period:** During this period, the neuron is less likely to fire another action potential. It ensures that signals are transmitted in one direction and prevents the backflow of action potentials.
9. **Return to Resting Potential:** Sodium-potassium pumps actively transport Na+ ions out of the cell and K+ ions back in, restoring the original ion balance and returning the membrane potential to its resting state.
10. **Propagation Along the Axon:** The action potential doesn't stay localized at the initial site of stimulation. It travels along the axon like a wave, triggering a chain reaction of depolarization. The influx of Na+ ions at one point depolarizes the adjacent region, causing it to reach threshold and fire its own action potential. This process repeats along the length of the axon, allowing the signal to be transmitted over long distances.
11. **Myelin Sheath:** In many neurons, the axon is covered by a myelin sheath, a fatty insulating layer. This sheath significantly increases the speed of action potential propagation by reducing the leakage of ions across the membrane and concentrating the depolarization at specific points called nodes of Ranvier. This type of propagation is known as saltatory conduction.
12. **Synaptic Transmission:** When the action potential reaches the end of the axon (the axon terminal), it triggers the release of neurotransmitters. These chemical messengers cross the synaptic cleft, the small gap between the neuron and its target cell, and bind to receptors on the target cell. This binding can initiate a new action potential in the target neuron or stimulate other cellular processes.
Neuronal action potential propagation is a crucial process for communication in the nervous system, enabling the transmission of information from the brain and spinal cord to various parts of the body, allowing for sensory perception, motor control, thought, and many other vital functions.'
