An electrical signal in a neuron used to send messages in the body is called an action potential. This signal is generated by the flow of ions across the neuron's membrane when it reaches a certain threshold, leading to the propagation of the signal along the neuron.
Impulse propagation refers to the transmission of information or signals along a biological or artificial network, such as nerve cells in the human body or electronic circuits. In the context of nerve cells, it typically involves the propagation of action potentials along the axon of a neuron to transmit electrical signals. Impulse propagation plays a crucial role in communication and coordination within biological systems as well as in the functioning of electronic devices.
When the outside of the neuron cell is more positive than the inside, the cell is in a state of depolarization. This shift in electrical charge can trigger an action potential, leading to the propagation of nerve impulses along the neuron.

The speed of impulse propagation in neurons is typically around 1-100 meters per second, but can vary based on factors such as the type of neuron and the presence of myelin sheath. In cardiac tissue, the speed of impulse propagation is slower, around 0.5 to 1 meter per second.
A wave of depolarization occurs when there is a sudden influx of positive ions, typically sodium ions, into the neuron, leading to a reversal of the cell's membrane potential. This helps in transmitting electrical signals along the neuron through a process known as action potential propagation.
Neurotransmitters are chemicals released by neurons that carry signals across the synapse to stimulate the next neuron in the chain. They play a crucial role in influencing action potential propagation by either triggering or inhibiting the generation of new action potentials in the postsynaptic neuron. This process helps in the transmission of nerve signals through the nervous system.
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
The axon of a neuron is responsible for conducting an action potential. This is made possible by the presence of voltage-gated ion channels along the axon membrane that allow for the propagation of electrical signals.
Propagation of an action potential refers to the transmission of the electrical signal along the length of a neuron's axon. This is achieved through a series of depolarization and repolarization events that allow the action potential to travel in a rapid and coordinated manner from the cell body to the axon terminals. The propagation process ensures that information is effectively communicated from one part of the neuron to another.
