Which part of the neuron can propagate an action potential?
The axon is the part of the neuron that can propagate an action potential. This process relies on the opening and closing of ion channels along the axon membrane to allow the action potential to travel from the cell body to the axon terminals.
Which part of the neuron is capable of generating an action potiental?
The axon hillock is the part of the neuron that is capable of generating an action potential. It integrates incoming signals from the dendrites and, if the threshold is reached, triggers the action potential to be propagated down the axon.
What part of the neuron can conduct an action potential?
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.
Why causes the neurons fire?
Neurons are nerve cells, and they fire to relay messages from neuron to neuron. Neurons fire when a charge jumps across a synapse to the dendrite of a cell. The neuron then fires the charge down it's axon, and the charge travels to the next neuron.
What does propogation of an action potential mean?
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.

Where does an action potential start?
Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.

What part of a neuron relays signals from one neuron to another neuron or to an effector?
The axon terminals of a neuron are responsible for relaying signals from one neuron to another neuron or to an effector, such as a muscle or gland. When an action potential travels down the axon, it triggers the release of neurotransmitters at the axon terminals, which then stimulate the next neuron or target cell.
What part of a neuron attaches the cell body to the axon?
The part of a neuron that attaches the cell body to the axon is called the axon hillock. It is located at the base of the cell body and is responsible for integrating incoming signals to generate an action potential.
What is an initial segment of a nerve impulse?
Axon hillock- a pyramidal shaped region where all axons originate fromInitial segment- an area just beyond the axon hillock where all the stimulatory and inhibitory signals coming into the neuron are algebraically summed and it is decided whether or not an action potential should propagate or not.-----The above describes the structure of the axon where the action potential is created.However, the actual nerve impulse (action potential) is generated in a series of steps based on how the ion channels trigger.In this respect the first segment of the nerve impulse is the stimulus, which has to trigger positive ion influx beyond a given threshold.After that stimulus exceeds the threshold, it triggers the opening of ion channels which pump sodium ions into the axon and potassium ions out, thus increasing the net positive charge on the inside of the neuron, depolarizing it and initiating the action potential (the nerve impulse).
What is main part of neuron?
There are several key parts to a neuron: dendrites, which receive input, cell body or soma, where the electrical impulses sum, axon, the structure along which the action potential is propagated, and the terminal buttons which release neurotransmitters into the synapse between two neurons.
What part of the neuron contains the cell nucleus provides nourshiments and decides whether or not to fire?
The cell body, or soma, of the neuron contains the cell nucleus which is responsible for regulating the cell's activities. It also integrates incoming signals and decides whether or not to generate an action potential, the electrical signal that travels down the neuron.
The part of the neuron that decided if the message will travel to the next neuron or not is the what?
The axon terminal is the part of the nerve responsible for sending the message at all. Not only does it send the message, though, it has branching paths which allow it to determine which path it'll go on.
