What is the sequence of events along an axon?
The sequence of events along an axon involves the generation of an action potential at the axon hillock, propagation of the action potential down the axon via depolarization and repolarization of the membrane, and neurotransmitter release at the axon terminals to communicate with other neurons or target cells.
What is a sequence of rapidly occurring events that decrease and reverse the membrane potential and then eventually restore it to the resting state?
An action potential is a sequence of rapidly occurring events that decrease and reverse the membrane potential, followed by repolarization and ultimately restoration back to the resting state. This process involves the opening and closing of voltage-gated ion channels, resulting in the propagation of electrical signals along the neuron.
What is the sequence of events that follow a threshold potential?
Following a threshold potential, voltage-gated sodium channels open, allowing sodium ions to rush into the cell, depolarizing the membrane. This triggers an action potential that spreads down the length of the neuron. Once the action potential reaches the end of the neuron, it triggers the release of neurotransmitters into the synaptic cleft to communicate with the next neuron.
Is it possible to have a partial action potential?
No, action potentials are all-or-nothing events that either reach their full potential or do not occur at all. Once the threshold is met, the action potential will propagate along the neuron without diminishing in strength.
What sequence of events occurs when an action potential arrives at the presynaptic terminal?
When an action potential arrives at the presynaptic terminal, voltage-gated calcium channels open, allowing calcium ions to enter the cell. The influx of calcium triggers the release of neurotransmitter vesicles from the presynaptic terminal into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic membrane, leading to changes in the postsynaptic cell's membrane potential.

What is sequence signals?
sequence signals are signals that are used to arrange events in proper order...! for example..the teacher is in a wrong grammar..!
Does the sequence of events in a story describe plot?
Yes, the sequence of events in a story is directly related to the plot. The plot is the series of events that make up the narrative and drive the story forward. It includes the conflict, rising action, climax, falling action, and resolution.
In a story what is the sequence of events called?
The sequence of events in a story is called the plot. It consists of the exposition (introduction of characters and setting), rising action (development of the conflict), climax (turning point), falling action (resolution of conflict), and resolution (conclusion).
What is the sequence of events that correlates to the sequence of events of a nerve impulse?
2,1,3,4
What is the sequence of events that follow a threshold potential?
Following a threshold potential, voltage-gated sodium channels open, allowing sodium ions to rush into the cell, depolarizing the membrane. This triggers an action potential that spreads down the length of the neuron. Once the action potential reaches the end of the neuron, it triggers the release of neurotransmitters into the synaptic cleft to communicate with the next neuron.
What are the major events of an action potential and what ion changes are associated with each event?
An action potential is a chain reaction of cell events caused by an ionic gradient. One example is the firing of a nerve reaction.
List the events that occur in an action potential?
In simplest terms, the five stages of action potential are... A. Action Potential B. Depolarization C. Recovery Phase D. Refractory Period E. Hyper-polarization
What is formed by the action and events of a story?
A plot is formed by the action and events of a story. It is the sequence of events that make up the narrative and drive the story forward. The plot usually includes elements such as conflict, rising action, climax, and resolution.
What best describe a plot?
the action and sequence of events in a story that are usually a series of related incidents.
What are the events that must occur to generate action potential?
Local polarization is the first step. Next the generation and propagation of an action potential. Lastly repolarization has to take place.
