Where does neuron charge build up before fired to the axon?
Before a neuron fires, the charge builds up at the axon hillock, the region where the axon meets the cell body (soma). This area integrates incoming signals from dendrites and determines whether the threshold for firing an action potential is met. If the threshold is reached, an action potential is generated, and the electrical signal travels down the axon.
What does an action potential refer to as?
An action potential is basically the message which is sent by the neuron down the axon towards synapse.In other words it is the impulse or the electrical signal that travels along the axon due to difference in the positive and negative charges inside and outside of the axon wall.
The depolarization of a neural membrane creates a?
The depolarization of a neural membrane creates an action potential, which is a brief electrical charge that travels down the axon of a neuron. This action potential is crucial for transmitting signals between neurons and ultimately forms the basis of communication in the nervous system.
Where does the action potential occur on a neuron?
The action potential occurs at the axon hillock, which is the initial segment of the axon where the cell body transitions into the axon. This is where the threshold potential is reached and an all-or-nothing electrical signal is generated and propagated down the axon.
What does the movement of the action potential along the axon resemble?
The movement of the action potential along the axon resembles a wave traveling down a series of interconnected nodes, similar to a domino effect. When an action potential is initiated at the axon hillock, it causes a rapid depolarization that triggers adjacent segments of the membrane to depolarize in turn. This process occurs in a cascading manner, resembling the propagation of a wave, as the electrical signal travels down the axon toward the axon terminals. The myelin sheath further enhances this effect by allowing the action potential to jump between nodes of Ranvier, increasing the speed of transmission.
An electrical impulse moving down an axon is called what?
An electrical impulse moving down an axon is known as an action potential.

What is the path of an electrical impulse as it moves through a neuron?
The electrical impulse travels into the dendrites, the "input" of the neuron, and into the soma or "body" where the signal gets processed. From there, the processed signal travels down the axon or "output" and into the dendrites of another neuron.
What does an action potential refer to as?
An action potential is basically the message which is sent by the neuron down the axon towards synapse.In other words it is the impulse or the electrical signal that travels along the axon due to difference in the positive and negative charges inside and outside of the axon wall.
What A wave pattern travels down the length of the axon of a cell.?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.
What are the steps in the generation of an action potential?
1. electrical signals are sent through nerves. 2. Travels down axon. 3. k+ +Na+ ions flow down concentration gradients to restore equilibrium.
A wave pattern travels down the length of the axon of what kind of cell?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.
What is the very beginning of the axon called?
The very beginning of the axon is called the axon hillock. It is where the electrical signals from the cell body are gathered and then transmitted down the axon.
What Process describes how a signal travels from one end of a neuron to the other end?
The process of signal transmission along a neuron is called "neuronal propagation." It occurs as an electrical signal travels from the dendrites to the cell body, down the axon, and finally to the axon terminals where neurotransmitters are released to communicate with other neurons.
The depolarization of a neural membrane creates a?
The depolarization of a neural membrane creates an action potential, which is a brief electrical charge that travels down the axon of a neuron. This action potential is crucial for transmitting signals between neurons and ultimately forms the basis of communication in the nervous system.
A nerve impulse starts at the dendrite then travels to the?
cell body, continues down the axon, and finally reaches the axon terminal. At the axon terminal, the impulse triggers the release of neurotransmitters to communicate with other neurons or muscles.
How does a neurone work?
they send electrical pulses down the axon to the next neuron.
