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.
In what direction does an action potential move in a nerve cell?
originates in axon hillock. travels down axon to the target (i.e dendrite, another cell body, muscle fiber...)
List the cellular structures over which an impulse would pass?
In the body, an electrical impulse travels through the neurons, or nerve cells, to send signals to and from the brain. The Dendrites of the neuron accept the impulse, send it through the soma, down the axon, and to the axon terminal, where it'll be sent to the next neuron, almost instantly.
What is the function of the axon hillock?
An axon hillock is part of a neuron that acts as a bridge between the cell body and the axon. Electrical impulses from the dendrites and cell body are summed at this point, which is then sent down the axon.
How fast does an action potential travel down a myelinated nerve?
An action potential is not passively propagated down the axon. There have to be ion channels along the axon or else the action potential will gradually decay. So the the rate of that the action potential 'travels' is dependent on the passive property called the length constant of the axon (factor in capacitance, axon diameter) plus the density of ion channels.
An electrical impulse moving down an axon is called what?
The nerve that travels down a neuron axon is basically Action Potential.It is an electrochemical change that passes through the cell.
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.

A wave pattern travels down the length of the axon of a cell?
Depolarized
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.
How does a neurone work?
they send electrical pulses down the axon to the next neuron.
In what direction does an action potential move in a nerve cell?
originates in axon hillock. travels down axon to the target (i.e dendrite, another cell body, muscle fiber...)
What is action portential?
The most common type of action potential is the change in voltage down the axon of a neuron. In other words, it is an electrical signal that is sent down the axon of a nerve cell.
