Once the electrical, within-neuron signal starts, it will continue to the terminal end of the neuron in an all-or-none fashion, unless influenced by another neuron. For example, an inhibitory (e.g., GABA-ergic) neuron can stop or weaken the electrical signal in the first neuron (e.g., by increasing chloride influx). Once the neuron releases its transmitter, though, the transmitter has been released; however, that chemical signal can be modified either post- or pre-synaptically by action at the receptors.

What is the path of a nerve impulse from your leg to your brain and back to your leg?
A nerve impulse travels from your leg to your brain through sensory neurons. Once in the brain, the impulse is processed, and a response is generated. The response travels back to your leg through motor neurons to initiate movement or action.
The message that travels through a neuron?
The message that travels through a neuron is an electrical impulse called an action potential. It is generated when the neuron is stimulated and travels along the neuron's axon, facilitated by the movement of charged ions. This ultimately allows the neuron to communicate with other neurons or target cells.
Why the transmission of nerve impulse is faster in medullated nerve fiber than in non-medullated nerve fiber?
generally the impulse is nothing but the stimulus carried to a part of body to carry out specific action in response to that stimulus.it is transmitted from one neuron to another or one neuron to another organ.this is carried all along the neuron and at the end that is at the synapse it gets diffused in neurotransmitter and again transmitted to another organ or neuron.this is carried very faster.this is started polarization of neuron and once polarized and being transmitted it cant be again polarizedthis occurs even more fastly in .mylenated neurons than in nonmylenated.bec in mylenated neurons the axon is partly covered by myleinshreath.this myleinshreath has a special property that it doesn't allow ions to pass through it.since polarization is occurred due to movement of ions in and out of axons,and the mylein shreath doesn't allow this the leaping of ions occurs.and as a result impulse been transmitted as a loop of current by taking leap at mylein shreath.while in nonmylenated ones no such leaping occurs and it is transmitted slowly all along the length of axon.so impulse transmission occurs very fast in mylenated ones.
How does the all or none principle relate to the transmission of a nerve impulse?
The nerve impulse (action potential) either occurs, or it doesn't, depending on whether or not a sufficient summation of inputs from dendrites at the axon hillock (the trigger point) has occurred, either temporally or spatially.That is, if a large enough number of dendrites have received inputs from other neurons such that their total contribution of electrotonic impulses to the axon hillock results in enough Na ions there to trigger the action potential, or, if one or more dendrites is/are stimulated so often or quickly that, again, there are enough Na ions pushed to the axon hillock to trigger the action potential, then the nerve will "fire". If not enough Na ions are caused to congregate at the axon hillock by either means, then the action potential will not occur, and there will be no transmission of a nerve impulse.
What are neuronal endings?
Neuronal endings, also known as axonal terminals, are the tips of axons that make connections with other neurons, muscles, or glands. These structures play a critical role in transmitting information between neurons by releasing neurotransmitters across the synapse. Neurotransmitters allow for communication and signal transmission within the nervous system.
Would the pivot bearing stop the car from going into gears once the car is started?
The pivot bearing can cause your car from going into gear, once the car is started. The pivot bearing is located in the transmission.
Is Judo awesome?
to someone who has just started it's always horrible and scary but once you learn how to break fall.
When was Once You Get Started created?
Once You Get Started was created in 1975.
Explain the transmission of the electrical impulse within the heart from where it begins in the right atrium to where it ends within the ventricles?
The electrical impulse in the heart begins in the sinoatrial (SA) node and travels across the walls of the right atrium to the atrioventricular (AV) node. WHie the impulse travels the atria have time to contract. Once the impulse hits the AV node the signal is transmitted to the Bundle of His (AV bundle) and then on the the intraventricular fibers (purkinje fibers) in the septum and the outer chamber walls of the heart . This results in a simultaneous ventricular contraction.
My 1995 northstar Seville sls transmission spits fluid back out through dipstick once engine is started what do you think the problem is?
You have a buildup of pressure in the transmission which may be because it is overfull of transmission fluid. I would advice you to immediately take it to a professional, before some serious damage is done.
Where is the transmission filter in a 94 suzuki sidekick?
inside the transmission. visible once you remove the transmission pan

What is a sentence for impulse using a semicolon?
It is certainly unethical to use wikianswers.com to complete one's english homework; despite this, however, thousands of students get the impulse to cheat every day.
When did dawn fraser start swimming?
once a famous swimmer, always a famous swimmer
What would cause a 97 Chevy Silverado to not shift into gear once started?
That is one of the signs that your transmission is going bad. Better have it checked at your local mechanic before it leaves you stranded.

What color is burned transmission fluid?
Typically, it'll be black or something close to it once its burned. It always appears brownish to me and has a very bad smell. The smell more than anything let's you know the transmission have overheated and the fluid has been burnt.
