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.
Where is the nerve impulse received in a neurone?
The nerve impulse is received in a neuron at the dendrites, which are the branching extensions of the cell body. Dendrites contain receptors that detect signals from other neurons or sensory stimuli. Once the signal is received, it generates an electrical impulse that travels toward the cell body and down the axon 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.
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.
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.
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.
Where is the transmission filter on 2001 Acura MDX?
The transmission filter on a 2001 Acura MDX is located inside the transmission pan. To access it, you typically need to drain the transmission fluid and remove the transmission pan. Once the pan is off, the filter can be found attached to the transmission body, and it can be replaced during this process. Always consult a repair manual or a professional for detailed instructions specific to your vehicle.

Where is transmission filter located on 2004 Kia Optima?
The transmission filter on a 2004 Kia Optima is located inside the transmission pan. To access it, you typically need to remove the transmission pan by draining the transmission fluid and unbolting the pan from the transmission housing. Once the pan is removed, you'll find the filter attached to the transmission body, which can then be replaced. Always consult the vehicle's service manual for specific instructions and safety precautions.
Where is the transmission filter located at on a Mitsubishi diamante?
The transmission filter on a Mitsubishi Diamante is typically located inside the transmission pan. To access it, you usually need to drain the transmission fluid and remove the pan, which may involve unbolting it from the transmission housing. Once the pan is removed, you can find the filter mounted inside the transmission. Always refer to the vehicle's service manual for specific instructions and safety precautions.
