the impulse starts at the dendrites which is located near the cell body and ends at the synaptic terminals which are at the end of the axon.

What happens when an impulse reaches the end of an axon?
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
What are the sources of stimulation that start a nerve impulse?
An impulse begins when a neuron is stimulated by another neuron or by the environment.
What is a neuron impulse?
it is neuron impulse
What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
When an impulse reaches the end of a neuron it tiggers the releases of?
Neurotransmitters
Through which part of the neuron does an impulse leave the cell?
Terminal end fibers
Where is the neuron in the body?
Neuron is the nerve cells that carry messages to the brain .The various parts of neuron are dendrite ,axon ,nucleus , cell body and nerve ending . All the information from the environment is detected by the specialised tips of nerve cells .These receptors are usually located in our sense organs such as,nose , tongue and so on. The information acquired at the end of the dendritic tip of a nerve cell sets off a chemical reaction that creates an electrical impulse . This impulse travels from the dendrite to the cell body , and then along the axon ,to its end .At the end of the axon , the electrical impulse sets of the release of some chemicals . These chemicals cross the gap or synapse, and start a similar electrical impulse in a dendrite of the next neuron . This is how nerve impulse travel in a body
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
Why would a neuron not send an impulse?
If a neuron is not sending out an impulse or signal, this means the neuron is at rest. Neurons send signals electrochemically.
When a nerve impulse reaches the end of a motor neuron?
It fulfills its prime function - it turns that muscle ON - for a duration.
What travels through the neuron?
An electrical impulse will travel through a neuron.
What begins when a neuron is stimulate by another neuron in its environment?
A nerve impulse
