The impulse ends in the terminal or synaptic knob. Here neurotransmitters are put in vesicles and travel across the synaptic cleft to the next neuron.

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
When an impulse reaches the end of a neuron it tiggers the releases of?
Neurotransmitters
When a nerve impulse reaches the end of a motor neuron?
It fulfills its prime function - it turns that muscle ON - for a duration.
Why is the chemical synapses be release when a neural impulse reaches the end of an axon?
Neurotransmitters are released in order to transmit the message from the axon terminal to the other neuron by having said synapse "jump" to the neighboring dendrite.
When the what reaches the end of the axon the neurotransmitter is released?
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
Is it correct that synaptic clefts prevents an impulse from being transmitted directly from one neuron to another?
Yes, that is correct. The synaptic cleft is a small gap between neurons, and it prevents direct transmission of impulses. When an impulse reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the adjacent neuron, allowing the impulse to be transmitted indirectly.
What reaches the end of the axon when the neurotransmitter is released and diffuses to the muscle membrane to combine with receptors there?
nerve impulse
Where on a neuron does an impulse start and end?
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.
When an action potential reaches the end of a neuron it triggers the release of?
When an action potential reaches the end of a neuron, it triggers the release of neuotransmitters such as epinephrine (sympathetic) or achetylcholine (parasympathetic).
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.
Through which part of the neuron does an impulse leave the cell?
Terminal end fibers
What is the result of sodium ions moving across the axons membrane during an action potential?
a neural impulse(electrical impulse) is released and it travels down the axon of a neuron to the axon terminals. At the axon terminal there are sacs called synaptic vesicles which contain chemicals called neurotransmitters. When the neural impulse reaches the terminal it causes the sacs to move closer to the membrane of the axon terminal and release the neurotransmitters inside. Then neurotransmitters travel across the synaptic gap and stimulate the dendrites of another neuron and the whole process starts again.
