When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).

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
An impulse reaches the CNS from the PNS via the?
Afferent nerves
True or false when an impulse reaches a synapse an electrical spark jumps the gap?
TRUE
What is the name of the region where two neurons are in done contact is known as?
synapse is that junction through which impulse can be transmitted from one neuron to another.
What is the small gap between neurons called?
The small microscopic gabs b/w the two neurons are called "Synapse". The conduction of nerve impulse through this synapse is made possible through Neurotransmitters. As the impulse reaches at the Pre-synaptic membrane the small vesicles release these Neurotransmitters which initialize the impulse in post-synaptic membrane.
During neurotransmission when the electrical impulse reaches the end of the axon it crosses a gap called a?
The impulse itself does not actually cross the gap, which is called a synapse by the way, instead it stimulates the realease of a neurotransmitter from vesicles. When the neurotransmitter reaches the other side of the synapse it binds proteins on the opposing membrane and in doing so stimulates the membrane to continue the action potential on the mect cell.
Which one of the following phrases describes the transmission of impulses to and from nerve cells?
There is a connection between two brain cells, called a synapse. When it reaches the end of one cell, the electric impulse transforms itself into a chemical substance, and is transferred from one cell to another. When it reaches the second cell, it is again transformed intro an electric 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.
How does the impulse jump the synapse?
Chemical diffusion
A small space across which an impulse travels to move from one neuron to another?
It is most definitely a synapse.
What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
What happens to the body when the receptors that remove catecholamines from a synapse have very low activity?
No impulse is transmitted. Hence the all or nothing principal.
