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.


How is an impulse communicated from nerve cell to nerve cell?

Via chemical messangers that cross the synapse.


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 an impulse cross a synape?

An electrical impulse travels along a nerve until it hits a synapse, where it causes the release of chemicals (neurotransmitters) which migrate across the synapse. At the other side , these neurotransmitters activate receptors which cause an electrical signal to continue along the nerve.


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.


State why there is a brief delay in the transmission of an impulse across the synapse?

The impulse must go from one neuron to the next. To do this, it must change from an electrical to a chemical signal, and back to an electrical signal when it reaches the next neuron. Electrical signals are impossibly fast, but neurotransmitters cannot cross a synapse that fast. So, the impulse is at its slowest point when it crosses the synapse.


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.


How do nerve impulses cross the gap between nerve cells?

When an electrical signal, or impulse, reaches the end of an axon it triggers chemicals called transmitters. The electrical signals then become chemical ones as the transmitters cross the synapse, the gap between an axon and a dendrite. When they reach the dendrite of another neuron they spark a new electrical signal that then travels the length of that nerve cell. And it does this over and over until it reaches its destination.


Can you briefly describe the events that occur when a nerve impulse arrived at a synapse?

A synapse is a junction where two nerves meets. when action potential reaches a synapse, the pores open allowing an afflux of calcium ions into presynaptic terminal. this causes neuro transmitters to be released and cross over the synaptic cleft to attach to receptors in the post synaptic membrane and allow impulse to pass.


How do impulses cross synapse between neurons?

By a chemical released by an axon.


How does an impulse cross a synaptic gap between two nerve cells?

When an action potential reaches the end of a neuron, it triggers the release of neurotransmitters into the synaptic gap. These neurotransmitters then bind to receptors on the neighboring neuron, causing ion channels to open and allowing the impulse to continue along the second neuron. The neurotransmitters are then either broken down or taken back up by the original neuron to end the signal.


How does the signal travel from one neuron to the next in the human brain?

The signal travels from one neuron to the next in the human brain through a process called synaptic transmission. When an electrical impulse reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters. These neurotransmitters then cross the synapse, a small gap between neurons, and bind to receptors on the receiving neuron, causing it to generate a new electrical signal and continue the message transmission.
