Neurotransmitters send the impulse across the synapse


What is responsible for transmission of nerve impulse across a synapse?

NEUROTRANSMITTER is responsible for transmission of nerve impulses.Eg.dopamine,acetylcholine etc.


What is the space through which a nerve impulse passes from one nerve cell to another called?

A nerve impulse passes from an axon terminal of one neuron to another neuron across a synaptic gap.


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.


What is the location from which a nerve impulse is transmitted from one nerve cell to another?

synapse


What is the space through which a nerve impulse passes from one nerve cell to another?

synapse


What is the distance across a nerve synapse?

The distance across a nerve synapse is 20 nanometres or 2x10-8 metres


How do electrical impulses go across synapses?

An electrial nerve impulse travels across a synapse by diffusion. The neurotransmitter substance from the pre-synaptic cleft travels across the synapse via diffusion. This is then received by receptors in the post synaptic cleft


Space where the nerve impulse jumps from one neuron to another?

Synapse


What is the point at which a nerve impulse is sent from one nerve cell to another?

It diffuses across a small gap called a synapse between the two nerve cells. It is passed as a neurotransmitter (in chemical sacs). They reach the end of one cell and the impulse is converted into neurotransmitters, which are released from that cell, diffuse across the gap, and land on the receptor site, where they are converted back into electrical impulses.


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

Via chemical messangers that cross the synapse.
