Flash! - The impulse is a jump of electricity from one neuron to the next via the dendrites. It happens in a millisecond of time so we are not even aware of it. Touch an ice cube with your finger; the signal goes from the finger to the brain and back that we get the immediate sense that the ice cube is cold.

What is a chemical impulse?

A chemical impulse refers to the rapid transmission of signals in the nervous system, primarily involving the release of neurotransmitters at synapses between neurons. When a nerve impulse reaches the end of a neuron, it triggers the release of these chemicals, which cross the synaptic gap and bind to receptors on the adjacent neuron, facilitating communication. This process is essential for various functions, including muscle contraction, reflex actions, and the overall functioning of the brain.


How does a neuron send a signal to communicate with other neurons or muscles?

A neuron sends a signal through an electrical impulse that travels down its long, slender body called an axon. When the impulse reaches the end of the axon, it triggers the release of chemical messengers called neurotransmitters. These neurotransmitters then cross the small gap between the neurons or between a neuron and a muscle cell, allowing the signal to be passed on to the next cell.


How do impulses cross synapse between neurons?

By a chemical released by an axon.


How does a nerve impulse cross the gap between the axon and the next?

Curently unknown...


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.


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.


What are the Chemicals that cross the synaptic gap and bind to receptors on another neuron called?

Synapse is a narrow gap containing communicating junction between two neurons where an axon terminal comes near contact with dendrite terminal of next neuron. A narrow fluid filled space, called synaptic cleft, occurs between the two.As the impulse reaches the presynaptic knob, it stimulates release of neurotransmitter into the cleft.


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.


What is the space between neurons where neurotransmitters cross called?

The space between neurons where neurotransmitters cross is called the synapse. It serves as the junction between two communicating neurons, allowing for the transmission of chemical signals from one neuron to another.


What structures cross the synapse to generate the next impulse?

Neurotransmitters.


Do chemotherapy drugs affect neurons?

some of the drugs can cross blood-brain barrier, so it can affect neurons too.


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

Via chemical messangers that cross the synapse.
