The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
What else can I help you with?
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from a neuron to an effector cell?
Neurotransmitter.
If an impulse traveled down one neuron but failed to move on to the next neuron what happened to the first neuron?
Vesicle are not fusing with the membrane and releasing neurotransmitter.
What effects do neurotransmitters from the neuron have on the next neuron?
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
A chemical released from one neuron to another is?
A neurotransmitter.
What carries a nerve impulse from one neuron to annother?
Neurotransmitter.
If an impulse down one neuron but failed to move on to the next neuron what is wrong with the first neuron?
It is possible that nothing is wrong with the first neuron and that the second neuron has been desensitized, or if it is the first neuron then vesicles are not fusing with the membrane and releasing neurotransmitters. This could be because a toxin has damaged the proteins that control vesicle integration, or because the calcium channels have been blocked, or in the lab setting the terminal may have run out of neurotransmitter.
The tutor asks the students what determines whether a neurotransmitter will have an inhibitory or excitatory effect on the synaptic process. One student answers that it depends on the nature of the ne?
The effect of a neurotransmitter is determined by the type of receptors it binds to on the postsynaptic neuron. If the neurotransmitter activates ion channels that allow positive ions to flow into the neuron, it typically has an excitatory effect, leading to depolarization. Conversely, if it opens channels for negative ions or closes channels for positive ions, it results in hyperpolarization and an inhibitory effect. Thus, the same neurotransmitter can have different effects depending on the receptor type and the ions involved.
Which ions causes neurotransmitter vesicles to fuse with the axons membrane during the conduction of a nerve impulse from one neuron to the next?
I believe it's Na+
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from one neuron to an effector cell?
a neurotransmitter such as acetylcholine, or dopamine. Even a neuropeptide.They will cause a receptor gated channel to open post synaptically
When one neuron wants to stimulate another it will?
A neuron releases a chemical called a neurotransmitter that will signal other neurons.
Which ion causes neurotransmitter vesicles to fuse with the axon's membrane during the conduction of a nerve impulse from one neuron to the next?
Calcium ions are responsible for triggering the fusion of neurotransmitter vesicles with the axon's membrane during the conduction of a nerve impulse. The influx of calcium ions into the neuron's terminal triggers the release of neurotransmitters into the synaptic cleft.
When an electrical signal reaches the end of one neuron How is the signal picked up by the next neuron?
There is a closed space between them. It is called as synapse. A chemical is released in this space called neurotransmitter. Over 50 are identified but there may be several hundred of them. Most common are acetylcholine, noradrenaline, adrenaline, serotonin, dopamine, histamine, glycine, aspartate, glutamate etc. Acetylcholine is destroyed in milliseconds by an enzyme acetylcholinesterase. Noradrenaline is taken up back. So with the help of neurotransmitter signals are passed to next neuron.
