Communication within a neuron is electrical while communication between neurons is chemical.?
Yes, that's correct. Within a neuron, communication occurs through electrical signals that travel along the neuron's axon. When these signals reach the synapse (junction between neurons), they trigger the release of chemical neurotransmitters that carry the signal to the next neuron.
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.
Explain the communication process of neurons in the brain?
When transmitting a message, a signal travels through the neuron until the cell ends at the terminal. In order to propagate the signal to the next neuron chemical messengers (neurotransmitters) are released into the inter-neuronal space (synapse). This triggers signal initiation in the second neuron.
What function does synaptic vesicles containing neurotransmitter?
To send a signal to the next neuron ... across the synapse.
How does a message travel from one neuron to the next?
It travels from the brain to the Spinal Cord.
How does a message travel through a single neuron?
When a message gets sent to a neuron from the dendrite it goes through the cell body to the tip of the dendrite where it leaps to the next dendrite.
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.
What effect do neurotransmitter from one 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.
What part of the brain has branching fingers that receive signals?
The neuron has dendrites that receive signals from other cells and axons that bring the signal to the next cell.
What is released when an impulse reaches the end of a neuron?
The impulse ends in the terminal or synaptic knob. Here neurotransmitters are put in vesicles and travel across the synaptic cleft to the next neuron.
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.
What does the axon bulb do?
It starts the transmission of a neural signal from one neuron to another.An axon ends in an axon terminal, which ends in a small rounded tip called the axon bulb. Each terminal lies very close to either a dendrite or a cell body of another neuron, and the combination of the end of the first neuron, the beginning of the next, and the space between them is known as a synapse; when a neural impulse reaches the axon bulb, it is stimulated to release chemical messengers called neurotransmitters into the synaptic cleft (gap), which diffuse over to the second neuron, conveying the signal to the second neuron.
