What accomplishes the transmission of the nerve signal across the synapse?
Wiki User
∙ 13y ago
The release of 'neurotransmitter substances' from an axon's perifery which traverse the synaptic cleft - the space between axon and adjoining dendrite - to both affect and effect the adjoining dendritic "perifery" which then re-initiates signal propagation to the next bunch of exonic nerve "endings".

Why is synapse important to the nervous system?
Synapses are important because they enable signal transmission in the body. These signals are the nerve impulses, which go across and between neurons. This process occurs in the synaptic cleft of the central nervous system.
How does the synapse work between each neuron?
There are many kinds of synapses in the nervous system, but I assume you're talking about the most commonly discussed type: the chemical synapse. These synapses join nerve cells (called neurons) and allow them to communicate.Communication across a chemical synapse is called synaptic transmission. It occurs when electrical activity (called an action potential) in the first cell triggers the release of a chemical signal (called a neurotransmitter) across the synapse. The neurotransmitter travels across the synapse by a process of diffusion, ultimately reaching its target, the second cell. There, the neurotransmitter binds a special type of protein molecule called a neurotransmitter receptor, which changes its shape in response to binding the neurotransmitter. This shape change results in a series of subsequent changes in the second cell. These subsequent changes result in alterations in the electrical activity of the second cell.The gist of synaptic transmission is that it allows the electrical activity in one nerve cell to influence the electrical activity of another.
What part of nerve cell is adjacent to neuromuscular junction?
The axon terminal of a nerve cell is adjacent to the neuromuscular junction. The axon terminal releases neurotransmitters that transmit signals across the synapse to the muscle fiber. This signal triggers muscle contraction.
When a neuron responds to a particular neurotransmitter by opening gated ion channels the neurotransmitter is serving as which part of the signal pathway?
Signal Molecule Synaptic transmission is when it moves across the synaptic gap, and it then just binds to the receptor on the other side.
What is the area between two neurons?
Area between two neurons is called a synapse.In the nervous system, a synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell.neurons are cells that are specialized to pass signals to individual target cells, and synapses are the means by which they do so.
Neural transmission across a mammalian synaptic gap is accomplished by?
impulses causing the release of a chemical signal and its diffusion across the synapse.
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 are neurontransmitters?
a chemical that transmits a nervous systems signal across a synapse.
What is the part of neuron that facilitates synoptic transmission of signal to another neuron?
synapse
What function does synaptic vesicles containing neurotransmitter?
To send a signal to the next neuron ... across the synapse.
How are synapses adapted for diffusion?
The synapse releases a chemical that can diffuse across the gap between two neurones. The synapse has a large surface area, which means diffusion of the chemical can occur at a higher rate.
What is the term for the cell that receives a signal at a synapse?
The cell receiving the signal at the synapse is called the postsynaptic neuron.
What is the small space between one neuron and the next is called?
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
How does a signal cross from the axon of the neuron to the receiving cell?
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel across the synapse. Once they reach the receiving cell, they create a new electrical signal.
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.
