Amongst the neuro-transmitter substances, Acitylcholine is there which is secreted in the synaptic region of axons and muscle-fibres since there is no phyiscal gap between them. Their main function is to pass the stimulation to the nerve fibre.

Is lightning flashing across the sky a chemical or physical change?
Physical Change.
What is the chemical activity of substance?
the chemical activity of a substance is that when pink unicorns run across the sky they turn into frogs so there for they are changing int a different
How much does chemical straightening cost on average across the US?
Chemical Straightening costs vary based on the length of your hair, but it ranges from $80 to $140.
Is osmosis a physical or chemical change?
Physical. The water is not changed chemically, it is just moved by diffusion across a membrane.
Do the chemical symbols for elements vary with different languages and alphabets?
No. The chemical symbols for elements are standard across any language. For example Fe = Iron in English as well as in Chinese or Hebrew.
Neurotransmitters are chemical messengers that travel across the?
synaptic gap
The neural message being delivered in a synaptic transmission is carried across the synaptic gap by?
Chemical Substance
Which is the space that separates two neurons?
Synapses
What is the space between neurons across which chemical messages pass?
synaptic gap
Neural transmission across a mammalian synaptic gap is accomplished by?
impulses causing the release of a chemical signal and its diffusion across the synapse.
What role does acetylcholine play in neurotransmission?
Neurotransmitters diffuse across the synaptic cleft to bind to membrane receptors on the next neuron. This initiates a synaptic potential.
What chemical substance carries information across the synaptic gap to the next neuron?
neurotransmitters
How does a message jump across the synaptic gap and passes to the next neuron?
Nerve impulses, which are electrical, do not jump across the synaptic gap at synapses. Instead, the arrival of a nerve impulse at the axon terminal triggers the release of chemicals called neurotransmitters from the axon terminal into the synaptic gap, the nerve impulses then travel across the chemicals to the place where it needs to go to
Is there any synaptic delay in communication from pre-synaptic neuron to post-synaptic neuron?
Yes, when speaking of a chemical synapse; but no, not so much, when speaking of an electrotonic (gap junction) synapse.There are two types of synapses in the nervous system: chemical synapses, and electrical synapses (also know as electrotonic synapses or gap junctions).Chemical synapses have a small gap between two neurons, called the synaptic cleft, about 30nm across. At this gap, the two neurons do not touch (except for small molecules projecting from each and sticking to one another so as to keep the neurons in place to maintain the synapse; they are called synaptic adhesion molecules); the two neurons do not exchange their interior cellular fluid, the cytosol, nor any ions or other solutes. On receipt of a neural impulse, the pre-synaptic neuron releases Neurotransmitter chemicals into the synaptic cleft, which then diffuse across the synaptic cleft to the post-synaptic neuron, where they fit into receptors there and cause ligand-gated ion pores to open in the post-synaptic neuron, allowing sodium ions into it, which is the beginning of the neural signal in that neuron. The release of the neurotransmitter, its diffusion across the gap, the opening of the ligand-gated ion pores, and the entry of sodium ions takes a comparative long time, with the result that the synaptic delay for a chemical synapse is approximately 2 ms.Electrical synapses have a much smaller gap between neurons, about 3.5nm, with pore structures spanning the gap, which allows ions in the pre-synaptic neuron to pass directly into the post-synaptic neuron. Since there is no need for the pre-synaptic neuron to release neurotransmitters, nor for them to diffuse across a comparatively large gap, nor to cause ligand-gated pores to open, the synaptic delay for an electrical synapse is shorter, approximately 0.2ms.However, the difference in synaptic delay between chemical and electrical synapses may be less for mammals than for cold-blooded animals.
How does a message. travel across the gap. at a synapse?
it is sent through the neurotransmittersAt the synaptic terminal an electrical impulse will trigger the migration of vesicles containing neurotransmitters toward the presynaptic membrane.
What happens to the neurotransmitter once it is released?
Neurotransmitter diffuses across the synaptic cleft to bind to the receptor on the muscle or next nerve.It is then broken down and absorbed back into the nerve.NovaNET answer: quickly destroyed..........Good Luck :)
What reactions leap across synapses?
Reactions don't leap across synapses but neurotransmitters will diffuse across the synaptic cleft.
