What causes the synaptic delay?
The cause of synaptic delay is attributed mainly to the time needed for the synaptic vesicles to release neurotransmitter into the synaptic cleft. While it can be considered a combination of binding to the presynaptic membrane (which is relatively a transient process) and subsequent exocytosis of the neurotransmitter, the main factor is release. Additionally, it does take a very short period of time for the neurotransmitter to diffuse across the synaptic cleft and bind to to its receptors on the post-synaptic membrane.
A nerve poison that blocked neurotransmitter receptors on the dendrites would?
prevent transmission across the synaptic cleft
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.
How do electrical impulses go across synapses?
An electrial nerve impulse travels across a synapse by diffusion. The neurotransmitter substance from the pre-synaptic cleft travels across the synapse via diffusion. This is then received by receptors in the post synaptic cleft
What does the neurotransmitter bind to after it moves across the synaptic cleft?
It becomes reabsorbed by the sending membrane.
What are the principles of synaptic transmission?
Calcium ions enter the presynaptic neuron resulting in the release of neurotransmitter from the per-synaptic membrane. The neurotransmitter diffuses across the synaptic cleft, fusing with the receptors of the post-synaptic membrane. This changes the sodium channels to open and sodium ions will to flow into the post-synaptic neuron, depolarizing the post-synaptic membrane. This initiates an action potential. After the post-synaptic neuron has been affected, the neurotransmitter is removed by a type of enzyme called cholinesterase. The inactivated neurotransmitter then returns to the pre-synaptic neuron.

What word belongs to this definition move across a gap?
If it's a synaptic gap then the answer would be neurotransmitter.
What function does synaptic vesicles containing neurotransmitter?
To send a signal to the next neuron ... across the synapse.

Example of neurotransmitter?
Neurotransmitters are chemicals that transport information across the synaptic cleft between neurons. These chemicals are utilized to send a wide variety of messages. The three main types of neurotransmitters are monoamines, amino acids, and peptides.
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 does the neurotransmitter bind to after it moves across the synaptic cleft?
It becomes reabsorbed by the sending membrane.
How do nerves impulse's across the synapse?
Most neurons have a chemical synapse, which is to say that a substance called a neurotransmitter is released from the first neuron (called pre-synaptic) to the next neuron called (post-synaptic). How is the release triggered? When an action potential reaches the terminus (end of the axon) there are specialized calcium channels that are opened (voltage-gated). The calcium bind so the inner membrane and triggers the release of small membrane bound vesicles which spill out their contents of neurotransmitter into the synaptic cleft. The neurotransmitter binds to specific receptors on the post-synaptic membrane and that causes the action potential to propagate on (or for the neurotransmitter to cause an action like a muscle contraction).
Is insulin a neurotransmitter that affects growth?
No. Its a cellular membrane trigger that causes cells to transport sugar across the membrane ( via transport proteins).
