What molecule 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
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.
What do the bubbles of chemical crossing the synapse do?
Chemicals called neurotransmitters move across the synaptic gap by diffusion and carry a neural signal across to the receiving neuron. But the 'bubbles' (vesicles) which contained the neurotransmitter chemicals do NOT themselves cross the synaptic gap, they just release the neurotransmitters into the synaptic gap. (The neurotransmitters move across the synapse, the vesicles do not.)The vesicles release their contents of neurotransmitters into the synaptic gap by a process called exocytosis, in which the neural impulse which reaches the terminal button of the presynaptic neuron causes voltage-gated calcium ion pores to open, allowing an influx of calcium ions, which leads to the fusing of the vesicles to the cell membrane, which amounts to the vesicles 'turning themselves inside out' as the membrane of the vesicle merges with the cell membrane, which expels the neurotransmitters into the synaptic gap.The neurotransmitters flow across the synapse to bind with the postsynaptic neuron, potentially triggering neuron excitation (firing) or inhibition (preventing firing).
This contains neurotransmitter that allow. Signal to cross from on neuron to another?
Synaptic Vesicles contain neurotransmitters that travel in as per with potential gradience to transmit information
What does the synaptic knobs of the presynaptic neuron contain synaptic vesicles loaded with?
To provide energy for the re-combination of Choline and ethanoic acid, to form Acetylcholine. Acetylcholine is used as a neurotransmitter, and gets broken down after its reached the sodium channels' receptors on the post-synaptic membrane by acetylcholinease.

Neurotransmitter.
What molecule 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
Which structure contains vesicles with acetylcholine?
Synaptic vesicles in the neuromuscular junction contain acetylcholine (ACh) which is the neurotransmitter for initiating muscular contractions.
What function does synaptic vesicles containing neurotransmitter?
To send a signal to the next neuron ... across the synapse.
Where is neurotransmitter stored?
Neurotransmitters are stored in synaptic vesicles in the terminal bouton of pre-synaptic axons. They are released from the terminal bouton into the synaptic cleft and the neurotransmitters exert their action on the post-synaptic neurons.
Is it the synaptic cleft that contains vesicles filled with acetylcholine?
The synaptic knob contains vesicles filled with neurotransmitters. Therefore, Acetylcholine is the neurotransmitter that stimulates skeletal muscle to contract. It is released into the synaptic clefts between motor neuron axons and motor end plates.
When calcium ions enter the synaptic terminal?
they cause vesicles containing neurotransmitter molecules to fuse to the plasma membrane of the sending neuron.

How do Presynaptic neurons release neurotransmitters?
They don't, the neurotransmitters stay on either side of the synapse. Neurotransmitters are released when the synaptic vesicles fuse with the presynaptic neuron's membrane, so as to release them into the synaptic cleft.
How does an impulse travel from a presynaptic neuron to a postsynaptic neuron?
When the action potential reaches the button(axon terminal) of the presynaptic neuron the depolarization causes voltage gated calcium channels to open increasing intracellular calcium content. This causes synaptic vesicles to fuse to the membrane and release neurotransmitters that bind to the post synaptic neuron and create a chemical action potential.

What is the extensions on the distal end of a neuron called?
The distal end of a neuron is the axon, an extension that arises from the soma (cell body), and at the distal end of an axon there are extensions called telodendria. At the distal ends of telodendria are knoblike structures called synaptic end bulbs (sometimes called synaptic knobs). Synaptic end bulbs have synaptic vesicles inside them that contain neurotransmitters. Synaptic vesicles are released by exocytosis into the synaptic cleft for diffusion. I can't tell from the way your question is worded if you're asking about axons, telodenria or synaptic end bulbs because all of these structures are at the distal end of a neuron. Determine what the function of the "extensions" is and use whichever part of my answer applies.
