Question

vesicles of pre-synaptic nodes contain what?

Answer 1

Hey there!


PRE SYNAPTIC NEURON  is the neuron from axon terminal which carries the electrical impulses to the post synaptic neuron through synaptic cleft by the release of neurotransmitters...

POST  SYNAPTIC NEURON is a neuron to the cell body or dendrite of which an electrical impulse is transmitted across a synaptic cleft by the release of a chemical neurotransmitter from the axon terminal of a presynaptic neuron.

heya friend!!☺☺
here's your answer!!☺☺

Vessels of pre-synaptic nodes contain neurotransmitters!!

Some examples of neurotransmitters are as follows:

Major neurotransmitters:

Amino acids: glutamate, aspartate, D-serine, γ-aminobutyric acid (GABA), glycine
Gasotransmitters: nitric oxide (NO), carbon monoxide (CO), hydrogen sulfide (H2S)
Monoamines: dopamine (DA), norepinephrine (noradrenaline; NE, NA), epinephrine (adrenaline), histamine, serotonin (SER, 5-HT)
Trace amines: phenethylamine, N-methylphenethylamine, tyramine, 3-iodothyronamine, octopamine, tryptamine, etc.
Peptides: somatostatin, substance P, cocaine and amphetamine regulated transcript, opioid peptides
Purines: adenosine triphosphate (ATP), adenosine
Others: acetylcholine (ACh), anandamide, etc.

hope it helps you!!☺☺
