presynaptic terminal การใช้

• Partial blockage of the receptor leads to retraction of corresponding presynaptic terminals.
• Their neuroligin partners can induce presynaptic terminals by recruiting neurexins.
• Voltage-gated Ca 2 + channels are located within the presynaptic terminal.
• Neurotransmitters are stored in readily releasable pools of vesicles confined within the presynaptic terminal.
• When an action potential reaches a presynaptic terminal, it activates the synaptic transmission process.
• The hypothesis predicts that regions with numerous prospective presynaptic terminals will attract more growing dendrites.
• Neurexins are diffusely distributed in neurons and become concentrated at presynaptic terminals as neurons mature.
• The target of this neurotoxin is at the presynaptic terminal, where it blocks release of acetylcholine.
• After release into the synaptic cleft, monoamine neurotransmitter action is ended by reuptake into the presynaptic terminal.
• This prevents interaction between the acetylcholine released by the presynaptic terminal and the receptors on the postsynaptic cell.
• They are usually located in specialized structures called presynaptic terminals, found at the tips of nerve cells.
• This means there is insufficient calcium ion influx into presynaptic terminal resulting in reduced exocytosis of acetylcholine containing vesicles.
• The presynaptic terminal bouton is filled with vesicles containing acetylcholine and a neuropeptide called calcitonin gene-related peptide.
• When an action potential arrives at the synapse's presynaptic terminal button, it may stimulate the release of neurotransmitters.
• The release of glutamate was also reduced in presynaptic terminals by processes that involve modulation of intracellular Ca 2 + release.
• This protein which is normally found in the presynaptic terminals and is thought to be involved in synaptic transmission in dopaminergic neurons.
• The protein is found in many regions of the brain, in the cytoplasm of neurons as well as in presynaptic terminals.
• Indeed, operation of a chemical synapse relies on release of neurotransmitter, which is stored in vesicles in the presynaptic terminal.
• They inhibit monoamine oxidase, the enzyme that metabolizes the monoamine neurotransmitters in the presynaptic terminals that are not contained in protective synaptic vesicles.
• This glutamine is then supplied to the presynaptic terminals of the neurons, where glutaminases convert it back to glutamate for loading into synaptic vesicles.
