Definition of synapse in English:

synapse

noun

  • A junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.

    • ‘In the case of motor neurons, the axon terminal finds the site of the original synapse on the muscle cell by recognizing the basal lamina that fills the synaptic cleft.’
    • ‘But a single synapse firing briefly is generally not enough to make the neuron fire an impulse, technically termed an action potential, of its own.’
    • ‘When the spike reaches the synaptic terminals it causes neurotransmitters to be released into the synapse where they then flow to post-synaptic neurons.’
    • ‘It codes for the protein in neurons that recycles secreted serotonin from the synapse.’
    • ‘Once the genes were turned on, certain proteins would be released, which reshaped the end of the nerve cell or synapse and changed how it functioned for a lengthy period of time.’
    • ‘At the end of the trunk is a synapse or connection with other items, usually roots of other neurons.’
    • ‘He found that learning occurs at the synapse (the junction between two neurons) by several means.’
    • ‘A neurotransmitter such as acetylcholine is responsible for allowing nerve impulses to jump across a gap between two nerve cells in the brain called synapse.’
    • ‘In depressed people, too much serotonin is reabsorbed in the receiving neuron after crossing the synapse, the gap between neurons.’
    • ‘This process allows the vesicles to dock to that part of the membrane where the neurotransmitters are due to be released into the synapse (the active zone).’
    • ‘Much of this activity goes on at the synapse, or the regions where two neurons come into contact.’
    • ‘An electrical signal travels down one nerve cell, causing it to release the neurotransmitter into a small gap between cells called the synapse.’
    • ‘In general, the signal travels across the synapse from the axon of one cell to the dendrite of the next.’
    • ‘Yet a second problem was how this protein, once it was manufactured in the cell body of the neuron, could then find the one synapse among thousands that had called for it.’
    • ‘It's at a synapse that one nerve cell releases chemicals to signal an adjoining nerve cell.’
    • ‘The idea is the turn up the volume of neuronal signals that use acetylcholine as a transmitter molecule, by inhibiting the enzyme that would break it down and sweep it out of the synapse.’
    • ‘This results in a greater quantity of a particular neurotransmitter remaining in the synapse.’
    • ‘Various glutamate receptors have been shown to redistribute away from the synapse within as little as 5 minutes under certain stimuli.’
    • ‘There, electrical impulses propel vesicles into the cell wall to spray the neurotransmitter into the synapse.’
    • ‘The synapse is the probable arena where general anesthetics depress neuronal function.’

Origin

Late 19th century: from Greek sunapsis, from sun- ‘together’ + hapsis ‘joining’, from haptein ‘to join’.
