释义

Definition of synapse in English:

synapse

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

    Example sentencesExamples
    • It codes for the protein in neurons that recycles secreted serotonin from the synapse.
    • At the end of the trunk is a synapse or connection with other items, usually roots of other neurons.
    • When the spike reaches the synaptic terminals it causes neurotransmitters to be released into the synapse where they then flow to post-synaptic neurons.
    • Various glutamate receptors have been shown to redistribute away from the synapse within as little as 5 minutes under certain stimuli.
    • 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.
    • 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.
    • 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).
    • It's at a synapse that one nerve cell releases chemicals to signal an adjoining nerve cell.
    • In depressed people, too much serotonin is reabsorbed in the receiving neuron after crossing the synapse, the gap between neurons.
    • 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.
    • Much of this activity goes on at the synapse, or the regions where two neurons come into contact.
    • 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.
    • The synapse is the probable arena where general anesthetics depress neuronal function.
    • 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.
    • There, electrical impulses propel vesicles into the cell wall to spray the neurotransmitter into the synapse.
    • He found that learning occurs at the synapse (the junction between two neurons) by several means.
    • An electrical signal travels down one nerve cell, causing it to release the neurotransmitter into a small gap between cells called 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.
    • In general, the signal travels across the synapse from the axon of one cell to the dendrite of the next.
    Synonyms
    join, joint, intersection, link, bond, weld, seam, coupling, connection, union, juncture

Origin

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