What is the term for the gap between the presynaptic and postsynaptic membranes?
|
Synapses allow transmission of nerve impulses in only one direction - from neurones to neurones.
|
Where are neurotransmitter receptors located in the synapse?
in the synaptic cleft
on synaptic vesicles
on the postsynaptic membrane
on the presynaptic membrane
|
Which structural component of the synapse contains neurotransmitters before an action potential arrives in the presynaptic neurone?
synaptic cleft
presynaptic membrane
synaptic vesicles
postsynaptic membrane
|
Which structure of the synapse contains organelles involved in neurotransmitter production?
synaptic knob
synaptic cleft
synaptic vesicles
neurotransmitter receptors
|
Synaptic transmission can be described as:
unidirectional
multidirectional
omnidirectional
bidirectional
|
Which statement best describes the effect of summation at synapses?
increases likelihood of postsynaptic firing
releases inhibitory neurotransmitters
makes postsynaptic firing less likely
prevents repeated presynaptic firing
|
Which statement about synaptic transmission is true?
can initiate multiple postsynaptic impulses
requires repeated firing to be effective
designed to allow bidirectional transmission
prevented by excitatory inputs
|
What is the term for the strengthening of postsynaptic response when multiple presynaptic neurones converge on a single postsynaptic neurone?
|
