structure of the synapse Flashcards
where does the impulse travel from and to
presynaptic neurone to postsynaptic neurone
what is the end of the presynsaptic neurone called
synaptic knob
what does the presynaptic neuron have lots of
mitochondria
why does the presynaptic neurone have lots of mitochondria
to provide energy for synaptic transmission
what does the neurotransmiter exhist in the pre synaptic neurone
stnaptic vesciles
what absorbs excess neurotransmitters
reuptake pump
where is the reuptake pump located
presynaptic neurone
what is the auto receptor
helps control the amount of neurotransmitter released
where is the auto receptor located
presynaptic neurone
what else is present on the presynaptic neurone
calcium channel
what is the gap between the presynaptic neurone and postsynaptic neurone called
synaptic cleft
what is located on the post synaptic neurone
receptor protiens
what do the receptor protiens do
bind to neurotransmitters and stimulate action potential
define the synapse
the point where the axon of one neurone ‘connects’ with the dendrite of another
what is the direction of the nerve impulse
unidrectional
