HideShow resource information
neurotransmitters
chemicals that diffuse across the cleft to transmit a signal to the post synaptic neurone
1 of 8
cholinergic synapse
those that use acetylcholine as a transmission substance
2 of 8
synaptic knob
a swelling at the end of the pre-synaptic neurone
3 of 8
acetylcholineterase
an enzyme in the cleft that breaks down acetyl choline to ethanoic acid and choline
4 of 8
resting potential
the voltage across the neuron membrane when it is resting (-60mV compared to outside)
5 of 8
voltage gated channels
channels in the membrane that allows ions to pass,they have a gate mechanism and respond to change in voltage across the membrane
6 of 8
threshold potential
-50mV if the depolarization doesn't reach this level, no AP will be created
7 of 8
action potential
+40mV it is transmitted across the axon or dendron of the plasma membrane
