Neural Synapse

i love youtube. and i hate ap biology  =D

thank you

haha

Thanks! this really helped me on my biologytest!

The action potential does NOT simply pass to the next cell as the video suggests. Instead, the action potential in the presynaptic terminal causes the neurotransmitter to be released (as shown), which may cause an EPSP in the postsynaptic dendrite. The EPSP passively moves through the dendrites and soma to the axon hillock and, if it is strong enough to bring the membrane potential there to threshold.

True, but it depends on what level you want to comprehend the process. For basic understanding, this is enough. Really helped me, anyway. I read it in my text book, but I just had to see it.

If im not mistaken dosen't an action potential cause voltage gated Ca2+ channels to open allowing Ca2+ into the cell which in turn causes the neurotransmitters to exocytose into the synaptic cleft.

You're not mistaken, and this explanation is very vague.

lauren = neural.. jsut swap the letters around!

oh sure, makes perfect sense to me -- i just need to watch this about 68 more times.
