Bi12 Nervous System Part 3

Totally Hollywood: glamourous without a lot of substance ;)
-love the sizzle and thunder


More substance here: Sodium's travels during and after an impulse, well done lads
-more sizzle

Bi12 Nervous System Part 2

What happens at the gap? -> Actual fusion of synaptic vesicles with the pre-synaptic membrane; movement of neurotransmitters, to receptors on the other side


after the action potential or electrical signal has traveled down the neuron it needs to get sodium back to the outside against the gradient and potassium inside, also against its concentration gradient
-this requires energy

Bi12 Nervous System Part 1 - Action Potentials

a little confusing at first but good close up of action at the synapse; david suzuki


how sodium (Na+) channels and potassium (K+) channels work together to cause the impulse or action potential to travel like a wave down the axon
