Hello, so let's answer now the problem.
00:03
So here in the problem, we are to complete the following sentences by putting the right words on the blank spaces.
00:13
These sentences are about the propagation of the action potential down a neuron.
00:19
So for the first sentence, the action potentials can be propagated slowly as in unmyrinated axons.
00:31
So if the axons are unmyrinated, then the action potential will be propagated slowly.
00:41
So our answer here is slowly.
00:44
Or if the action potentials will pass on the myelinated axons, then it can be propagated quickly.
00:57
So the next word here is we have quickly.
01:01
So take note that myelinated sheet provides insulation, hence ions inside axon membranes does not lost in action potential propagate faster than in myelinated fibers where some ions are lost.
01:19
So slowly and quickly.
01:22
So next let's proceed to the second sentence.
01:25
The jumping fashion of the saltatory conduction...
