So demyelination in the peripheral
nervous system is mostly gonna affect motor axons,
cuz they conduct, they transfer information the fastest.
So these are gonna have a lot of motor symptoms.
But once we go to the central nervous system, there are axons all over,
there are myelinated axons all over that do all manner of things.
And the symptoms that a person gets with
multiple sclerosis will entirely depend on which axons are affected.
Now there are axonal groups that are more typically affected than others
in multiple sclerosis, but there's no group that's always affected, and
there's no group that's immune from the effects of multiple sclerosis.
So the effects of multiple sclerosis are at a basic level
to disrupt the neural code.
But the actual symptoms that will result from that disruption
are going to be individual across the group.
Okay, so in the next module what we're gonna do is we're gonna clarify this
difference between the central nervous system and the peripheral nervous system.
