explain this...

[IALuder]

I dont understand why drinking something can/will make you blind. Can someone explain this?

[sicones]

Did you drink isopropyl alcohol???

toxins tend to act on nerve tissue

[IALuder]

how do they know to ruin the nerves.

[Mischief]

they don't know to, they just do.

[pdiggitydogg]

its not that they know, its just the tissue type that is susceptible through various actions
IE) Methanol metabolizes to form an acid that is a direct retinal toxin = blindness/vision loss
Other toxins act as a protein receptor plug on cell surfaces(venoms act the same way) - when the receptor is plugged, cells can either die from lack of nutrients (depending on the receptor) or just cease function in their design

You know those antidepressant ads, that show a gap between 2 different nerve cells (this is called a gap junction, btw). Think of a toxin molecule being inserted into the recepor protein of one cell, meaning that it cannot receive information from its partner. No data transfer = inactivity = possible cell atrophy

so i see. :|
