Quick video axial filament. So I want to cover the axial filament so the axial filament is a special type of flagella as you can see here it's called an endo flagella let's go ahead and get just to move a little bit closer here so the axial filament is a flagella that's attached on one end and then coils around the Organism so here's the key so like other flagellates you it's used for movement but um it's only going to be found in your spiral beat organisms so the two key examples I'd want you to know would be treponema pallidum which is the causative agent of syphilis and borrelia burgdorferi the causative agent of Lyme disease so what's cool about these as you can see with this with arrow is that a counterclockwise um arrow here the actual filament when they contract that actually causes the cells to spin so I think about like a drill bit so this Organism can basically drill itself forward or drill itself backwards by how this axial filament is contracting so here's an actual picture of a treponema Palladium the spiral keta so as you can see this really cool Corkscrew fashion but like a Corkscrew they literally can drill themselves forward going backwards as they're moving towards food or away from it whatever so right back to that main picture here so this is the axial filament the special kind of flagella used for movement only found in your spiral key keat organisms OK have a wonderful day be blessed.
