[shahalam]

i've never really run across these terms before...is there an easy way to remember these terms and what they mean and are there any other words like them that describe a reaction that could be important?

in vitro is just experiments in test tubes, and vivo is in living organisms........how hard is that? lol

I remember them because "vivo" means "alive" in Spanish. So in vivo experiments are done in living creatures.

like in in vitro fertilization, the embryo's created in a test tube

"in vitro" is a Latin word that literally mean "in glass" - this refers to experiments conducted in non-living media such as glasses, petri dishes and test-tubes. "in vitro" is the equivalent of/otherwise called "ex-vivo"

"in vivo", on the other hand, also Latin, means "in life" - refering to studies conducted within living organisms.

It may help to think of these terms in reference to living organisms with:
"in vivo" meaning "INternal to a living organism"
"ex vivo" (aka "in vitro") meaning "EXternal to a living organism"

Yeah there are other such words too. Like: in situ (in the natural environment), ex situ.

 

[Samus]

and in silico is a newer one, meaning done via computer model

Yeah there are other such words too. Like: in situ (in the natural environment), ex situ.

just remember in-vitro and you'll automatically remember invivo.
