Centripetal spread = extremities to trunk
Centrifugal spread = trunk to extremities
Centripetal distribution = rash on trunk?
Centrifugal distribution = rash on extremities?

Is this real life?
Does the scientific community agree on this issue?
Are we all gonna make it?

Help

This concept from physics should help out, based on same idea. Yes, I think these are very set-in-stone concepts.

If you need a way to memorize it, these are latin derivitives.

Centri-petal = center seeking
centri-fugal = center fleeing

I know RMSF is centripetal

What is centrifugal? Epidemic typhus (prowazaki) I think, but what else?

I think the vast majority are centrifugal. Centripetal is the oddball

centripetal is in kawasaki.

Ok, but is it different when they say centrifugal distribution right? That just means it's in the extremities, then. Center fleeing?

Pour a bucket on honey on your head and then spin in circles. If you still don't understand, wikipedia.org. lmao.

I...I dont...WHAT IS THIS

These are two subjects that should never collide. It's like trying to stick two protons together. IT'S UNNATURAL.

Is this from an actual question? This seems like mcat material.

They wont say centripetal or centrifugal they will describe how rash is being spread e.g started on wrist, ankles then spreaded to trunk.It'd better be off memorising how rashes are spread, elements of the rashes, check out google images for every dermatologic condition which in FA(e.g shagreen patch, angifibroma, etc.)

Oh my bad, I just saw the rash now. Initially, I took a cursory glance and saw the word centrifugal and then turned away lol.

You can tell that I was never a fan of physics.

They could ask it with those terms, it is a commonly used medical term to describe how the rash spreads. They would try to clue you in with other stuff too, but they are known for using alternative medical terms to throw you off in some very basic concepts. Like this other time, I was checking some NBME discussion, and there were a good deal of people upset and frustrated on a question because it said "abdominal viscus", referring to the abdominal organs. lol

In the end, you are better off learning the high yield concepts as you said, BUT they COULD put this in, and all your high yield cramming goes out the window.
