The are bristle or hair like structures. Their function differs based on the organism concerned . In zoology its moslty in invertebrates , in entomology its reffered to as chaete. The link above would give an overview of what is referred to a setae based on what organism ur concerned with.

In annelids. It describes them both as hair/bristle like structures =/

That should make it more clear . Its the same thing . Both seta and cheta or chaete means bristles. I think the term can be used interchangeably . Just check this link:- http://en.wikipedia.org/wiki/Polychaete It about polychaetes a class of annelid worms. These are extracts form the passage:- Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called *chaetae, which are made of chitin. Indeed, polychaetes are sometimes referred to as bristle worms. Bundles of bristles, called *setae, project from the parapodia. http://en.wikipedia.org/wiki/File:Polychaeta_anatomy_en.svg Thats a cross section the terms have been used interchangebly.

OpenStudy (anonymous):

The definition of chaetae:- A *chaeta or *cheta (see spelling differences) is a chitinous bristle or *seta found on an insect, arthropod or annelid worms such as the earthworm, although the term is also frequently used to describe similar structures in other invertebrates.

Hope it helps.

OpenStudy (anonymous):

setae is latin for bristle and chaetae is greek for bristle. so basically it means the same thing.

You really work hard :) Much appreciated! Thank you so much!

There are structural level differences between the cheate of annelids and setate of arthropods . But between annelids they are used interchangeably.
