Members don't see this ad.

where would simple columnar tissue be found?

 

[hellocubed]

Isn't all columnar tissue just found in the epithelium?

 

[chiddler]

look what i found!

GI is primarily simple columnar.

I don't think you have to know that kind of stuff though..

 

[chiddler]

oh

nvm then.

Yea, seriously--there is no indication on the AAMC list that we need to know that. But they have tested it. Just like voles..Ridiculous

So according to Wiki:

simple squamous is found in lining where passive diffusion occurs (so like capillaries?)

simple cuboidal--secretory, absorptive or excretory

simple columnar--super secretory, absorptive or excretory like cilia & microvilli--apparently structures designed primarily for those functions

pseudostratified epithelia= respiratory epithelium.

Stratified squamous is for physical protection (esophagus, skin, etc).

nah i think medpr is right. i'm surprised that it's not, though, as this is also stuff i learned in high school bio but not in mcat studying.

surely the prep books would have mentioned it since it is not a very long or complicated topic.

I have no idea what you're talking about. 🙁 It's cool that the writing is gone, now if BS could go away too...
