hey, does anyone have a nice list of what the three germ layers become? I have one, but I can't help thinking it's riddled with errors... or it's just worded weirdly. The way it seems, the mesoderm develops into pretty much everything and the ectoderm is like nothing. Doesn't seem right to me

Germ Layers

Ectoderm = Attract-o-derm* (epidermis, nervous system, eye lens, hair)
Mesoderm = Middle (Muscle, Cardiac & Skeletal Systems, blood, the heart, spleen)
Endoderm = Lining of Internal Organs (stomach, lungs, intestines, etc)

*consists of things that attract us to the opposite sex! You know, everyone wants the sexy skin/brains/eye lens!!!!

What about the actual organs stomach, lungs, intestines? Are they endoderm too?

yeah, I was kind of wondering this myself. That was where I was mainly unclear because the list I have doesn't say anything about the digestive/respiratory systems (just that the endoderm gives rise to their epithelial linings)

Organs are split between the endo and meso, althoug most come from the endo.
