Anyone have a good mnemonic or just a helpful way to remembering of which layers become what? I especially get endoderm and mesoderm confused.

Endoderm gives rise to the lining covering most of the organs. Example: Lining of respiratory organs and that of the digestive system.

Mesoderm, is anything that lays in between, including:
-Muscle
-Connective tissue
-Bone
******Notice that Muscle is attached to Bone via Connective tissue.
-Gonads
-Kidneys
-Circulatory system

Ectoderm gives rise to your Skin (Outter most layer), the Nervouse system (Your skin senses pressure, heat, etc), Hair (Hairy people have hair on their skin), Nails (Look at your finger tips, the skin eventually merges with your nails), and the retina (The retina converts visual input into electrical signals that are transferred to the Nervous system).

Just memorize whats in the ectoderm and endoderm, and everything else is mesoderm 😀

dont forget that the adrenal gland, the cortex is from mesoderm and the medulla is from etoderm. . . opposite than what you would normally think

and OF COURSE . . . enamal is from ectoderm

That's how i did it too 🙂! For endoderm, i remember by , "DR, Like playing the balls?" (Digestive, respiratory, liver, pancreas, thyroid, bladder linings.) I think "L" stood for livers.. some1 checked on that. I took the test 2 weeks ago.. already forgot half of everything XD
