Quick and informative, much much easier to remember this with the visuals rather than just reading

[jeffreycheung]

It makes things sooo easy to be memorised!!!

Trigone of the bladder is derived from the mesoderm(intermediate mesoderm) and rest of the bladder Is from the endoderm

[benof]

Thank you so much for this video! I was having so much trouble keeping track of all the different organs the germ layers differentiated into but this video helped so much!

[chocolatecupcake]

bladder is derived from the endoderm, not mesoderm

[NimbusFilmsOfficial]

Thank god for the comment section, the bladder is endoderm derived. This video tripped me up so much studying for the MCAT, almost missed a question on the exam. ANNOTATE OR REUPLOAD. Disgraceful, Khan Academy.

Great explanation, very helpful for people with short span attention like me. Thank you so much!

[venkatikendre]

What I have learnt :
Origin of different body organs
Endodermal in orgin :
Oesophagus, stomach, intestines, liver, pancreas, lungs
Mesodermal in origin :
Inner skin layers, heart, muscles, bones, kidneys, urinary bladder, reproductive organs - testes, ovaries .
Ectodermal :
Organs in the nervous system, outer layers of skin, hairs, sweat glands etc.
Thanks a lot sir !

[mallickabag]

Thank you. It helps me in understanding it.

[adhamhamadneh]

thanks a lot, but the mesoderm doesn't give rise to the bladder . 
It's an exception

[doodlezzable]

Bladder is derived from endoderm. Isn't it?

[bhoopsingh]

Thank-you very-very much
For making this basic-concept video|
Thank-you|

[anajovana]

as far as i know bones derive from the ectoderm, too. only vertebras and ribs are from the mesodermal somites the skleroderm. (source is prometheus)

[salehalatar]

Which one of these layer form first? Or does they form exactly the same time? or does one of them form another one ?

[tfoprincess]

Would be funny if that drawing became real like what happened in spongebob

[jeetendrakhushlani]

Isn't urinary bladder endodermal in origin ???

[bezmitiptip]

can you make your videos more advanced which will make it appealable for med students as well you can easily say that wouldnt come in mcat and give time lines in explanation of video which covers med side and mcat students can easily skip these parts of it. i think lots of people would consult you if you did like that thanks

[reznof]

Why are they called germ layers?
Arent germ cells responsible for gametes?

[mattm]

Why the f do we need to know this shit. This is not ever going to help me in any way. Great video though :).

[drashabahmed]

these are not that simplified actually.. lots of missing information
