Members do not see this ad.

Pancreas = ?
Kidney = mesoderm, right?
Cerebellum = ?
Duodenum = medoderm?
heart = mesoderm for sure

help me with this..........

 

[dantheman2007]

pancreas- endo
you're correct on kidney
duodenum - endo
cerebellum - (brain...neural tube) - ectoderm
Best,
Dan

How can you tell dude?
Ecto = nervous system
Meso = circulatory system
Endo = digestive system

so how do I put all of those into these categories

can u please make some other hard examples of these 3 layers

 

[Lonely Sol]

Since you want some hard ones, here ya go:

Adrenal medulla
Adrenal Cortex
Hypothalamas

 

[Toothguy80]

hypothal is ectoderm
but I have no idea on the rest
tell me what they are please?

 

[dantheman2007]

adrenal medulla - neural crest - ecto

 

[Toothguy80]

Why, because they happen in the brain?

how do you link them to the nervous system?

Here is another one
Pituitary

Ectoderm.
(More specifically Posterior is from nerural ectoderm, anterior is from oral ectoderm - the middle lobe I have no idea)

 

[dentistin2011]

adrenal cortex = mesoderm
adrenal medulla = ectoderm

 

[Toothguy80]

Why are gonads mesoderm? How are they in the circulatory system?

They are way down in the body so I thought they would be endoderm

 

[AaBbZz]

Gonads are not part of the circulatoruy system. the way I remember most of them is

Ectoderm= skin, teeth, lens of eye, nervous system

Endoderm= Tracts and Lining (PLT= pancreas, liver and thyroid) and bladder
- I use PLT because its also the order pathway for respiration
(Phrynax,Larynx and Trachea)

Mesoderm= everything else

Nice, thanks
