epithelial linings
surface ectoderm
Epidermis
surface Ectoderm
Neurohypophysis
Neuroectoderm
Neurohypophysis
(what is it and what structure did it come from?)

(lack of migration of neural crest cells -> albinism)

Neural crest
(makes epi)

neural crest
(source of thyrocalcitonin; from 4th pharyngeal pouch)
Laryngeal cartilage
Neural Crest
Generally, what do neural crest cells become?
non-CNS neural cells (ganglia, schwann) and cells rel to nervous system that make NTs (chromaffin, etc)
also leptomeninges, odontocytes, and laryngeal cartilage (bone/cartilage from branchial arches)

mesoderm
spleen
mesoderm
adrenal cortex
mesoderm
gut tube epithelium - lungs, liver, pancreas
Endoderm
Thymus
endoderm (also starts as gut tube)
Thyroid, parathyroid
Endoderm
(these also derive from gut tube)
Nucleus propulsus (of intervertebral disk)
Notochord
What induces ectoderm to form neuroectoderm (neural plate)?
Notochord
Nephrons
Metanephric mesoderm
Exocrine pancreas
acinar cells and ducts form from endoderm surrounded by mesoderm
Endocrine pancreas
meosdermal cells aggregate to form pancreatic islet cells
