Development

What does the prosencephalon primary brain vesicle develop into?

Thalamus, epithalamus, hypothalaus, subthalamus, cerebral cortex and basal ganglia +lateral and third ventricle (via diencephalon and telecephalon)

When does the embryo become trilaminar?

three weeks. (mesoderm is now on the scene)

what does the dermatome form?

dermis and subcutaneous tissue (D=Dermis)

What does the mesoderm form?

dermis, skeleton, muscle, blood and blood vessels, urogenital system

Distinguish neural epithelium from neural crest?

neuroepithelial cells are what form ependymal cells, glioblasts, neuroblasts, and microglia. neural crest is the part of the ectoderm that forms PNS and non-neural structures nerby

What does the endoderm form?

the digestive and respiratory systems

Neural crest derivatives

ANS, DRG, cranial nerves, celiac ganglion, melanocytes, chromaffin cells of adrenal medulla, enterochromaffin cells, C cells of thyroid, schwann cells, pia and arachnoid, bones of the skull

What is the origin of gray matter? What is the origin of white matter?

Grey matter is from the mantle of the neural tube. White matter is from the marginal layer of the neural tube.

What does Neuroectoderm/Neuroepithelium form? How about Neural Crest?

Neuroectoderm - CNS and brain. Neural Crest - PNS and non-neural structures nearby.

What generally does ectoderm form?

The Epidermis, skin glands, hair, lens, iris, cornea, and inner ear. (the neuroectoderm arises from a specialized region of the embryonic ectoderm and forms the neural tube)

What does the sclerotome form?

axial skeleton and cartilage (S=Skeleton)

What are somites?

blocks of mesodermal tissue along axis of embryo

What does the rhombencephalon primary brain vesicle develop into?

medulla, pons, cerebellum + forth ventricle (via myelencephalon and metencephalon)

What does the mesencephalon primary brain vesicle develop into?

midbrain + aqueduct (via mesencephalon)

what does the myotome form?

skeletal muscles (M=myotome)
