Neurulation
This tubular structure derived from ectoderm will give rise to the central nervous system
Neural Tube
This type of mesoderm eventually splits into parietal and visceral layers
Lateral mesoderm
Which segmented structure that will give rise to the axial skeleton and associated muscle is derived from paraxial mesoderm?
The somites
This organ system, responsible for breaking down and absorbing nutrients, is derived from endoderm.
The gastrointestinal tract (digestive system)
This is the term for de novo synthesis of blood vessels from "blood islands."
Vasculogenesis
Taking this vitamin during early pregnancy helps prevent neural tube defects.
Folic acid
This type of mesoderm will give rise to the urogenital system
Intermediate mesoderm
What is used to determine the embryonic age during the first month of development?
The number of somites.
This part of the gut communicates with the yolk sac via the vitelline duct.
The midgut
This organ serves as the major site for hematopoietic stem cells in the fetus.
The liver
What levels of which molecule specify ectoderm to become neural crest cells?
Intermediate levels of BMP
This type of mesoderm, along with endoderm, form the wall of the gut tube.
Visceral mesoderm
What is the term for the oscillating pattern of Notch and Wnt expression that drives somite formation?
The segmentation clock.
The oropharyngeal membrane
This is the term for mesodermal cells that have differentiated into precursors for both endothelial and blood cells.
Hemangioblasts
High levels of this vitamin at the cranial end of the neural tube induces HOX genes that specify development of the brain stem.
Retinoic acid
These thin membranes responsible for secreting fluids around visceral organs are derived from parietal layer mesoderm.
Serous membranes
The part of the somite that differentiates into bone tissue.
The sclerotome
This membrane marks the end of the hindgut prior to the 7th week of develeopment
The cloacal membrane
This signaling molecule plays a central role in both angiogenesis and vasculogenesis.
VEGF
The lateral and medial movement of cells (i.e convergent extension) of cells during neurulation is driven by which signaling pathway?
PCP (Wnt) pathway
This type of mesoderm, along with ectoderm, line the intraembryonic cavity
Parietal layer mesoderm
The expression of Pax3 in a somite will lead to its differentiation into what type of tissue?
Dermis
This is the technical term for the primitive oral cavity
The stomodeum
This homeodomain transcription factor is the master regulator of lymphatic vessel development.
