- How long does it take for the notochord to form?
- Mesoderm that is the origin for the epithelial lining of the urogenitial system (kidneys, gonads, bladders, adrenal glands, and associated connected ducts)
- Capillaries invade the ependymal layer of the ventricles to form:
- Notochordal mesoderm that migrate along the midline underneath the epiblast to form the early notochord will cause the adjacent cells to transform into:
- After gastrulation (up to formation of the gastrula) the embryo goes through ______ which starts the development of the nervous system
- _________ is induced by the adjacent notochord to form the nervous system of the embryo and the CNS + neuroglia.
- Cells that remain on the surface of the primitive streak will form the:
- Layer that is external to the mantle layer and formed from the peripheral growth of the nerve fibers from the mantle zone
- Epiblasts cells that migrate into the hypoblast and replace these cells will form the:
- Cells that migrate laterally between the epiblast and endoderm will become the:
- Forms the nucleus pulposis which contributes to the intervertebral discs that allow for cushioning between vertebral bone and facilitates the flexure of the vertebral column
- Layer formed from the neuroblasts that migrate from the matrix layer
- The ___________ is formed from the borders of where the neural plate had been.
- Single-layered blastula is eventually reorganized into the trilaminar structure called the
- Mesenchyme cells that move cranially from the primitive node form the:
- What is the earliest development between week 1-2?
- True or False: A good portion of the cells within the embryoblast contribute directly to the body
- During week 9, the embryo is consider a ________ until birth around week 39.
- Which week does the primitive streak form?
