Here are a few simple questions that relate to your BGD practical, this page is not a part of today's Practical class. You should try in your own time after completing the Practical today.Take the quiz and see what you know, if you get some wrong, try working through through the 2010 BGD Practical - Implantation to 8 Weeks.

Take the Quiz

  

1 Which of the following sequences of embryonic disc mesoderm is most correct:

lateral to medial: extraembryonic - lateral plate - intermediate - paraxial
lateral to medial: lateral plate - paraxial - intermediate - axial
medial to lateral: notochord - somites - intermediate - lateral plate
medial to lateral: paraxial - axial - intermediate - cardiac

2 During embryonic disc folding in week 3 only the ectoderm layer folds ventrally left, right and above and below the notochord.

true
false

3 Somites form regularly at the level of the body in the direction

rostrocaudally
caudorostrally

4 The intraembryonic coelom is a horse-shoe shaped cavity that develops in the lateral plate mesoderm from a series of smaller cavities fusing. Which of the following descriptions best describes the structure that then forms in this region.

somatic mesoderm close to ectoderm, the intraembryonic coelom and the splanchnic mesoderm closest to the endoderm.
somitic mesoderm close to ectoderm, the intraembryonic coelom and the splanchnic mesoderm closest to the endoderm.
somatic mesoderm close to endoderm, the intraembryonic coelom and the splanchnic mesoderm closest to the ectoderm.
somitic mesoderm close to endoderm, the intraembryonic coelom and the splanchnic mesoderm closest to the ectoderm.
intermediate mesoderm medially close to somites and laterally close to the intraembryonic coelom.
none of the above.

5 Select the correct options below for the structures formed by sclerotome

vertebra
dermis
