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 as self-directed learning exercise after completing the practical today.


  • Take the quiz and see what you know.
  • If you get some wrong, read the displayed information with the answer, and try working again through the Lecture and Practical.

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
  limb bud cartilage
  intervertebral disc
  skeletal muscle

6 The intraembryonic coelom finally forms

  pericardial, pleural and peritoneal cavity.
  single pericardial cavity and two pleural and two peritoneal cavities.
  neural tube lumen, gastrointestinal tract lumen and neural crest.
  the paired dorsal aortas running the embryo.

7 Which of the following statements about placodes is most correct.

  placodes form as patches of mesoderm only in the head region
  placodes are part of the neural crest that will contribute to sensory structures
  placodes contribute the upper and lower jaw structures of the head
  placodes are associated with sensory development, except for hearing.
  placodes are generally paired ectodermal regions.

8 The important human cardiogenic event commencing during week 5 is

  heart tube fusion
  heart looping
  heart septation
  heart valve development

9 Select the correct options below for maternal dietary components directly important for neural development

  lead
  vitamin B9

  endochondral ossification
  neither intramembranous or endochondral ossification
  intramembranous and not endochondral ossification
  both intramembranous and endochondral ossification
  chondroblast cell replacement of osteoblast cells
