Practical 6: Week 3 | Week 4 | Week 5 | Week 6 | Week 7 | Week 8


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 practical.

Take the Quiz

   Syntax error

1 During week 2 the blastocyst implants and the outer cell layer in that week becomes:

  decidual cells and hypoblast cell layer
  cytotrophobasts and syncitiotrophoblasts
  chorion and amniotic membranes
  the embryoblast and inner cell mass

2 The human placenta is derived from only fetal cells.

  true
  false

3 The embryo umbilicus contains is

rostrocaudally
caudorostrally

4 Which of the following statements concerning the amniotic membrane is incorrect.

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

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 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
iodine
chlorine
vitamin B3

10 Which limbs are sensitive to teratogenic damage first

upper limbs
lower limbs

11 The bones of the adult skull form only by the process

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