Gastrulation and folding occur in weeks 3 and 4, respectively. Choose the correct definitions of gastrulation and folding.

Gastrulation is the formation of the stomach in the embryo, including the formation of the gastric glands. Folding is used to refer to the ventral folding of the embryo disc

Gastrulation is the development of the mesoderm layer. Folding is the formation of the endoderm layer

Gastrulation is the formation of the trilaminar embryo (the ectoderm, endoderm and mesoderm). Folding consists of the ventral movement of the trilaminar embryo

Gastrulation incorporates the creation of the bilaminar embryo (the epiblast and hypoblast) and folding is used to refer to the ventral folding of the bilaminar embryo

What are the functions of the amniotic cavity? (Choose the option with all correct answers)

Protection from trauma, free movement, and it is the source for earliest blood vessels

Prevents foetus’ body parts from adhering together, protection from trauma, and maintains constant homeostatic temperature

Provides a buoyant environment, filled with mother’s urine, and maintains constant temperature

Allows the foetus to grow in a free area, provides a similar environment to the outside world, and allows for direct nutrient transport
