Open Ended

Why is it important to understand the stages of prenatal development, particularly from the third to the eighth week of embryonic development?

Multiple Choice

Which of the following biological processes occurs during the third week of prenatal human development?

• Gastrulation

• Fertilization

• Organogenesis

Open Ended

Describe the significance of the embryonic period from the 3rd to the 8th week of development.

Multiple Select

Which of the following are components of the germ layers shown in the diagram?

• Ectodermo embrionario

• Mesodermo lateral

• Placa neural

• Amnios

Fill in the Blanks

The appearance of the notochord and prechordal mesoderm induces the ectoderm to thicken and form the

Open Ended

Explain the significance of the communication between the neural tube and the amniotic cavity during neurulation.

Fill in the Blanks

gives rise to the neural tube.

Multiple Choice

Which germ layer gives rise to the neural tube during embryonic development?

• Ectoderm

• Mesoderm
