Which of the following sequences accurately reflects the order of the stages of prenatal development mA-A-Fetal, germinal and embryonic
B-Fetal, embryonic and germinal
C-Germinal, embryonic and fetal
D- Germinal, fetal and embryonic
C- Germinal, embryonic and fetal
The correct sequence of the stages of prenatal development is:
C- Germinal, embryonic, and fetal.
To determine the correct answer, we need to understand the correct order of the stages of prenatal development.
The three main stages of prenatal development are the germinal stage, the embryonic stage, and the fetal stage.
1. Germinal Stage: This is the first stage of prenatal development and lasts approximately the first two weeks after conception. During this stage, the fertilized egg (zygote) undergoes rapid cell division and begins to form the blastocyst, which eventually implants into the uterine lining.
2. Embryonic Stage: This stage begins around week 3 and extends until week 8 after conception. During this stage, the embryo continues to develop, and all major organs and body structures begin to form. This is a critical period for organ development, and the embryo is particularly susceptible to external influences.
3. Fetal Stage: The fetal stage begins around week 9 and lasts until birth. During this stage, the developing organism is called a fetus. The primary focus of this stage is the growth and maturation of existing structures rather than the formation of new ones. The fetus continues to grow in size and weight as organs, systems, and tissues develop and become functional.
Based on this information, the correct order of the stages of prenatal development is: Germinal, Embryonic, Fetal.
Looking at the given options, option C: Germinal, embryonic, and fetal accurately reflects the correct order of the stages of prenatal development.
Thus, the correct answer is C - Germinal, embryonic, and fetal.
