Answer:
The milestones of prenatal development match to the trimester in the order: First trimester, Second trimester, Third trimester.
During each trimester of prenatal development, specific milestones occur as follows:
First Trimester
During the first trimester, the basic structures of the body are laid down. This includes the formation of limb buds, heart, eyes, and liver. These initial developments set the foundation for the growth and differentiation of the fetus.
Second Trimester
The second trimester continues the development of all organs and systems. At this stage, the fetus undergoes rapid growth, and the mother may start feeling fetal movements. This trimester is crucial for the fetus to further develop and mature.
Third Trimester
The third trimester witnesses the greatest growth of the fetus. During this period, the fetus gains significant weight, and its organs continue to mature. The third trimester culminates in the process of labor and delivery, marking the end of prenatal development.
Understanding the milestones of prenatal development and the corresponding trimesters is essential for monitoring the health and progress of both the mother and the fetus throughout pregnancy.
