Fetal gestational age comparison table – an essential tool for understanding fetal development trajectory
During pregnancy, expectant mothers often pay attention to the development status of the fetus, especially wanting to know the more obvious changes and development of the fetus in which periods. The fetal gestational age comparison table came into being to meet this need. This article will introduce the relevant knowledge of the fetal gestational age chart in detail from four aspects: gestational age chart, fetal growth and development, fetal facial features in utero development and fetal movement.
Pregnancy week comparison table
The pregnancy week comparison table, as the name suggests, is a table that records the development of the fetus during pregnancy and displays it based on the time dimension. In this table, parameters such as the corresponding time for each gestational week from the first day of pregnancy to the expected date of delivery, the average length, average weight of the fetus, and the completion of major organs are generally displayed. Among them, the main function of the gestational age comparison table is to understand various changes in the fetus as the gestational age increases by comparing parameters at different gestational ages.
Fetal growth and development
As the gestational age increases, the growth and development of the fetus will progress by leaps and bounds. In the first trimester (1-4 weeks), the fetus continues to increase its cell number mainly through cell division. In the second trimester (5-28 weeks), as the development of various fetal systems begins to gradually improve, its growth rate will rapidly accelerate, and some organs will also begin to exhibit significant functional characteristics. In the third trimester of pregnancy (29-40 weeks), although the growth rate of the fetus will slow down, there is still room for growth in the improvement of its organs and functions.
Intrauterine development of fetal facial features
The intrauterine development of the fetus\’ facial features is also an issue that expectant mothers are more concerned about. In the first 3 months of pregnancy, the fetus\’s facial features will gradually form, but the functions of each organ are not yet fully mature. Among them, the head and brain are the control centers of fetal life activities, so they begin to grow rapidly in the early stages of pregnancy. Later, as the nerves that control limb movement gradually form and improve, the fetus will also begin to be able to move with the help of the pregnant mother\’s abdominal wall surface. By the third trimester of pregnancy, the fetus\’s facial features are basically fully developed, but it will take several months after birth to fully mature.
Fetal movement
Fetal movement is a very important part of fetal development and is also an issue of great concern to expectant mothers during pregnancy. During pregnancy, the fetus will move in a variety of ways, such as rolling, kicking, making fists with fingers, etc. The intensity and frequency of these movements will gradually increase with the development of the fetus, especially in the third trimester of pregnancy. As the placenta ages and the intrauterine space becomes increasingly tight, the frequency of fetal movements will increase and decrease accordingly.
Summary
The fetal gestational age chart is an essential tool for understanding the fetal development trajectory. The gestational age comparison table mainly understands the growth and development of the fetus by comparing the changes in various parameters of the fetus at different gestational ages. Specifically, when it comes to the intrauterine development of the fetus\’s facial features, the appearance and formation of their functions are carried out in stages; And fetal movement is aImportant signs that show the health and activity level of the fetus. Based on the above, understanding the fetal gestational age chart can enable expectant mothers to better understand the various changes that occur with their cute babies as the gestational age changes.
