Developmental Horizons During Fetal Life Event

developmental horizons of human fetus
In this brief post, we will discuss some development horizons during fetal life events. These developmental horizons help us to determine how optimum the intra-uterine growth and development of the fetus is in relation to its age. Length of the fetus and uterine fundus height determine the adequacy of the physical growth of the baby, but there are few other parameters which help us to have an idea of neuronal growth and development of the baby. These parameters include; an appearance of taste buds, initiation of swallowing and respiratory movements, Sucking movements, Response to the sound, Sensitivity of eyes to light.
So the physical growth of the baby should lie in parallel to the neuronal growth of the fetus. For example, the fetus starts swallowing movements as early as 10 weeks of age. So if fetal length corresponds to the age of 10 weeks then swallowing movements should also be present at that time. Similarly, other parameters are listed below;

The appearance of taste buds     7 weeks
Initiation of swallowing movements     10 weeks
Initiation of respiratory movements     14-16 weeks
Initiation of Sucking movements     24 weeks
Response to some sounds     24-26
Eyes become sensitive to light     28
