Prenatal development encompasses the period of growth and maturation that occurs in an unborn child before birth. This process begins at conception and continues until the moment of birth, typically lasting around 40 weeks. During this time, the fetus undergoes rapid physical, neurological, and emotional development, forming organs, tissues, and structures essential for life outside the womb. Prenatal development is a critical stage in human growth and is influenced by various factors such as genetics, nutrition, environment, and maternal health. Researchers in this field study how these factors impact fetal development and how disruptions or abnormalities during this period may lead to long-term health outcomes for the individual. Understanding prenatal development is important for promoting healthy pregnancies, preventing birth defects, and improving maternal and infant health.
