"Prenatal development includes the development of the embryo and of the fetus during a viviparous animal's gestation."
The physical and cognitive development that occurs before birth.
Conception: The process by which the sperm fertilizes the egg to form a zygote.
Embryonic development: The stages of development from conception to the end of the eighth week, during which the major organ systems are formed.
Fetal development: The stages of development from the ninth week until delivery, during which the fetus develops and matures.
Placenta: The organ that connects the developing fetus to the mother's uterus and facilitates the exchange of nutrients, oxygen, and waste.
Umbilical cord: The structure that connects the fetus to the placenta and provides essential nutrients and oxygen.
Teratogens: Substances or agents that can cause birth defects or developmental abnormalities, such as alcohol or smoking.
Genetic disorders: Inherited conditions that can affect prenatal development, such as cystic fibrosis or sickle cell anemia.
Prenatal care: Medical monitoring and interventions during pregnancy to ensure the health and well-being of the developing fetus and the mother.
Birth defects: Congenital abnormalities or malformation that occur in infants due to genetic or environmental factors.
Labor and delivery: The process by which the baby is born, including the stages of labor and different delivery methods like Cesarean section or vaginal delivery.
Neonatal care: Medical care and monitoring given to newborns during the first few weeks of life.
Postpartum depression: A mood disorder that affects new mothers and can cause sadness, anxiety, and thoughts of harming oneself or the baby.
Breastfeeding and formula feeding: Different methods of nourishing the baby after birth with their respective benefits and drawbacks.
Parenting and child development: The science and practice of raising healthy, well-adjusted children and fostering positive parent-child interactions.
Fertilization: The process of the sperm and egg merging together to form a zygote, marking the beginning of pregnancy.
Cleavage: The rapid cell division of the zygote into multiple cells called blastomeres.
Morula: The ball of cells formed after several rounds of cleavage.
Blastula: The hollow ball of cells that forms from the morula.
Gastrulation: The process by which the blastula develops into a three-layered structure (ectoderm, endoderm, and mesoderm) that will eventually give rise to all the organs and tissues of the body.
Neurulation: The process by which the neural tube - the precursor to the brain and spinal cord - forms from the ectoderm.
Organogenesis: The process by which organs and organ systems begin to develop, as cells differentiate into specialized tissues and organs.
Fetal period: The final and longest stage of prenatal development, when the developing organism is referred to as a fetus. During this time, organs mature and begin to function, and the fetus gains weight, grows, and develops more defined features.
"Prenatal development starts with fertilization, in the germinal stage of embryonic development."
"In human pregnancy, prenatal development is also called antenatal development."
"By the end of the tenth week of gestational age, the embryo has acquired its basic form and is referred to as a fetus."
"The fetal period is described both topically (by organ) and chronologically (by time) with major occurrences being listed by gestational age."
"Prenatal development starts with fertilization, in the germinal stage of embryonic development."
"By the end of the tenth week of gestational age, the embryo has acquired its basic form and is referred to as a fetus."
"The very early stages of embryonic development are the same in all mammals, but later stages of development, and the length of gestation varies."
