What period begins from the time of conception until the delivery of the fetus?
The process of prenatal development occurs in three main stages. The first two weeks after conception are known as the germinal stage, the third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.
What is the fetal stage of prenatal development?
The last stage of prenatal development is the fetal stage, which lasts from two months after conception until birth. About one month into this stage, the sex organs of the fetus begin to form. The fetus quickly grows as bones and muscles form, and it begins to move inside the uterus.
What is germinal period?
The germinal period (about 14 days in length) lasts from conception to implantation of the zygote (fertilized egg) in the lining of the uterus. During this time, the organism begins cell division and growth. After the fourth doubling, differentiation of the cells begins to occur as well.
What happens in the germinal stage?
The germinal stage is the stage of development that occurs from conception until 2 weeks (implantation). Conception occurs when a sperm fertilizes an egg and forms a zygote. A zygote begins as a one-cell structure that is created when a sperm and egg merge.
Which trimester is the most critical for fetal development?
The first trimester is the most crucial to your baby’s development. During this period, your baby’s body structure and organ systems develop. Most miscarriages and birth defects occur during this period.
What are the 3 major stages of prenatal development?
Normal prenatal development lasts about 38 weeks and is divided into three stages: germinal, embryonic, and fetal. During these three stages of gestation, the original single-celled zygote develops into an embryo and then fetus [1, 2].
What is the most important stage of prenatal development?
Embryonic Period This stage lasts from implantation until about 8 weeks from the time of conception (or the 10th week of pregnancy). This is the most important time of prenatal development because the embryo is developing the foundations for a healthy baby.
What are the factors that affect prenatal development?
Prenatal risk factors include chronic maternal illness, certain maternal infections, toxin exposures and nutritional deficiencies. Risk factors in the perinatal period include pregnancy-related complications, prematurity and low birth weight, and infection exposure during pregnancy or at time of birth.
What is the perinatal period?
The perinatal period commences at 22 completed weeks (154 days) of gestation and ends seven completed days after birth. Perinatal and maternal health are closely linked. Perinatal mortality refers to the number of stillbirths and deaths in the first week of life (early neonatal mortality).
What is the difference between prenatal and perinatal?
Prenatal care is often defined as the time before birth. This is when a soon-to-be mother will come in for check-ups and care before the birth of their child. Perinatal care is the time before and after birth.
What is it called when a newborn dies?
