- Gestation is the carrying of an embryo or fetus inside female viviparous animals. It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time (multiple gestations). The time interval of a gestation is called the gestation period. In human obstetrics, gestational age refers to the embryonic or fetal age plus two weeks. This is approximately the duration since the woman's last menstrual period (LMP) began. 1 Mammals.

Prenatal development For other species, see prenatal development (biology). For maternal changes in the prenatal period, see Maternal physiological changes in pregnancy. Prenatal or antenatal development is the process in which a human embryo and later fetus (or foetus) develops during pregnancy, from fertilization until birth. Often, the terms fetal development, or embryology are used in a similar sense.

Gestational age Gestational age (or menstrual age) is a measure of the age of a pregnancy where the origin is the woman's last normal menstrual period (LMP), or the corresponding age as estimated by other methods.he gestational age for fetal viability ranges from 16 weeks in Norway, to 20 weeks in the US and Australia, 24 weeks in the UK, and 26 weeks in Italy and Spain. Gestational age (as well as fertilization age) is sometimes used postnatally (after birth) to estimate various risk factors.

Preterm birth Preterm birth, also known as premature birth, is the birth of a baby at less than 37 weeks gestational age. These babies are known as preemies or premmies. Symptoms of preterm labor include uterine contractions which occur more often than every ten minutes or the leaking of fluid from the vagina.

What is the Gestation Period? For example, the average human gestation period is 38 weeks. Gestation may normally last anywhere from 37 to 42 weeks, however, and be considered well within the healthy range. Any child born before 37 weeks is considered preterm, and this can be accompanied by any number of health risks.

Preterm birth In humans the usual definition of preterm birth is birth before a gestational age of 37 complete weeks. In the normal human fetus, several organ systems mature between 34 and 37 weeks, and the fetus reaches adequate maturity by the end of this period.reterm birth, also known as premature birth, is the birth of a baby at less than 37 weeks gestational age.

How Thermochromic Ink Works Well, sometimes our possessions and paints really can change color, thanks in part to thermochromic ink technology. Thermochromic inks take advantage of thermochromism, which refers to materials that change their hues in response to temperature fluctuations.hermochromic inks first hit the mainstream in the 1970s, appearing in one of that era's lasting icons -- the mood ring, which supposedly used the wearer's body heat as a sign of his or her emotional state.

Prenatal development Prenatal development, also called antenatal development, in humans, the process encompassing the period from the formation of an embryo, through the development of a fetus, to birth (or parturition). 1  The human body, like that of most animals, develops from a single cell produced by the union of a male and a female gamete (or sex cell).

Pregnancy Pregnancy is the period of time when a fetus develops inside a woman's uterus and ends with the birth of the infant. There are a variety of clinical laboratory tests typically used prior to and throughout pregnancies. The tests provide useful information from the time pregnancy is first considered through the initial days of the newborn's life.

- Definition. A premature baby is one born before 37 weeks of gestation time. If a woman goes into labor before 37 weeks, it is referred to as preterm labor. In a typical pregnancy, delivery between 37 and 42 weeks is considered a full term, and anything after 42 weeks gestation is a post-term pregnancy.f a woman goes into labor before 37 weeks, it is referred to as preterm labor.

Childbirth This article is about birth in humans. For birth in other mammals, see birth. Childbirth, also known as labour and delivery, is the ending of a pregnancy by one or more babies leaving a woman's uterus. In 2015 there were about 135 million births globally. About 15 million were born before 37 weeks of gestation, while between 3 and 12% were born after 42 weeks. In the developed world most deliveries occur in hospital, while in the developing world most births take place at home with the support of a traditional birth attendant.

Pregnancy Pregnancy, also known as gravidity or gestation, is the time during which one or more offspring develops inside a woman. A multiple pregnancy involves more than one offspring, such as with twins.Pregnancy can occur by sexual intercourse or assisted reproductive technology. It usually lasts around 40 weeks from the last menstrual period (LMP) and ends in childbirth. This is just over 9 lunar months, where each month is about 29½ days. multiple pregnancy involves more than one offspring, such as with twins.

What to expect during pregnancy Pregnancy, or gestation, is a period of approximately 9 months when a woman carries an embryo or fetus in her uterus. The first sign of pregnancy is normally missed menstruation, but there are other signs too. If a woman has the other signs but does not miss a period, she is not pregnant. Contents of this article:

Gestational age Gestation is the period of time between conception and birth. During this time, the baby grows and develops inside the mother's womb. Gestational age is the common term used during pregnancy to describe how far along the pregnancy is. It is measured in weeks, from the first day of the woman's last menstrual cycle to the current date. A normal pregnancy can range from 38 to 42 weeks. Infants born before 37 weeks are considered premature.

- Prenatal or antenatal development is the process in which a human embryo or fetus (or foetus) gestates during pregnancy, from fertilization until birth. Often, the terms fetal development, foetal development, or embryology are used in a similar sense.ince the precursors of all the major organs are created by this time, the fetal period is described both by organ and by a list of changes by weeks of gestational age. Because the precursors of the organs are now formed, the fetus is not as sensitive to damage from environmental exposure as the embryo was.
