When a single sperm cell from the male unites with an ovum (egg) in the female's fallopian tube in a process called fertilization
Term
Typical Prenatal Development
Definition
Begins with fertilization and ends with birth, takes between 266 and 280 days (38 to 40 weeks). It can be divided into three periods: germinal, embryonic, and fetal
Term
Germinal Period
Definition
The period of prenatal development that takes place in the first two weeks after conception. It includes the creation of the zygote, continued cell division, and the attachment of the zygote to the uterine wall
Term
Blastocyst
Definition
The inner layer of cells that develops during the germinal period. These cells later develop into the embryo.
Term
Embryonic Period
Definition
The period of prenatal development that occurs two to eight weeks after conception. During the embryonic period, the rate of cell differentiation intensifies, support systems for the cells form, and organs appear.
Term
Amnion
Definition
The life-support system that is a bag or envelope that contains a clear fluid in which the developing embryo floats
Term
Umbilical Cord
Definition
A life-support system containing two arteries and one vein that connects the baby to the placenta
Term
Placenta
Definition
A life-support system that consists of a disk-shaped group of tissues in which smal blood vessels from the mother and offspring intertwine.
Term
Fetal Period
Definition
Lasting about seven months, the prenatal period between two months after conception and birth in typical pregnancies.
Term
Teratogen
Definition
Any agent that causes a birth defect. The field of study that investigates the causes of birth defects is call teratology.

Greek origin "Tera" meaning Monster
Term
Genetic Susceptibility
Definition
The type of severity of abnormalities caused by a teratogen is linked to the genotype of the pregnant woman and the genotype of the embryo of fetus.
Term
Time of Exposure
Definition
Exposure to teratogens does more damage when it occurs at some points in development than at others.
Term
Psychoactive Drugs
Definition
Drugs that act on the nervous system to alter states of conciousness, modify perceptions, and change moods

Term
Birth Stage One
Definition
The longest of the three stages. Uterine contractions are 15 to 20 minutes apart at the beginning and last up to a minute. These contractions cause the woman's cervix to stretch and open. As this stage progresses, the contractions come closer together, appearing every two to five minutes. This stage lasts an average of 6 to 12 hours
Term
Birth Stage Two
Definition
This stage begins when the baby's head starts to move through the cervix and the birth canal. It terminates when the baby completely emerges from the mother's body. With each contraction, the mother bears down hard to push the baby out of her body. By the time the baby's head is out of the mother's body, the contractions come almost every minute and last for about a minute. This stage typically lasts approximately 45 minutes to an hour.
Term
Birth Stage Three; Afterbirth
Definition
The third state, at which time the placenta, unbilical cord, and other membranes are detached and expelled. This stage is the shortest of the three
Term
Doula

Natural Childbirth

Term
Prepared Childbirth
Definition
Developed by a French obstetrician, This childbirth strategy is similar to natural childbirth but includes a special breathing technique to control pushing in the final stages of labor and a more detailed anatomy and physiology course.
Term
Breech Position
Definition
The baby's position in the uterus that causes the buttocks to be the first part to emerge from the vagina.
Term
Cesarean Delivery
Definition
Surgical procedure in which the baby is removed from the mother's uterus through an incision made in her abdomen
Term
Apgar Scale
Definition
A widely used method of assessing the health of newborns at one and five minutes after birth. The Apghar Scale evaluates an infant's heart rate, respiratory effort, muscle tone, body color, and reflex irritability.
Term
Low Birth Weight Infants
Definition
An infant that weighs less than 5 1/2 pounds at birth.
Term
Preterm Infants
Definition
Those born before the completion of 37 weeks of gestation (the time between fertilization and birth)
Term
Kangaroo Care
Definition
Treatment for preterm infants that involves skin-to-skin contact
Term
