| A) | Measure that provides a comprehensive analysis of the newborn's neurological and stress responses.
|
| B) | An outer layer of cells that develops in the germinal period. These cells will become part of the placenta.
|
| C) | From the Greek word "tera," meaning "monster." Any agent that causes a birth defect. The field of study that investigates the causes of birth defects is called teratology.
|
| D) | An infant that weighs less than 5 ½ pounds at birth.
|
| E) | Infants whose birth weight is below normal for the length of gestation.
|
| F) | 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.
|
| G) | Contains two arteries and one vein; it connects the baby to the placenta.
|
| H) | A caregiver who provides continuous physical, emotional, and educational support for the mother before, during, and after childbirth.
|
| I) | Infants born three weeks or more before gestation is completed.
|
| J) | A widely used method to assess the health of newborns at one and five minutes after birth. The Apgar Scale evaluates an infant's heart rate, respiratory effort, muscle tone, body color, and reflex irritability.
|
| K) | A disk-shaped group of tissues in which small blood vessels from the mother and offspring intertwine but do not join.
|
| L) | Organ formation that takes place during the first two months of prenatal development.
|
| M) | A cluster of abnormalities that appears in the offspring of mothers who drink alcohol heavily during pregnancy.
|
| N) | Childbirth method similar to natural childbirth, but includes special breathing techniques.
|
| O) | A way of holding a preterm infant so that there is skin-to-skin contact.
|
| P) | 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.
|
| Q) | A test given several days after birth to assess a newborn's neurological development, reflexes, and reactions to people.
|
| R) | Childbirth method that attempts to decrease fear through education about childbirth and relaxation techniques.
|
| S) | The prenatal period of development that on average begins two months after conception and lasts for seven months.
|
| T) | The life-support system that is a bag or envelope that contains a clear fluid in which the developing embryo floats.
|
| U) | The period after childbirth when the mother adjusts, both physically and psychologically, to the process and aftermath of childbirth. This period lasts for about six weeks or until her body has completed its adjustment and returned to a near prepregnant state.
|
| V) | The life-support system that is a bag or envelope that contains a clear fluid in which the developing embryo floats.
|
| W) | The formation of a close physical bond between parents and newborn in the period shortly after birth.
|
| X) | The baby's "backward" position in the uterus that causes delivery occurs with the feet or buttocks appearing first.
|
| Y) | The inner mass of cells that develops during the germinal period. These cells later develop into the embryo.
