Family Dynamics- HGD

Vocabulary flashcards covering family development systems, parental care precautions, genetic mapping, and prenatal diagnostic procedures.

The Family

A network of interdependent relationships in which each person's behavior directly or indirectly influences that of others.

Third Parties

Individuals present in family interactions, such as grandparents, who serve as either supports or barriers to child development.

Effective Coparenting

A pattern that occurs when a marital relationship is warm and considerate, leading parents to mutually support each other, praise and stimulate their children, and scold less.

Ineffective Coparenting

A pattern that occurs when a marital relationship is tense and hostile, causing parents to interfere with each other, remain unresponsive to needs, and trigger serious behavior problems in children through disrupted emotional security.

Ultrasound

A diagnostic method using high-frequency sound waves beamed at the uterus to create a screen picture revealing fetal size, shape, placement, age, gross physical defects, or multiple pregnancies; using it 5 or more times may increase chances of low birth weight.

Maternal Blood Analysis

A prenatal procedure available by the 2nd month of pregnancy, where fetal cells in the maternal bloodstream are evaluated to detect kidney disease, abnormal closure of the esophagus, or neural tube defects such as spina bifida.

Parental Precautions

Recommended measures prior to and during pregnancy, including physical exams, genetic risk evaluation, eliminating toxins like smoking and drinking, ensuring nutrition with folic acid, and seeing a doctor after 12 months of unsuccessful conception.

Pedigree

A picture of a family tree identifying affected relatives, used to estimate the likelihood of parents having a child with a genetic condition.

Prenatal Diagnostic Methods

Medical procedures that permit the detection of developmental problems before birth.

Fetoscopy

A procedure involving a small tube with a light source inserted into the uterus to inspect fetal limbs and face, and to collect fetal blood samples for diagnosing conditions like hemophilia, sickle cell anemia, and neural defects.

Amniocentesis

The most widely used prenatal diagnostic technique, where a hollow needle is inserted through the abdominal wall to collect uterine fluid and inspect cells for genetic defects.
