LAMCCD 1: Week 4

Page 2: LAMC CD 1: Week 4. The age of viability- is the point in the pregnancy when the fetus is likely to survive outside the womb… La edad viable- el período.

The age of viability- is the point in the pregnancy when the fetus is likely to survive outside the womb…

La edad viable- el período a partir de 28 semanas después de la concepción, cuando el feto puede ser capaz de sobrevivir fuera del útero.

Procedures to monitor growth Ultrasound- high-frequency sound waves are

bounced off of the fetus’s body which produces an outline of the soft tissue

(Ultrasonido- Procedimiento médico que utiliza ondas acústicas para producir un imagen del feto)

Chorionic Villus Sampling (CVS)- a needle is inserted into the placenta, chorion cells are removed

Muestra de vellosidad coriónica- Procedimiento medico en el cual se obtiene y se analiza una muestra del tejido fino del corion

Amniocentesis- a needle is inserted through the mother’s abdomen .

La Amniocentesis-Procedimiento medico en el que se obtiene y es analizada una muestra del líquido amniótico.

Teratogens/Teratógeno

Page 7: LAMC CD 1: Week 4. The age of viability- is the point in the pregnancy when the fetus is likely to survive outside the womb… La edad viable- el período.

Teratogens/Teratógeno

Nongenetic agents that can cause malformation in the embryo / fetus.El agente (no genético) que causa el

desarrollo abnormal prenatal. 1930’s –X-rays could cause growth retardation;

“microcephaly”; desarrollo retrasado del cerebro. Mid 1940’s –a pregnant mother who contracted rubella,

had a high risk of a baby congenital abnormalities of the eye, ear, heart, & brain; anormalidades del ojo, oreja, corazón, o el cerebro.

1960’s – thalidomide; many babies of these mother’s born w/ defective limbs; niños nacidos sin brazos o piernas completos.

6 features how teratogens act:1) Depends on the genetic makeup of the

organism exposed to the teratogen… depende en los genes del organismo.

2) The effect on development, depends partly on timing the organism was exposed to it…el efecto depende cuando el organismo fue exponido al teratógeno

3) The effect of a teratogen may be unique… it…el efecto de un teratógeno puede ser único o específico.

4) The abnormal development caused by teratogens may be severe…el desarrollo abnormal puede ser grave.

5) Teratogens differ in how they gain access to the fetus… hay distintas maneras como un teratógeno tiene acceso al feto.

6) The fetus’s dosage of the harmful agent…hay que tomar en cuenta la dosis del teratógeno, y cada mujer o feto (individual).

Types of Teratogens/ Tipos de Teratógenos

1) Drugs/ Drogas: any substance other than food intended to affect the body; cual quier sustancia que no es comida que tiene la intención de …

Drugs can be illegal or legal.2) Environmental Chemicals/ Químicos en

el ambiente: include insecticides, herbicides, fungicides, detergents, food additives, etc.

3) Maternal Infectious Diseases/ Enfermedades infecciosos maternales : several infections in the mother can damage the fetus.

Stages of birth/ Etapas de dar a luz

Stages of (Vaginal) ChildbirthEtapas de dar a luz

1) Dilation- longest stage of labor; primiporous mothers & multiparous mothers.

El cervico se abre

2) Completely Dilated 3) Afterbirth

The baby’s head passes through the cervix & into the birth canal

El cervico esta completamente abierto

Less than 1 hour; contractions push the placenta out Menos de 1 hora;
