Module 3 Fetal Growth & Development(100% Correct
answers)
Learning Outcome: Identify the key concepts of fetal growth and development.
Growth:
Growth Results from: correct answersIncreasing size of the fetus. Occurs throughout normal
pregnancy.
Early pregnancy: increase in number of fetal cells
Mid to late pregnancy: growth in the size of the fetal cells
Learning Outcome: Explain the relationship between fetal growth, development and gestational
age.
what is used to determine growth and development?
Are they the same? correct answersgestational age -> development
weight -> growth
No
Development def correct answersFunctional and structural changes that occur in the fetal organ
systems and occur throughout pregnancy.
Includes:
- differentiation of cells and tissues
- organization of cells and tissues into organ systems
-cell growth
Appropriateness for gestational age correct answersrelationship btw fetal growth and
development. Important in assessing health of fetus
Preterm or premature correct answersborn before completion of 37 weeks gestation
Late preterm (%) correct answersborn between 34 weeks and 37 weeks of gestation.
Fastest growing subset of preterm infants;
account for 74% of all preterm births
Term correct answersborn bet beginning of week 38 and end of week 42 gestation
Post-term (post-date) correct answersborn after week 42 gestation
Postmature correct answersBorn after 42 weeks gestation & showing effects of progressive
placental insufficiency
First Trimester
,Second Trimester
Third Trimester correct answersweeks 1-13
weeks 14-26
weeks 27-40
cephalocaudal pattern correct answersembryo-fetus develops and matures from head towards
extremities
both physically and neurologically
Fetal growth and development
During the first 18 weeks after conception +weight correct answersFetal growth and
development is extremely rapid
embryo grows from a microscopic egg to a fully formed fetus weighing approximately 400
grams
organogenesis correct answersfetus' organs and structures are formed and begin to function
The fetal brain when & uses what correct answersextremely rapid growth and development
during this early period,
uses most of the total nutrients available to the embryo-fetus
After 18 weeks, or the last 20 to 22: G vs.D, weight correct answersFetus focuses more on
growth than development
Fetal weight goes from 400 grams at 18 weeks to 3400 grams at birth
Fetal organs and structures do continue to develop
preconception period correct answersbegins on the first day of a woman's menstrual cycle and
lasts until conception occurs
first two weeks of menstrual cycle correct answersprepares for pregnancy:
Ripening egg or ovum
thicker, richer lining in uterus to receive & nourish egg
middle of her cycle correct answersegg can be released
egg has a life span correct answers12 to 24 hours
intercourse delivers correct answers150-250 million sperm
sperm past cervix correct answers10th of original
15-25 million
enter a woman's fallopian tubes correct answers2000 sperm
half of these go to wrong tube
, sperm reach egg correct answers100-200
Conception correct answersSperm finds and penetrates the mature egg
egg's reaction correct answersMembrane toughens so that no other sperm can penetrate
sperm's nucleus correct answersjoin to make a single set of 46 chromosomes
process of fusion correct answers30 minutes
conception now complete
fetal age: 0-2
stage:
development Milestone: correct answersstage: pre-embryonic
egg differentiates into different specialized cells; travels down fallopian tube and implants in
uterus
fetal age: 2-8
stage:
5 development Milestone: correct answersEmbryonic
Rapid growth and development; organogenesis occurs and most organs begin to function;
embryo's heart is beating; its head is disproportionately large, due to rapid brain development;
arms and legs have joints, and fingers are distinct
placenta timeline correct answers- develops in first week
- by third week: fetal capillaries within the villi to absorb nutrients and oxygen and to excrete
wastes.
-placenta grows the number of villi proliferate until approximately 18-20 weeks after conception
fetal age: 9-term
stage:
4 development Milestone: correct answersFetal
placenta fully formed and functioning;
fetal organs continue to develop;
fetus viable at 22 weeks; significant increase in size (weight) in last 10-12 weeks
Learning Outcome: Discuss the functions of the placenta, fetal membranes and amniotic fluid.
placenta formation (cells, branching, after birth) correct answersonly organ that contains cells
from two different individuals
-The maternal component of the placenta is formed by the decidua basalis (the endometrium or
uterine lining underneath the site of implantation).
