This will help to all first year college students partaking their education degree.Many of you will take this opportunity as also a college student like you. Have fun reading and take notes as well.

3. What is the term for the fertilized
egg?

7. -is a process of growth and
development while in a
mother’s womb.

8. -Consists three phases
• Development of the zygote
• Development of the embryo
• Development of the fetus.

9. Lasting from conception until the
developing organism becomes
firmly attached to the wall of the
uterus.

10. • As the blastocyst approaches the uterus 6 to
10 days after conception, small, burr-like
tendrils emerge from its outer surface. When
the blastocyst reaches the uterine wall, these
tendrils burrow inward, tapping the pregnant
woman’s blood supply.

11. Lasting from the third to the
eighth prenatal week, during
which the major organs and
anatomical structures take shape.

12. Lasting from the ninth prenatal
week until birth; during this period,
all major organ systems begin to
function and the fetus grows
rapidly.

13. • Blastocyst - Name given to the ball of cells
formed when the fertilized egg begins to divide.
• Embryo - Name given to the prenatal organism
from the third to the eighth week after
conception.
• Implantation - The burrowing of the blastocyst
into the lining of the uterus

15. Placenta was form in the uterus and it has three
functions.
• To provide oxygen and nutrients to the
baby.
• Removes harmful waste and carbon dioxide
from your baby.
• Produces hormones that help your baby to
grow

16. • Amnion-providing a cushion against mechanical
injury.
• Chorion-to eliminate fetal waste.
• Placenta-an organ that develops in the uterus
during pregnancy
• Umbilical Cord-is a bundle of blood vessels that
develops during the early stages of embryological
development.

17. • Vernix- a white, cheesy-looking substance
that coats the skin of your baby while in the
uterus
• Lanugo -soft, fine hair covering a fetus while
inside the uterus
• Age if viability-between 23 and 24 weeks
gestational age.

18. • The period of the embryo begins at
implantation, which occurs around the third
week of pregnancy, and lasts until the eighth
week. During this time, the embryo undergoes
significant development and forms the
foundation for the baby's growth.

19. • One of the key aspects of this period is the
differentiation of the embryonic disk into
three distinct layers of cells: the ectoderm,
mesoderm, and endoderm.

20. • The outer layer, known as the ectoderm,
plays a crucial role in the development of the
nervous system. It will eventually become the
brain and spinal cord. Additionally, the
ectoderm gives rise to the skin and hair, which
are important external features of our bodies.
ECTODERM

21. • Moving on to the middle layer, called the
mesoderm, this layer is responsible for forming
various structures in the body. It develops into the
muscles, bones, and connective tissues that provide
support and movement. Furthermore, the
mesoderm plays a vital role in the formation of the
circulatory system, including the heart and blood
vessels.
MESODERM

22. • Lastly, we have the inner layer called the
endoderm. The endoderm is responsible for
the development of the digestive system,
including the stomach and intestines. It also
gives rise to the lungs, urinary tract, and other
vital organs such as the pancreas and liver.
ENDODERM

23. • The period of the fetus refers to the last
seven months of pregnancy, characterized by
rapid growth and refinement of all organ
systems. It is during this time that the fetus
undergoes significant changes and prepares
for life outside the womb.

25. -is an agent or factor which
causes malformation of an
embryo.

26. -The term sensitive period refers
to the notion that the effects of
environmental stimuli on the
developing organism are stronger
during certain periods of
development.

27. -Rubella is a contagious viral
infection best known by its
distinctive red rash.

28. - is an infection with a parasite
called Toxoplasma gondii.

29. -Syphilis is a preventable and
curable bacterial sexually
transmitted infection (STI).

31. • This is the stage of pregnancy where the
mother and the family become the most
anxious. -
• Preparing for birth is highly recommended
and important.

32. • Parents-to be should take classes to learn the most
recent way of doing infant CPR, feeding, bathing,
changing and other things that they will be doing every
day with their baby. Preparing the suitcase for the
hospital about 1 or 2 months in advance is necessary
since babies sometimes come sooner than expected.
Learning breathing and relaxation techniques to use
through the birthing process come in handy.

33. • The health and medical
needs a baby needs all
depends on the birth weight
and size, and any genetic
vulnerabilities.
