Prenatal Development & Care Flashcards
It is an early sign and symptoms of pregnancy that indicate pregnancy, although can be misleading
Missed period
It is an early sign and symptom of pregnancy which indicates increased production of the female hormones estrogen and progesterone to prepare for producing milk.
Tender, swollen Breast
It is an early sign and symptom of pregnancy which may occur about 10 to 14 days after fertilization when the ovum attaches to the lining of the uterus. Women may also cramp as the uterus enlarges.
Slight bleeding or cramping
It is an early sign and symptom of pregnancy
in which morning sickness may begin as early as 2 weeks after conception but usually around 4 to 8 weeks and may occur at any time of day.
Nausea with or without vomiting
It is an early sign and symptom of pregnancy
in which a woman experiences enlarging the uterus during the first trimester exerting pressure on the bladder.
Frequent urination
It is an early sign and symptom of pregnancy
in which a woman experiences her heart pumping harder and faster to carry nutrients to the fetus. Stepped-up production of hormones takes extra effort. Progesterone depresses the central nervous system and may cause sleepiness
Fatigue
It is an early sign and symptom of pregnancy
in which a woman experiences her flood of hormones early in pregnancy can produce emotional highs and lows.
Mood swings
It is an early sign and symptom of pregnancy
in which a woman experiences an increase in progesterone may slow digestion, so food passes more slowly through the intestinal tract.
Constipation
It is an early sign and symptom of pregnancy
in which a woman experiences hormonal changes that may alter her food preferences, especially during the first trimester. A heightened sense of smell may trigger nausea in response to certain foods.
Food aversions
It is an early sign and symptom of pregnancy
in which a woman experiences lightheaded feeling may be triggered by blood vessel dilation and low blood pressure or by low blood sugar.
Faintness and dizziness
It is an early sign and symptom of pregnancy
in which a woman experiences this during ovulation, each month and then drops during menstruation. When menstruation ceases, temperature remains elevated.
Raised basal body temperature
It identifies the presence of human chorionic gonadotropin, which, under normal circumstances, is produced only by embryos and fetuses.
Pregnancy tests
a ______ pregnancy test tells a woman a conception has occurred.
positive
Typical prenatal development begins with fertilization and ends with birth, lasting between ____and 280 days (from 38 to 40 weeks)
266 and 280 days
(38 to 40 weeks)
What are the three periods of prenatal development?
Germinal, embryonic, and fetal
What are the two principles of growth?
Cephalocaudal principle and Proximodistal Principle
It is a principle of growth from Latin, meaning “head to tail” which dictates that development proceeds from the head to the lower part of the trunk
Cephalocaudal principle
It is a principle of growth from Latin, meaning “near to far” Development proceeds from parts near the center of the body to outer ones
Proximodistal Principle
_____ is a prenatal period from fertilization to 2 weeks
GERMINAL PERIOD
It is a prenatal period that includes the creation of fertilized eggs, called zygote, cell division, and the attachment of the zygote to the uterine wall
GERMINAL PERIOD
During this prenatal period, the zygote divides, becomes more complex, and is implanted in the wall of the uterus.
GERMINAL PERIOD
At a germinal stage, within 36 hours after fertilization, the zygote enters a period of ______ also called mitosis
rapid cell division and duplication
______ hours after fertilization, it has divided first into 16 and then into 32 cells; a day later, it has 64 cells.
Seventy-two
While the fertilized ovum is dividing, it is also making its way through the _______ to the uterus, a journey of 3 or 4 days, and its form changes into a blastocyst
fallopian tube
It is a fluid-filled sphere, which floats freely in the uterus until the sixth day after fertilization, when it begins to implant itself in the uterine wall
blastocyst
In this stage of prenatal period, mas susceptible to the changes of environment, pagnakagkaroon ng problem sa cell division ang tendency catstrophic yung reaction at ika-copy ang error na ito at hinid magiging maganda yung germinal period.
GERMINAL PERIOD
Only about __to ____ percent of fertilized ova complete the task of implantation and continue to develop.
10 to 20
It is the attachment of the zygote to the uterine wall, that takes place about 11 to 15 days after conception.
Implantation
It consists of an inner mass of cells that will eventually develop into the embryo
blastocyst
.
differentiation of these cells–
It is an outer layer of cell that later provides nutrition and support for the embryo
Trophoblast
When does cell differentiation begin?
Before implantation
some cells around the edge of the blastocyst cluster on one side to form_____
embryonic disk
A thickened cell mass from which the embryo begins to develop. This mass will differentiate into three layers.
embryonic disk
What is the inner layer of the embryonic disk which becomes the digestive system, liver, pancreas, salivary glands, and respiratory system?
Endoderm
What is the upper layer of the embryonic disk which will become the outer layer of skin, nails, hair, teeth, sensory organs, and the upper nervous systems, including the brain and spinal cord?
Ectoderm
