Q

Endoderm (lower layer)

A

26
Congenital
The condition was present at birth
27
Gravida

28
Gravidity
Pregnancy

30
Primigravida
A woman who is pregnant for the first time
31
Multigravida
A woman who has had two or more pregnancies.
32
Parity
The number of pregnancies in which the fetus or fetuses have reached 20 weeks of gestation, not the number of fetuses (e.g., twins) born. Parity is not affected by whether the fetus is born alive or is stillborn (i.e., showing no signs of life at birth)
33
Nullipara
A woman who has not completed a pregnancy with a fetus or fetuses beyond 20 weeks of gestation
34
Primipara
A woman who has completed one pregnancy with a fetus or fetuses who have reached 20 weeks of gestation
35
Multipara
A woman who has completed two or more pregnancies to 20 weeks of gestation or more
36
Preterm
A pregnancy that has reached 20 weeks of gestation but ends before completion of 37 weeks of gestation.
37
Late preterm
A pregnancy that has reached between 34 weeks 0 days and 36 weeks 6 days of gestation
38
Early term
A pregnancy that has reached between 37 weeks 0 days and 38 weeks 6 days of gestation
39
Full term
A pregnancy that has reached between 39 weeks 0 days and 40 weeks 6 days of gestation
40
Late term
A pregnancy that has reached between 41 weeks 0 days and 41 weeks 6 days of gestation
41
Post term
A pregnancy that has reached between 42 weeks 0 days and beyond of gestation
42
GTPAL
Gravidity, term, preterm, abortions, living children.
43
Quickening
In pregnancy terms, quickening is the moment in pregnancy when the pregnant woman starts to feel or perceive fetal movements in the uterus. week 10-14.
44
Leukorrhea
White or slightly gray mucoid discharge with a faint musty odor
45
Goodell sign
Softening of the cervix, a probable sign of pregnancy, occurring during the second month.
46
Chadwick sign
Violet bluish vaginal mucous membrane and cervix that is visible from about the fourth week of pregnancy; caused by increased vascularity.
47
Hegar sign
Softening of the lower uterine segment that is classified as a probable sign of pregnancy; may be present during the second and third months of pregnancy and is palpated during bimanual examination.
48
Braxton Hicks contractions
Mild, intermittent, painless uterine contractions that occur during pregnancy. They start around 4th month. These contractions occur more frequently as pregnancy advances but do not represent true labor.
49
Ballottement
(1) Movability of a floating object, such as a fetus. (2) Diagnostic technique using palpation: a floating object, when tapped or pushed, moves away and then returns to touch the examiner’s hand. (3) Passive movement of the unengaged fetus.
50
Uterine souffle or bruit
Rushing or blowing sound of maternal blood flowing through uterine arteries to the placenta
51
The funic souffle
Which is synchronous with the fetal heart rate and is caused by fetal blood coursing through the umbilical cord, may also be heard, as well as the fetus’s actual heartbeat
52
Hyperplasia
Increase in number of cells
53
Hypertrophy
Increase in size
54
Montgomery tubercles
Hypertrophied of the sebaceous (oil) glands embedded in the primary areolae
55
hCG
Human chorionic gonadotropin
56
Goodell sign
Softening of the cervix and vagina due to hypertrophy
57
Chadwick's sign
Bluish discoloration of the cervix, vagina, and labia resulting from increased blood flow. It can be observed as early as 6 to 8 weeks after conception, and its presence is an early sign of pregnancy.
58
Braxton Hicks
Contractions are sporadic uterine contractions that start about 6 weeks into your pregnancy
59
Striae gravidarum
Stretch marks
60
Physiologic anemia
Because the plasma increase is greater than the increase in red blood cell (RBC) production, there is a decrease in normal hemoglobin values (12 to 16 g/dl blood) and hematocrit values (37% to 47%).
61
