chapter 8 Flashcards
Gynecology
is the study of the female reproductive system (organs, hormones,
and diseases)
obstetrics
is a specialty concerned with
pregnancy and the delivery of the fetus
neonatology
is the study of the care and
treatment of the newborn.
cul-de-sac
Midway between the uterus and the rectum is a region in the abdominal cavity
Bartholin glands
two small, rounded glands on either side of the vaginal orifice.
These glands produce a mucous secretion that lubricates the vagina.
clitoris
organ of sensitive, erectile tissue located anterior to the vaginal orifice and in front of the
urethral meatus
perineum
region between the vaginal orifice and the anus
vulva.
The external genitalia of the female are collectively called the vulva
labia majora, labia minora
outer lip. inner lip
hymen
membrane partially covering the entrance to the vagina,
utero-ovarian ligament
Each ovary [1] is
held in place on either side of the uterus by
ovarian follicles
Within each ovary are thousands of small sacs
ovum, corpus luteum
During ovulation, an ovum matures; its follicle ruptures through
the surface and releases the ovum from the ovary. A ruptured follicle fills with a yellow,
fat-like material. It is then called the corpus luteum [5], meaning yellow body. The corpus
luteum secretes hormones (both estrogen and progesterone) that maintain the very first
stages of pregnancy.
A fallopian tube
Collectively, the
fallopian tubes, ovaries, and supporting ligaments are the adnexa (accessory structures) of
the uterus.
fimbriae
The finger-like ends of the fallopian tube are the fimbriae [7]. They catch the
egg after its release from the ovary. Cilia (small hairs) line the fallopian tube and, through
their motion, sweep the ovum along. It usually takes the ovum about 2 to 3 days to pass
through the fallopian tube.
corpus
body of the organ
endometrium
The inner layer, a specialized epithelial mucosa of the
uterus is the endometrium [9];
myometrium
the middle, muscular layer of the uterine wall is t
uterine seros
and the outer, membranous tissue layer, a
lining that produces a watery, serum-like secretion. The outermost layer of an organ in
the abdomen or thorax is known as a serosa.
cervix
The narrow, lowermost portion of the uterus
glandular tissue
contains milk glands or lobules that develop
in response to hormones from the ovaries during puberty
lactiferous (milk-carrying) ducts [3], and sinuses (cavities) [4]
that carry milk to the nipple, which has small openings for the ducts to release their milk.
mammary papilla [
The breast nipple
areola
the dark pigmented area around the
mammary papilla is
parturition, lactation
giving birth, secrete milk
chorion
the outermost membrane
that surrounds the developing embryo
amnion,
he innermost of the embryonic
membranes, holds the fetus suspended in an amniotic cavity surrounded by a fluid called
the amniotic fluid.
human chorionic
gonadotropin (hCG).
As the placenta develops in the uterus, it produces its own hormone. When women test their urine with a pregnancy test kit, presence or
absence of hCG confirms or rules out that they are pregnant. This hormone stimulates the
corpus luteum to continue producing hormones until about the third month of pregnancy,
when the placenta takes over the endocrine function and releases estrogen and progesterone.
Progesterone maintains the development of the placenta. Low levels of progesterone
can lead to spontaneous abortion in pregnant women and menstrual irregularities in
nonpregnant women.
cephalic
presentation
In a normal delivery position, the baby’s head appears first
afterbirth.
The expelled placenta is
follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
The events of menstruation and pregnancy depend on hormones not only from the ovaries
(estrogen and progesterone) but also from the pituitary gland. The pituitary gland secretes
follicle-stimulating hormone (FSH) and luteinizing hormone (LH) after the onset of
menstruation. As their levels rise in the bloodstream, FSH and LH stimulate maturation
of the ovum and ovulation. After ovulation, LH in particular influences the maintenance
of the corpus luteum and its production of estrogen and progesterone
Oral
contraceptives (birth control pills) work in the same way
During pregnancy, the high levels of estrogen and progesterone from the ovary and
placenta cause the pituitary gland to stop producing FSH and LH. Therefore, while a
woman is pregnant, additional eggs do not mature and ovulation cannot occur. Oral
contraceptives (birth control pills) work in the same way
IUD (intrauterine device
A health care
professional inserts the IUD, a small device designed to remain inside the uterus. It works
by preventing implantation of the embryo. Birth control pills and an IUD do not protect
a woman against sexually transmitted infections such as that caused by HIV
FSH Pituitary gland-Ovary: Stimulates maturation of the ovum
LH Pituitary gland-Ovary: Stimulates ovulation
Estrogen Ovary
Placenta (during pregnancy)
-Uterus: Builds up the endometrial lining
Progesterone Ovary (corpus luteum)
Placenta (during pregnancy)
-Uterus: Sustains uterine lining and placenta

hCG Placenta-Ovary (corpus luteum)
Sustains pregnancy

Fallopian tubes, ovaries, and supporting ligaments.
