CH 27 jarvis female geniturinea Flashcards
external genitalia are called the
- clitoris
- labia majora
- labia minora
vulva, or pudendum
is a round, firm pad of adipose tissue covering the symphysis pubis.
mons pubis (cover symphysis pubis)
are two rounded folds of adipose tissue extending from the mons pubis down and around to the perineum
labia majora
Inside the labia majora are two smaller, darker folds of skin, the
labia minora.
labia minora are joined posteriorly by a transverse fold, the
frenulum, or fourchette.
is a small, pea-shaped erectile body, homologous with the male penis and highly sensitive to tactile stimulation.
clitoris
labial structures encircle a boat-shaped space, or cleft, termed the
- urethral meatus and vaginal orifice are visible
- ducts of the paraurethral (Skene) glands and the vestibular (Bartholin) glands are present but not visible.
vestibule.
appears as a dimple 2.5 cm posterior to the clitoris.
urethral meatus
Surrounding the urethral meatus are the tiny, multiple
-Their ducts are not visible but open posterior to the urethra at the 5 and 7 o’clock positions.
paraurethral (Skene) glands
is posterior to the urethral meatus. It appears either as a thin median slit or a large opening with irregular edges, depending on the presentation of the membranous hymen
vaginal orifice
is a thin, circular or crescent-shaped fold that may cover part of the vaginal orifice or may be absent completely
hymen
posterior to the vaginal orifice are which secrete a clear lubricating mucus during intercourse. Their ducts are not visible but open in the groove between the labia minora and the hymen.
two vestibular (Bartholin) glands,
, a flattened, tubular canal extending from the orifice up and backward into the pelvis
- 9 cm long and sits between the rectum posteriorly and the bladder and urethra anteriorly.
vagina (internal genitalia)
nulliparous (never given birth) female the cervix appears as a smooth doughnut shape with a small circular hole, or
-After childbirth the os is slightly enlarged and irregular.
os
vagina & cervis (stratified squamous) + OS (columnar) meet
squamocolumnar junction (not visible)
Behind the posterior fornix another deep recess is formed by the peritoneum. It dips down between the rectum and cervix to form the
rectouterine pouch, or cul-de-sac of Douglas
is a pear-shaped, thick-walled, muscular organ. It is flattened anteroposteriorly,
- freely movable, not fixed, and usually tilts forward and superior to the bladder (a position labeled as anteverted and anteflexed,
uterus
are two pliable, trumpet-shaped tubes, 10 cm in length, extending from the uterine fundus laterally to the brim of the pelvis.
fallopian tubes
are located one on each side of the uterus at the level of the anterior superior iliac spine.
-develop ova (eggs) and the female hormones.
two ovaries
-At birth the external genitalia are engorged because of the
presence of maternal estrogen. (infant)
ovaries are located in the abdomen during childhood. The uterus is small with a straight axis and no anteflexion
infant genital development
stimulate the growth of cells in the reproductive tract and the development of secondary sex characteristics.
puberty estrogens
are breast development (thelarche) and pubic hair development, beginning between the ages of 8 to 10 years (mean = 11.6 years).
first signs of puberty
because of the occasional failure to ovulate
-With menarche the uterine body flexes on the cervix. The ovaries now are in the pelvic cavity.
Irregularity of the menstrual cycle is common during adolescence
is helpful in teaching girls the expected sequence of sexual development
Tanner’s table on the 5 stages of pubic hair development (sexual maturity rating [SMR])
signs of the growing fetus
- changes in the cervix on internal examination.
first missed menstrual period the genitalia show
becomes globular in shape and is too large to stay in the pelvis.
By 10 to 12 weeks’ gestation, the uterus
has an oval shape. It rises almost to the liver, displacing the intestines superiorly and laterally.
20 to 24 weeks, the uterus
and are thick, white, and more acidic because of Lactobacillus acidophilus, which changes glycogen into lactic acid. The acidic pH keeps pathogenic bacteria from multiplying in the vagina, but the increase in glycogen increases the risk for candidiasis (commonly called a yeast infection) during pregnancy.

cervical cancers result as a long-term consequence
cervical cancer screening by a ? every 3 years from ages 21 to 65 years
Papanicolaou test
is cessation of the menses
-Ovaries stop producing progesterone and estrogen
Menopause
of decreased myometrium (decreased smooth muscle tissue of uterus)
uterus shrinks in size because
not palpable after menopause
ovaries
- Ovulation still may occur sporadically after menopause.
- sacral ligaments relax, and the pelvic musculature weakens; thus the uterus droops. The cervix shrinks and looks paler with a thick, glistening epithelium.
changes to genital after menopause
vagina becomes shorter, narrower, and less elastic. Without sexual activity the vagina atrophies to one-half its former length and width
vagina alterations
Decreased vaginal secretions leave the vagina dry and at risk for irritation and pain with intercourse
(dyspareunia)
alkaline, and glycogen content decreases from the decreased estrogen. These factors also increase the risk for vaginitis because they create a suitable medium for pathogens.
vaginal pH becomes more
