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

- 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

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
