After puberty, the vaginal lining becomes _________ to ________.
stratified squamous epithelium; resist abrasion
 The ____________ is the site of attachment of the embryo
Most of the natural lubrication during female sexual excitement is provided by the
greater vestibular (Bartholin) glands.
The nonpregnant uterine wall consists mostly of ___________, which is composed of ___________.
myometrium; bundles of smooth muscle
Which of these is not found in the vestibule?-urinary orifice-mons pubice-vaginal orifice-labia minora-clitoris

____________ are found in both male and female external genitalia, but the ___________ is/are only found in the female.
Corpora cavernosa; vestibular bulbs
Mammary glands develop within the breasts primarily
during pregnancy.
Breast size is determined by
he amount of adipose tissue.
 Follicles are located in the
cortex of the ovary.
The earliest sign of puberty in girls is
the onset of breast development.
 ______________ are feminizing hormones.
_______________ act/s primarily in the uterus.
The appearance of pubic and axillary hair is a stage specifically called
The midlife change in estrogen and progesterone is called ___________, whereas the cessation of menstruation is called ______________.
climacteric; menopause
During climacteric, sudden ____________ may cause hot flashes.
vasodilation of cutaneous arteries
The term menstrual cycle specifically refers to
the cyclic changes in the uterus determined by shifting hormonal changes.
The ovulated egg is
a secondary oocyte.
 The ovulated egg is at
metaphase II.
The ovum finalizes meiosis
during fertilization.
Most ovulation home test kits measure _________ surge, which happens about 24 hours before ovulation.
After expelling the oocyte, the follicle becomes the ____________ and secretes __________.
corpus luteum; estrogen and progesterone
A follicle is
an oocyte enclosed in follicular or granulosa cells.
Which of these does not leave a follicle when it ovulates?
a second polar body
Oogenesis starts
during embryonic development.
In the adult ovary, more than 90% of the follicles are found as
primordial follicles.
During the follicular phase, granulosa cells secrete ____________, which stimulates secretion of ___________.
estradiol; LH
Which of these blood hormone levels reaches its maximum during the luteal phase?
____________ inhibit/s the secretion of ____________ during the female sexual cycle.
Estradiol and progesterone; FSH and LH

The _________ phase is the one associated with menstrual cramps and typically occurs __________ of the cycle.
premenstrual; days 27 to 28
During the proliferative phase of the menstrual cycle
several follicles are developing antrums.
The _________ sometimes expel/s copious fluid similar to prostatic fluid, which constitutes the female ejaculate.

During the plateau phase, the glans and clitoris swell as the _________ arteries dilate and the corpus or corpora ____________ engorge with blood.
deep; cavernosa
During ____________, the uterus is tented (erected) and the cervix is withdrawn from the vagina. Typically, the clitoris is engorged and the labia are bright red to violet due to hyperemia.

Why is breast milk superior to cow's milk for an infant?
