Corpora cavernosa; vestibular bulbs
Mammary glands develop within the breasts primarily

______________ 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

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 __________.

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.

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.

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During ____________, the uterus is tented (erected) and the cervix is withdrawn from the vagina.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.

estriol; estradiol
The _________________ provides fetal nutrition and secrets hormones that regulate pregnancy and fetal development.
What is the longest stage of labor
the dilation (first) stage
Milk ejection, stimulation of nerve endings in the ____________ leads to the release of ______________ from the pituitary.
nipple and areola; oxytocin
Why is breast milk superior to cow's milk for an infant?
