Mullerian ducts
Answer: The Mullerian ducts become the precursor to the internal female sex
organs. This process is sort of the default development
Wolffian ducts
Answer: Wolffian ducts secrete testosterone to develop male characteristics (this is
never turned on in females, because they lack the SRY gene)
Understand the function of the SRY protein and its role in determining sex
Answer: • The Y chromosome has a sex determining region known as the SRY gene.
This turns off the progression of the Mullerian ducts so that the wolffian ducts will
then secrete testosterone and male sex organs develop
• As this takes place, the Mullerian inhibitory hormone is secreted which halts any
further development of the Mullerian ducts
By 9 months in utero, the testis are
Answer: developed and descended into the scrotum. After puberty, they will
produce sperm. Testosterone also will develop the external male genitalia
Female reproductive development occurs because there is no
Answer: SRY protein from the Y chromosome to stop it.
In females there will be no
Answer: müllerian inhibitory hormone that develops testis that develop
testosterone. Instead, estrogen will halt the wolffian ducts.
The gonads will develop into ovaries which produce the
Answer: ova and the remaining parts of the müllerian ducts (otherwise known as the
paramesonephric duct) will develop into the fallopian tubes, uterus, cervix and
vagina.
The continued presence of estrogen will develop the
Answer: external female genitalia
the anterior pituitary and hypothalamus will establish by about
Answer: 12 weeks of gestation.

Gonadotropin releasing hormone from the hypothalamus will trigger
Answer: the anterior pituitary to release luteinizing hormone and follicle-
stimulating hormone which will stimulate estrogen and progesterone production in
the ovary
Puberty begins in girls around age
Answer: 8 or 9 and in boys about age 11
About a year before actual puberty,
Answer: gonadotropin releasing hormone will begin to secrete and start to stimulate
gonadal secretion of estrogen in girls and testosterone in boys.
Estrogen will cause breast development and
Answer: maturation of the vagina, uterus and ovaries.
Testosterone in males will cause
Answer: growth of the testes, scrotum and penis
Puberty is complete when
Answer: an individual is capable of reproduction. kk
-the male produces mature sperm
-the female completes the first ovulatory menstrual period
The uterus has two major parts:
Answer: the corpus and the cervix.
The top of the corpus is referred to as the
Answer: fundus and is the widest part. The cervix is the lower part of the uterus
(sometimes called the neck). It serves as a physical barrier to bacteria.
The cervix has an internal
Answer: os (or upper opening) and an external os (or lower opening)
The external os is where the
Answer: mucus plug forms during pregnancy to keep any harmful organisms from
entering the uterus
The fallopian tubes are
Answer: the little arms that stretch from the fundus of the uterus to the ovaries on
each side.

The function of the fallopian tubes is to
Answer: carry the ova from the ovaries to the uterus
The ovaries are as also known as
Answer: the female gonads.
The main purpose of the ovaries is
Answer: the release of female sex hormones and release of ova
The ovaries have receptors for
Answer: gonadotropin hormones: LH and FSH.
- They also produce androgens which convert to estradiol.
- The corpus luteum secretes progesterone, estrogen and inhibin
The primary female sex hormones are
Answer: estrogen and progesterone
There are a few types of estrogen:
Answer: estradiol, estrone, estriol.
- Estradiol is the most potent and produced almost entirely from the ovaries.
Estrogen is necessary for the development of
Answer: reproductive organs and secondary sex characteristics and pregnancy
LH from the anterior pituitary stimulates
Answer: the corpus luteum to secrete progesterone.
LH surges at the peak of
Answer: estrogen during the menstrual cycle right before ovulation.
Progesterone is sometimes referred to as
Answer: the hormone of pregnancy.
Progesterone maintains the
Answer: thickened endometrium, engages the smooth muscle to prevent
contractions, allows for hypertrophy of the myometrium (which will help in labor
and delivery), aids in preparation of breast tissue for lactation, can also stop
maturation of the ova and prevent ovulation by suppressing FSH and LH (this is how
progesterone only birth control works)
