Chapter 27 B Class Notes BSC2086 Summer 2010
____________________________________________ a sequence of hormonal regulatory events
involving the Hypothalamus, Anterior pituitary gland, and the Testes, that is called the
______________________________________________________ (HPG) axis.
The Hypothalamus releases ______________________________________________ (GnRH) that
stimulates the Anterior Pituitary to secrete __________________________________________ (FSH)
and ____________________________ (LH).
FSH causes sustentacular (Sertoli) cells to release _____________________________________ (ABP)
that binds ___________________________ to keep its levels high in the vicinity of spermatogenic cells;
in this way FSH & ABP stimulate the cells towards spermatogenesis
LH stimulates interstitial (___________________) cells to release ____________________________,
which is the final trigger for _______________________________.
Feedback inhibition on the Hypothalamus and Pituitary results from which 2 things?
Testosterone is synthesized from __________________________.
What are 4 effects of Testosterone (slide 8):
The female reproductive system is more __________________________ in comparison, as the female
must ____________________________ and can ________________________________________ for
approximately nine months.
Ovaries are female _____________________ that do what 2 things?
Female accessory ducts include what 3 things?
Internal female genitalia include what 4 things?
Please Label the Figure on Page 2:
Ovaries are held in place by which 4 ligaments?
Please Label the second Figure on Page 2:
Blood supply of the Ovaries includes the __________________ arteries and ovarian branch of the
________________________ artery. Blood supply reaches the ovary through the
___________________________________________ and _______________________________.
Ovaries are surrounded by a fibrous _________________________________ and have which two poorly
defined regions?

The follicle of ovary has an ___________________________ surrounded by_______________________
(one cell layer thick), and _______________________when more than one layer is present.
Please briefly describe the 6 stages of Follicular development:

Please name and briefly describe the 2 Layers of the Endometrium:
(Slide 33) What is the main function of the Spiral Arteries of the Endometrium?
The Vagina is the ___________________ and organ of ____________________________.
The stratified squamous mucosa (inner layer) of the Vagina have __________________________.
Mucosa near the Vaginal orifice forms an incomplete partition called the ________________________.
What are the names of the two types of Labia?
What is the function of the Vestibular Glands?
What is the Vestibule?
What is the female erectile tissue?
Where is the Perineum located?
(Slide 42) What are 4 features of the Mammary glands?
Please describe the path of milk through the mammary gland:
Who can lactate?
Please Label the Figure below:

___________________________________ is the most common malignancy and second most common
cause of cancer death of women in the U.S.. About ___________________ of women in the general
population will experience some form of breast cancer. It Usually arises from the epithelial cells of small
ducts, and risk factors include (slide 46):
What 2 genes increase the risk for breast cancer?
_________________ of women with breast cancer have no known risk factors, although early detection
can be done with ______________________________ and _______________________________.
Following treatment, if desired the breast can be _____________________________.
What is Oogenesis and when does it begin?
Please Label the Figure on Page 6:
