What is the function of the mucosal lining in the vaginal wall?
The mucosal lining of the vagina lies in folds and can extend which is important when the
vagina serves as the birth canal and it also facilitates intercourse.
The is a fat pad located in front of the pubic symphysis and is covered with hair after
puberty.

Describe the structure of the mammary glands
A mammary gland contains one to two dozen lobules, each with its own mammary duct. The
duct begins at the nipple and divides into numerous other ducts ending in blind sacs called
alveoli. In a non-lactating breast, the ducts far outnumber the alveoli since alveoli are made up
of cells that can produce milk.
Is milk produced during pregnancy?
Milk is not produced during pregnancy because prolactin is needed for lactation (milk

production) to begin. Prolactin is suppressed by estrogen and progesterone.
What is colostrum?
A yellowish-white fluid which has a similar composition to milk but contains a higher
concentration of protein
What is oogenesis?
Oogenesis is the production of eggs in the ovaries which occurs during development of the fetus
in the womb and is complete by the time of birth.
Describe the steps of oogenesis from primary oogonia to a mature ovum.
Oogonia (Female stem cells), undergo mitotic division into two daughter cells known as primary
oocytes. These primary oocytes are covered by follicles, known as primary follicles. This process
is completed by birth. The anterior pituitary gland starts to secrete follicle-stimulating hormone
(FSH) when a female reaches puberty. FSH causes a few follicles to mature each month. The
primary oocyte in the follicle undergoes its first meiotic division into two daughter cells: the
secondary oocyte and the first polar body. If the secondary oocyte is united with a sperm after
ovulation the second meiotic division occurs which produces a second polar body and an ovum
with 23 chromosomes.
The female reproductive system includes what internal organs?
Internal organs: the ovaries, the oviducts (fallopian or uterine tubes), the uterus, and the vagina.
What is ovulation? How often does it occur?
The release of a mature egg; occurs approximately every 28 days.
What is the ovarian cycle?
An egg is released from the ovarian follicle.
What does the ovarian follicle become after ovulation?
