What are the ducts or duct structures that extend from the ovaries to the exterior?
What comprises the accessory organs of the female reproductive system?
-Additional sex glands such as the mammary glands
What comprises the Internal Genitalia?
Uterine (fallopian) tubes
(ducts or duct structures that extend from the ovaries to the exterior)

Scattered throughout the Ovary and embedded in the connective tissue matrix are thousands of what?
Ovarian medulla contain what?

The External os
The Uterus receives blood from what supply's?
-Internal iliac arteries
-Ovarian and vaginal arteries (reach the Uterus by anatomosis with the uterine vessels)
What is the position of Uterus?
-Flexed forward over the bladder
-Cervix joins the vagina at right angle pointing the cervix downward and backward from the point of flexion
What postion is the Uterus in when it is flexed backward and may allow the uterus to prolapse or descend?

-2 Uterosacral ligaments - foldlike extensions of the peritoneum from the posterior surface of the uterus to the rectum
-2 Round ligaments
What are the folds of peritoneum extending from the posterior surface to the uterus to the rectum?
What are formed by the extension of the peritoneum and anterior surface of the uterus?
What are the fibromuscular cords extending from the upper outer angles of the uterus through the inguinal canals?
2 Round ligaments
What is the functions of the uterus?
Part of reproductive tract, permits sperm to ascend toward uterine tubes
The embryo is supplied with nutrients by what until the production of the placenta?
What is an organ that permits exchange of materials between mother's blood and fetal blood but keeps the two circulations separate?
What type of contractions occur during labor and help push the offspring out of mother's body?
If conception does not occur, what is shed?
Outer layers of endometrium are shed during menstruation
What lie in the upper free margin of the broad ligament and extend upward and outward toward sides of pelvis?
What are the 3 layers of the Uterine tubes?
-Mucous (directly continuous with the peritoneum lining the pelvic cavity)
The Uterine Tubes have what three divisions?
Isthmus - Upper outer angle of the uterus joins the uterus
Ampulla - Dilated middle part
Infundibulum- Funnel-shaped terminal component above and lateral over the ovary, opens to the peritoneal cavity
What are the functions of the Uterine tubes?
-Serve as transport channels for ova
-Site of fertilization
-Their secretions nurture the ovum during its migration into the endometrial cavity
Which wall of the Vagina is shorter than the other?
Anterior wall is shorter than posterior wall because cervix protrudes into its uppermost portion
What is a mucous membrane that partially to completely covers the vaginal orifice and forms a border around the external opening?
What are the functions of the Vagina?
-Lubricates and stimulates the glans penis during sex
-Receptacle for semen
-Lower portion of the birth canal
-Transports tissue and blood shed during menstruation to the exterior
What comprises the Vulva or external genitalia?
-Barholin's (or greater vestibular glands)
What part of the external genitalia is composed mainly of fat and connective tissue with sweat and sebaceous glands?
What part of the external genitalia is located medial to the labia majora and come together anteriorly to form the vestibule?
What are the 2 bean shaped glands slightly below and to the left and right of the opening of the vagina?
Greater vestibular glands (Bartholin's glands)
What are the glands located on the anterior wall of the vagina, around the lower end of the urethra. (female prostate gland)?
Lesser vestibular glands (Skene's glands)
What are some advantages of breast feeding?
-Passive immunity from antibodies present in colostrum and milk
