Term
What structures are the female reproductive system compsed of?
Definition
-Vagina
-Cervix
-Uterus
-Uterine (fallopian) tubes = oviduct
-Ovary
Term
What tissue type is the tunica albuginea of the ovary?
Definition
Dense connective tissue capsule
Term
What are the two regions of the ovary?
Definition
-outer cortex containing follicles in stroma
-inner vascularized matrix
Term
List the order of development for ovarian follicles.
Definition
-Primordial follicle
-Primary follicle
-Secondary follicle
-Mature/Graafian (Vesicular?) follicle
-Corpus luteum
-Corpus albicans
Term
What stage of meiosis is the oocyte of a primordial follicle in?
Definition
Prohpase of the the first meiotic division
Term
What type of epithelium surrounds the occyte of a primordial follicle? How does this differ from the epithelium of a primary follicle
Definition
-Simple squamous
-In a primary follicle the oocyte is initially surrounded by simple cuboidal epithelium and then later stratified cuboidal epithelium
Term
During what stage of an ovarian follicle does the zona pellucida appear?
Definition
During the primary follicle.
Term
In the primary follicle, what do the interstitial cells differentiate into?
Definition
Theca folliculi
Term
When do interstitial cells differentiate into theca folliculi cells?
Definition
In the primary follicle
Term
What is a major identifying characteristic of a secondary follicle?
Definition
Formation of an antrum
Term
What cells secrete the liquor folliculi of the secondary (antral) follicle?
Definition
Granulosa cells
Term
Which layer of the theca is estrogen secreting?
Definition
-The theca interna is estrogen secreting
Term
What is the theca externa mainly composed of?
Definition
Connective tissue and smooth mucle outer region of follicle
Term
What cells make up the cumulus oophorous?
Definition
Granulosa cells
Term
What cells make up the corona radiata?
Definition
Granulosa cells
Term
What effect does a surge of lutenizing hormone have on a mature follicle?
Definition
Causes the oocyte to compete the first meiotic division and the follicle to rupture and release the ovum.
Term
What two actions help prevent ectopic pregnancies?
Definition
-Action of the ciliated cells of the fallopian tubes help to draw ovum into the tubes
-Fimbrae swell and help ensure the ovum enters the fallopian tubes
Term
The corpus luteum funtions as what type of structure and then degenerates (in the absence of HCG) into what?
Definition
Corpus luteum functions as a temporary endocrine organ secreting estrogen and progesterone. It then degenerates into a connective tissue structure, corpus albicans
Term
What type of cells is the uterine tube lined with?
Definition
Simple ciliated columnar epithelium
Term
Where does fertilization of the ovum usually occur?
Definition
Ampulla of the fallopian tube.
Term
What are the four region of the uterine tube?
Definition
-Infundibulum
-Ampulla
-Isthmus
-Intramural part
Term
The epithelium of the fallopian tubes is composed of what two cell types? What is their function?
Definition
-Ciliated columnar cells- move the zygote toward the uterus
-Peg cells- secrete factors that activate sperm (capacitation) and provide nutrition and protection for the oocyte or zygote.
Term
What layer of the endometrium is shed during menstration?
Definition
The functionalis
Term
In what layer of the uterus are arcuate arteries located?
Definition
The myometrium=muscularis
Term
What are uterine fibroids?
Definition
Benign tumors of the uterine smooth muscle.
Term
What are two functions of the endometrial glands?
Definition
-Provide glycoproteins that nourish the embryo prior to implantation
-The bases provide new epithelium after mentration
Term
T/F. The basalis receives its blood supply from coiled arteries.
Definition
False. The basalis receives its blood supply from straight arteries which are derived from arcuate arteries. Coiled (spiral, helical) arteries supply blood to the functionalis.
Term
Where do most cervical cancers originate?
Definition
The transitional site.
Term
What is the fornix of the vagina?
Definition
Area surrounding the vaginal attachment to the cervix
Term
How can the vagina and uterus, particularly the cervix, be differentiated?
Definition
-Vagina lacks glands
-Vagina is composed of smooth muscle covered by stratified squamous nonkeratinizing epithelium.
-The cerix is covered by simple columnar mucus secreting epithelium and branched tubular glands. Has dense connective tissue with some smooth muscle fibers.
