Explain this illustration,
|
Ovarian follicles, contain oocytes, FSH stimulates the follicles to undergo development, and one follicle matures completely, rupturing and expelling its oocyte, the remnants of the ruptured follicle become the corpus luteum (which later degenerates and becomes the corpus albicans)
|
|
|
Order of maturation of an oocyte!
|
Primordial follicles-->primary follicles-->secondary follicles-->vesicular follicle-->corpus luteum-->corpus albicans
|
|
Where is this?
Identify A and B |
Ovary
A-primary follicle B-primordial follicle |
|
What is this?
Identify the labels. |
Antral Follicle-
A-theca cells b-zona pellucida C-granulosa cells d-antrum |
|
|
What is the function of a granulosa cell?
|
Secretes estradiols, converting them from androgens (using aromatase) that are secreted from the theca cell, stimulated by FSH
|
|
|
What is the function of a theca cell?
|
secretes androgens that are converted by granulosa cells to estrogen.
|
|
What is this?
Identify the labels |
Mature follicle
A-corona radiata b-cumulus oophorus c-theca cells D-granulosa cells |
|
What is this?
|
Corpus luteum, contains granulosa and theca lutein cells (you can only tell granulosa b/c they are bigger).
|
|
|
What do granulosa lutein cells secrete?
|
Progesterone and estrogen (as opposed to just estrogen before they are luteinized)
|
|
What is this? When would it appear?
|
Corpus albicans, appears 4-10 days if there is no pregnancy as cells die and are replaced with connective tissue.
|
|
|
What maintains the corpus luteum?
|
LH, and then if there is a pregnancy the fetus produces HCG for 4-5 months to maintain it.
|
|
What is wrong with this ovary!
|
it is post menopausal-it doesn't have follicles anymore.
|
|
|
Name the order of the uterine tubes?
|
Infundibulum-ampulla-isthmus-intramural region
|
|
What is this? What kind of cells does it have?
|
Uterine tube-has longitudinal folds in a labyrinth, has ciliated cells that help move the egg, and secretory cells that are important for that maturation of sperm
|
|
|
What are the three layers of the uterus and their properties?
|
Endometrium-inner layer
---has a basal and functional layer Myometrium-middle layer ---3 layers of smooth muscle Perimetrium-very outer thin lining ---adventitia where it rests on the bladder and serosa everywhere else |
|
|
What kind of cells line the surface of the endometrium?
|
ciliated and secretory simple columnar
|
|
|
What do uterine glands secrete?
|
Glycogen
|
|
Explain the blood supply to the endometrium and how it varies by cycle?
|
Blood from the uterine artery flows into the arcuate arteries (myometrium), they branch to form the straight artery (basal layer) and the spiral artery (functional layer)...the functional layer becomes ischemic as these arteries die and is sloughed off.
|
|
Match these images with their menstrual phase.
|
A-proliferative phase
b-menstrual phase c-secretory phase (squiggles) |
|
What is this?
|
Cervix,
covered in stratified sqamous epithelium on one side (vaginal) and simple columnar on the other (uterine) has glands which secrete a thick secretion during pregnancy, creates the acidity in that environment as well, becomes more watery during ovulation/intercourse to facilitate pregnancy |
|
Where is this? What kind of epithelium is it
|
Vagina-
non keratinized stratified squamous, has a thick muscular layer, and an adventitia |
|
|
What hormone creates the proliferative phase?
|
Estrogen
|
|
|
What hormone rules the secretory phase?
|
Progesterone
|
|
What is the difference between these two glands?
|
Active has less CT and more complex compound alveolar tubular glands in it. The inactive has more CT and fat in it.
Estrogen and progesterone help to develop the glandular cells in the active breast. |
|
What is this? Identify A and B
What kind of epithelium surrounds the duct? |
An Active mammary gland,
A=myoepithelial cell-acted on by oxytocin to secrete the milk b-plasma cell-secretes IgA simple cuboidal |
|
|
What kind of a mode of secretion is milk production?
|
Apocrine for the fat and merocrine for the proteins.
|
|
What is this? What kind of epithelium does it have?
|
Lactiferous duct, terminal ducts come together to make one lactiferous duct,
stratified cuboidal epithelium |
|
