|
What structure surrounds the ovary?
|
Tunica Albuginea
|
|
|
What composes the primary follicle?
|
Oocyte with one layer of follicular cells.
LOCATED at the VERY EDGE of ovary. |
|
|
What occurs to trigger follicular development?
Where is the zona pellucida located? |
FSH triggers granulosa cells to convert androstenedione to estradiol, which triggers follicular growth.
Zona granulosa proliferates. ZP is located in between oocyte and follicular/ granulosa cells. |
|
|
What is a hallmark of a secondary follicle?
|
ANTRUM! Fluid-filled space in egg.
Theca externa/interna are being developed. |
|
|
What are hallmarks of a graafian follicle?
|
Graafian follicle = mature follicle.
Oocyte is surrounded by CORONA RADIATA. Fluid-filled antrum is MUCH LARGER. Haploid 2n, |
|
|
What is a glassy membrane?
|
Glassy membrane is a hallmark of atretic follicles.
Characterized by the thickening of the basement membrane between the granulosa and theca interna. |
|
|
The presence of a corpus albicans is indicative of what?
|
Fertilization HAS NOT OCCURED.
|
|
|
What does the corpus luteum secrete upon ovulation and release of egg from ovary?
|
Granulosa/follicular cells give rise to LUTEIN cells and secrete progesterone and estrogen.
Thecal interna cells give rise to theca LUTEIN cells and secrete androstenedione and progesterone. |
|
|
What cells remain in ovary beyond egg release?
|
FOLLICULAR/GRANULOSA LUTEIN (estrogen and progesterone) and THECAL LUTEIN (androstenedione and progesterone)
|
|
|
What cell types are present in ampulla of fallopian tubes?
|
Ciliated AND non-ciliated cell types. Non-ciliated cells secrete substance that is propelled to uterus by ciliated cells.
|
|
|
What happens if female has Karteneger's syndrome
|
Problems with motility (dynein and other proteins). Problems with fertility?
Egg may not be properly propelled towards uterus |
|
|
What are the three layers of the uterus?
|
Outer serosa
Myometrium (smooth muscle and connective tissue of the uterus) Endometrium (epithelium, basal lamina, and glands) - basalis layer (provides base, lamina propia, etc) - functionalis layer (sloughed off and replaced with each menstrual cycle) |
|
|
What do nuclei in myometrium look like?
|
Elongated nuclei...standard for smooth muscle cells.
|
|
|
What changes does the myometrium undergo during pregnancy?
|
Hypertrophy, Hyperplasia, INCREASE IN COLLAGEN (more support)
|
|
|
Which stage of secretory phase will have a more spongy appearance?
|
LATE SECRETORY PHASE
|
|
|
What are the three layers of vagina and how are they organized?
|
Adventitia (dense connective tissue), Mucosa (stratified squamous, lamina propia, loose connective), Muscular layer (smooth muscle)
From outer to inner: Outer adventitial layer --> Muscular layer --> Lamina propia --> Stratified squamous epithelium |
|
|
What is a schematic of the breast?
|
Rib/chest wall forms POSTERIOR aspect of breast.
Breast contains lobules with alveoli (different developmental stages based on age, pregnancies, etc). Lobules connect with ducts and tubules that travel to nipple. Each tube is independent until it reaches nipple. |
|
|
How is milk expelled from the alveoli?
What hormone triggers this expulsion? |
Myometrium surrounds each alveoli and contracts to secrete milk.
OXYTOCIN triggers this contraction. |
|
|
What is secreted in milk?
|
~4% enveloped lipid droplets
other membrane-bound contents like proteins, maternal antibodies as well. |
|
|
Adipose tissue is more prevalent in YOUNGER OR OLDER WOMEN?
|
YOUNGER!
With aging, adipose tissues are replaced with connective tissue. |
|
|
What cell types do you expect to find in alveoli?
|
Cuboidal or low columnar epithelial cells.
|
