|
The oviducts (fallopian tubes) are divided into 4 regions:
|
Infundibulum, ampulla, isthmus, and intramural portions.
|
|
|
Which region of the oviduct is the area where fertilization usually occurs?
|
Ampulla
|
|
|
How many layers make up the wall of the oviduct?
|
-Mucosa
-Muscularis -Serosa |
|
|
(Layer 1) Mucosa of the oviduct consist of two cell types: explain.
|
a.) ciliated: have cilia that beat towards uterus and propel liquid forward
b.)non-ciliated (Peg) cells which secrete a viscous liquid in the lumen of the oviducts. This substance is important for capacitation of the sperm. |
|
|
What is the epithelia type of the mucosa?
|
Simple columnar epithelium
|
|
|
(layer 2) Muscularis layer has how many smooth muscle layers?
What does it do? |
Two layers of smooth muscle (inner circular, outer longitudinal).
The contractions of muscularis propels the liquid and oocyte towards the uterus. |
|
|
What are the three regions of the uterus?
|
-Fundus
-Body -Cervix |
|
|
The Body and fundus regions of the uterus are composed of what three layers?
|
-Outer layer: Perimetrium
-Middle layer: Myometrium -Inner layer: Endometrium |
|
|
The fundus of the uterus is surrounded by _________ while the body is surrounded by __________.
|
1.) Serosa
2.) Adventitia |
|
|
A.) Outer layer: perimetrium of the uterus: What is this?
|
This is the outermost layer of the uterus. It is either serosa (Fundus) or adventitia (Body).
|
|
|
This uterine layer makes up the bulk of the uterine wall with three to four poorly defined layers?
|
Middle layer: Myometrium
|
|
|
During pregnancy, this layer grows by both hypertrophy and hyperplasia and is degraded after pregnancy.
|
Middle layer: Myometrium
|
|
|
This is the mucosal lining of the uterus.
|
Endometrium
|
|
|
This uteral layer is the site for implantation.
|
Endometrium
|
|
|
What are the two layers of the endometrium?
|
1.) Stratum Basale: retained at menstruation and regenerates the next lining
2.) Stratum functionale: Sloughed off at menstruation |
|
|
Compare and contrast The straight arteries and Helical "spiral" arteries of the Endometrium.
|
Straight arteries only penetrate into the basal layer and are retained
Helical arteries extend deep into the functional layer and will be broken during menstruation. |
|
|
What artery do straight and helical arteries branch?
|
Arcuate arterty
|
|
|
What are the three phases (and duration) of the menstrual cycle.
|
1.) Mense (1-4 days) necrosis of the functional layer of endometrium
2.) Proliferative/Follicular (5-14) relining of endometrium and renewal of functionalis 3.) Secretory/Luteal (15-28) thickening of the endometrium resulting from glycogen secretions and edema |
