infundibulum ampulla isthmus intramural portions Which is the site of normal implantation?? |
ampulla
|
|
|
What is the epithelium of the oviduct? Name them both... and what is the function of each?
|
Simple Columnar- ciliated = Beat towards Uterus
Simple Columnar- non-ciliated (PEG cells) = secretory cells- provide nutrients and capacitation |
|
|
Oviduct - non-ciliated Peg Cells - are most prominant in which phase?
|
Luteal Phase of the menstrual Cycle
|
|
|
Ciliated Simple Columnar cells of the Oviduct assist in transport of the oocyte -
BUT are they required for pregnancy?? NO WHY? because the Oviduct has 2 layer of Muscularis - inner = ??? and outer = ?? |
Oviduct - Muscularis
inner = Circular outer = Longitudinal |
|
|

The outer covering- has 2 different type of layers- Which layer is the site of the implantation of the blastocyst? |
Perimetrium - there are 2 types of coverings one on the body (adventitia) and one on the fundus (serousa)
MYOmetrium is the smooth muscle fibers of the uterine wall - Endometrium is the mucosa lining of uterus- myometrim endometrium |
|
|
Uterus - 3 layers - Perimetrium/myometrium/endometrium
Which layer changes during pregnancy? This is the same layer of the Blastocyst implantation. What type of changes occur? |
Myometrium is the layer for the blastocyst implantation and this is the layer that changes during pregnancy.-
During pregnancy the myometrium does hyperplasia and hypertrophy = increases in collagen fibers!! |
|
|
The myometrium changes during prenancy - how does it look?
