Describe the Lumen, Folds, Cell types and muscularis found in the Infundibulum/Ampulla region of the Oviduct.
|
Wide Lumen
Numerous Mucosal folds Ciliated cells (simple columnar) Thin muscularis |
|
|
Describe the Lumen, Folds, Cell types and muscularis found in the Isthmus/Junctura region of the Oviduct.
|
Narrow Lumen
Few mucosal folds Secretory cells Thick muscularis |
|
|
What is the role of ciliated cells of the oviduct?
|
Transport ovum from ovary to ampulla
|
|
|
Where is the site of fertilization?
|
Ampulla of oviduct
|
|
|
What is the role of the non-ciliated cells of the oviduct?
|
To nourish and support cleaving ovum
|
|
|
What happens to secretory epithelial cells of the oviduct under progesterone influence?
|
Peg Cells: They become smaller with apical nuclear bulges.
|
|
|
What is the inner layer of the uterus called?
|
Endometrium
|
|
|
What is the outer layer of the uterus called?
|
Myometrium
|
|
|
What are the two layers of the Endometrium?
|
Inner Functionalis (sloughed off each cycle)
Outer Basalis (retained each cycle) |
|
|
What are the modified fibroblasts that surround spiral arteries called?
|
pseudodecidual cells
|
|
|
What kind of epithelia is found in the portio vaginalis?
|
The outer portion of the cervix that bulges into the vaginal canal is covered with non-keratinizing stratified squamous epithelium
|
|
|
What do cells of the vaginal epithelium due during the menstrual cycle?
|
thicken and desquamate due to estrogen stimulation
|
|
|
What are the layers of the epithelium lining the vagina and portio vaginalis?
|
from least to most differentiated:
basal parabasal intermediate superficial squamous |
|
|
What would you expect to see on a pap smear under high levels of estrogen?
|
well-developed superficial layer
|
|
|
Pap Smear Day:
1-6 6-14 14-24 24-28 |
1-6: clumped intermediate cells
6-14: Blood disappears, intermediate -> superficial cells 14-24: Numerous intermediate w/ clumping (folded) 24-28: Squamous cell w/ degeneration (dirty) |
|
|

|
|
|
What is unique about a pregnant pap smear?
|
Presence of Navicular Cells (boat shaped, yellow glycogen deposits)
|
|
|
What is unique about menopausal pap smear?
|
"crowded appearance"
