Flashcards in Oviduct histology Deck (29):
What are the divisions of the oviduct?
How is the intramural segment different from the isthmus and ampulla hisotologically?
No folds (almost)
What is outside the mucosa in the oviduct?
When does tubular peristalsis occur?
What are the anatomic divisions of the uterus?
What are the layers of the uterus?
What is the epithelium like in the endometrium?
Simple tubular glands
Simple columnar epithelium with cilia
What are the zones of the endometrium?
What is the role of the basal layer?
Not shed during menstruation
Regenerates functional layer
What are the two layers within the functional layer?
Superficial compact layer
Deep spongy layer
What changes do the smooth myocytes undergo during pregnancy?
Where does the blood supply come from for the endometrium?
Spiral arteries/Straight arteries
What are the five phases to the menstrual cycle?
What is the predominant hormone in the proliferative phase?
What is the predominant hormone in the secretory phase?
What layer thickens in the proliferative phase?
What do cells accumulate in the proliferative phase?
What phase is characterized by glandular growth, the further accumulation of glycogen, and elongation of coiled arteries?
What do glands look like on cross section during the secretory phase?
What happens during the premenstrual phase?
Constriction of coiled arteries in response to decreased progesterone
Anoxia induced tissue necrosis
What happens in them menstrual phase?
Functional layer of endometrium undergoes complete necrosis and is shed
Why does the blood not clot in the menstrual phase?
Presence of fibrolysin
What is the mucosa like for the cervix?
Branching cervical glands
What hormones makes cervical secretion less viscous?
Where is the transition to stratified squamous epithelium in the uterus?
External cervical os
Where do most precancerous and carcinoma lesions develop?
If the gland ducts become occluded, what pathological structure occurs?
What effect does progesterone have on the cervical mucus?
Retards particle passage
