Histology Of Reproductive Tract Flashcards
What is found in the cortex of ovaries? What about the medulla?
Developing follicles
Neurovascular structures
In which species are the ovarian cortex and medulla the opposite way around?
Horse
What are they functional and non-functional parts of the cortex called?
Parenchyma
Stroma (CT surrounding follicles)
What are the phases of follicular development?
Primordial follicle Primary follicle Secondary follicle Pre antral follicle Antral follicle Mature follicle
Primordial follicles are lined by which epithelium?
Stratified squamous
Primary follicles are lined by what type of epithelial? What is within the primary follicle?
Simple cuboidal epithelium - start to develop theca cells
Dormant oocyte
What type of epithelium lines the secondary follicles? theca cells are still developing. What begins to form around the oocyte/
Stratified cuboidal cells Zone pellucida (thick membrane)
What forms the zone pellucida around the oocyte?
Epithelium of secondary follicle
What forms in the pre antral follicle?
Small cavities
Theca cells still developing
The antral follicle contains what?
Singular antrum (merged cavities)
Developed theca cells
Granulosum cells
After ovulation, which cells are formed? What do these do?
Briefly - corpus haemorrhagicum
Corpus luteum - maintains pregnancy, secretes oestrogen
What is atresia/atric follicles?
Terminal development of follicle
Most never develop, may have remnants of zone pellucida
What are the 3 regions of the Fallopian tube? From medial - lateral
Intramural
Isthmic
Ampulla (convoluted mucosal folds, thick muscle tunic)
What are the 3 laters of the uterus? What are the histological features of these layers?
Endometrium - simple columnar cells
Myometrium - sm. muscle, inner circular, outer longitudinal
Perimetrium - loose CT & lymphatic vessels
The cervix has crypts. What is the function of the cervix?
Seals uterus off during pregnancy, provides stable and sterile environment for the embryo
