Flashcards in Female Repro Histology Deck (47)
What happens to the ovary at menopause
Reduced function - reduced response to pituitary hormones, reduced hormone production
Which ligaments stabilise the ovary
Ovarian and suspensory ligaments
T/F The follicles are found in the medulla of the ovary
False, they are found in the cortex. Medulla is largely connective tissue and blood vessels
What cells are found in the cortical stroma?
highly cellular connective tissue
scattered smooth muscle cells
Why is there scar tissue at the ovary cortex
scar tissue is made due to ovulation (tear due to oocyte)
What layers are found superficial to the ovarian cortex
single layer of epithelium on the outside, followed by tunica albuginea
What cells surround the primordial oocyte
squamous follicle cells surrounded by common basal lamina (type IV collagen)
T/F Meiosis has already begun in a primordial oocyte
True, it is arrested in the prophase of meiosis 1
T/F zona pellucida sits superficial to the follicle cells
False, they sit between the oocyte and the follicle cells
Which cell matures into granulosa cell?
What's stratum granulosum
multilayered, cuboidal granulosa cells
T/F Theca cells sit superficial to the granulosa cells
Which cells mature into theca cells?
the outer stromal cells
What is the antrum of the secondary oocyte?
it's a fluid filled cavity that surrounds the oocyte
What is the cumulus oophorus
a stalk of granulosa cells that suspend the oocyte in the antrum
What is the corona radiata?
granulosa cell layer surround the oocyte after ovulation
What is the name given to a mature follicle?
How is corpus luteum formed?
after ovulation, stromal, granulosa and thecal cells invade the inner cavity and differentiate into luteal cells, forming the CL
What is involution
atrophy with time
What are the three layers of fallopian tube?
outer serosa, middle smooth muscle muscularis and inner mucosa
Why is the fallopian tube epithelium ciliated?
It can beat the peritoneal fluid and move the oocyte
How is isthmus structurally different to ampulla
it has more smooth muscle and less mucosal lining
How does the oocyte get nutrients when moving down the fallopian tube?
epithelium secrets fluid that provides nutrients
What are the three layers of uterine wall?
How many layers of smooth muscle can be found in the myometrium
three: inner and outer longitudinal muscle, with a middle circular layer
T/F The thickened wall regress after pregnancy
False, the thickened wall is retained after first pregnancy
T/F The entire endometrial is covered by ciliated simple epithelium
False, there are spots of non-ciliated, secretory columnar cells connective to glands
How far does the secretory gland extend in the endometrium
penetrates into lamina propria
What artery supplies the endometrial mucosa
helical arteries from the myometrium
