Anatomy Final Exam- Female Repro Flashcards
Germinal Epithelium
layer of simple epithelium covering ovary
Mesothelium
covers mesovarium
Tunica Albuginea
white capsule of dense irregular connective tissue deep in germinal epithelium
Ovarian Cortex
ovarian follicles surrounded by dense irregular connective tissue
Ovarian Medulla
deep in ovarian cortex, loosely arranged connective tissue and blood vessels, lymphatic vessels, nerves
Broad Ligament
attaches to ovaries via mesovarium (double layered peritoneum)
Ovarian Ligament
anchors ovaries to uterus
Suspensory Ligament
attaches ovaries to pelvic wall
Hilium
point of entrance and exit for blood vessels and nerves where mesovarium is attached
Granulosa Cells
several layers of surrounding cells later in development
Follicular Cells and Later Granulosa Cells ___ oocyte and _____
nourish, secrete estrogen
Mature Graafian Follicle
large, fluid filled follicle ready to rupture (ovulation)
Corpus Luteum
- remnants of mature follicle after ovulation
- produce progesterone, estrogen, relaxin, and inhibin
Corpus Albicans
degenerated corpus luteum (fibrous scar tissue)
Oogenesis
- begins in utero; primordial germ cells migrate from yolk sac to ovaries where they differentiate into oogonia
- some degenerate after birth while others grow into oocytes and enter prophase meiosis II (pause here until after puberty)
Oogonia
2n stem cells dividing mitotically to produce millions of germ cells
Females start with _____ primary oocytes. ____ are left by puberty and _____ mature and ovulate.
200,000-2,000,000
40,000
400
At Ovulation the Graafian Follicle Splits into…
two haploid cells one larger (ovum) one smaller (second polar body)
4 Ligaments
- Broad Ligaments (paired, uterus to pelvis)
- Uterosacral Ligaments (paired, uterus to sacrum)
- Cardinal (Lateral Cervicle) (pelvic wall to cervix and vagina)
- Round Ligaments (extend from uterus to labia majora)
Uterine Tubes Lie Between…
folds of broad ligaments of uterus
Infundibulum
funnel shaped portion close to ovary open to peritoneal cavity and attaches to uterus (superior lateral angle)
Ampulla of Uterine Tube
widest and longest portion, making up lateral 2/3 of length
Isthmus
medial, short, narrow, thick-walled portion joined to uterus
3 Layers of Uterine Tube
- Mucosa
- Muscularis

Internal Os
cervical canal opening of uterus
External Os

Myometrium
middle layer, made of three layers of smooth muscles
Thickest myometrium is at _____ while the thinnest is at ____
fundus, cervix
Endometrium
- inner layer, vascular
- simple columnar, lamina propria, endometrial glands
Stratum Functionalis
sheds during menstruation
Stratum Basalis
permanent forms new functionalis
Dendritic Cells
in mucosa, antigen-presenting
Mons Pubis
anterior to openings, elevated, adipose, skin hair, cushions pubic symphysis
Labia Majora
adipose, hair, sebaceous glands, sudoriferous (sweat) glands
Labia Minora
medial to labia majora, no hair, no adipose, few sudoriferous glands, many sebacous glands
Prepuce of Clitoris
covers body
Corpora Cavemosa and Glans Clitoris
erectile bodies
Lactiferous Ducts
