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)
