Question Answer
Function Gametogenesis
Internal/external/both Oviparous -egg Viviparous - birth Ovoviviparous - embryo develops in an egg inside the body
What determine sex in mammals/birds? Sex chromosomes XY/ZZ - Male XX/ZW - Female
Hermaphroditic animals Simultaneous or Sequential
Female genitalia anatomy (11) Ovary fimbriae infundullum ampulla isthmus intramural portion Fundus uterus body cervix vagina
Ovaries Endocrine organs Oestrogen Progesterone
Oogenesis - Stage 1 Primordial follicles. Enclosed by single layer of flattened follicular/granulosa cells and basal lamina. Stimulated at puberty to 1' follices.
Stage 2 - 1' follicles unilayered Oocyte enlargens and fol/gran. cells ^ in size - form cuboidal cells. Oocyte produces Zona Pellucida Glycoproteins important in binding spermatozoa produced
Stage 2 - 1' Follicle multilayered Fol/gran cells ^ number/thicc, become stratified Z.P. assembled
Stage 3 2' follicle Follicular fluid-filled spaces coalesce to form a cavity Granulosa cells start producing oestrogen
Stage 4 - what is formed? Graafian (4') follicle) Antrum produced - large fluid filled cavity
What does C. radiata do? C. radiata surrounds oocyte provides nutrients
What stimulates the proteolytic activity of ovulation? Gonadotropin LH
Where is ovum expelled + picked up? Entrance of uterine tube
How do fimbriae facilitate this process? Vibrate to generate a current
Corpus luteum Endocrine function follicular cells release progesterone
Corpus albicans Ovarian scar of Conn.T. after C.L. degeneration
Where does fertilisation usually occur? Ampulla
Secretory cells of uterine tube epithelia Peg cells watery secretions for gamete nourishment Ciliated Cilia beat rate in response to oestrogen
Cause of ectopic pregnancy Chlamydia trachomantis
Ectopic pregnancy Fertilised egg embeds in uterine tube or peritoneal cavity
Comparative anatomy Simplex - one child Duplex - multiple (rodent) Bicornate (pig) Bipartite (sheep/cow)
Uterine wall anatomy Para peri/visceral peri/peri Endometrium Myometrium
Endometrium (3) epithelial layer Menstrual cycle zygote embeds here
Myometrium (3) Interwoven smooth muscle CT-Hormonal response = hypertrophy/hyperplasia during pregnancy
Diagram Para/peri/myo/endo -> stratum basalis/functionalis
Endocervix Simple columnar cells Crypts mucus secreting cells (oestrogen decreases viscosity)
Ectocervix S.S. Non-K. E
Transformation zone dysplasia - precancerous epithelial changes - associated with HPV
