Document Summary
General anatomy: ovary, fimbriae, fallopian tubes, uterus, cervix (of uterus, vagina, clitoris, labia (minor + major) The vagina: mucosa, epithelium: non-keratinized stratified squamous, lamina propria, muscularis: Inner longitudinal muscle: outer circular muscle, adventitia. External genitals (vulva: labia majora, labia minora, hymen, clitoris + prepuce, vaginal orifice. The perineum: urogenital triangle, clitoris, external urethral orifice, vaginal orifice, bulbospongiosus muscle. Ischial tuberosity: anus, external anal sphincter, coccyx. Female reproductive hormones: estrogens, promote development and maintenance of female reproductive structures and secondary sex characteristics. Increase protein anabolism: lower blood cholesterol, stimulates proliferation of stratum basalis to form a new stratum functionalis after menstruation occurs, moderate levels inhibit the release of gnrh, fsh and lh. Hormonal control of ovulation: high levels of estrogens from almost mature follicle stimulate the release of more gnrh and lh, gnrh promotes release of fsh and more lh, lh surge brings about ovulation.
