SLIDE 6 - Bartholin’s glands - During heightened excitement (orgasm) will increase amount of fluid and it releases prior to orgasm and it helps with lubrication SLIDE 7 - Ischiocavernosus muscle: surround the clitoris and these will contract during sexual arousal in preparation for intercourse - Bulbospongiosus muscle: it tightens and focuses on the vaginal opening; increase clitoral erection; increase erotic sensation of vaginal penetration to the clitoris - The only known function of clitoris and the clitoral hood is pleasure; facilitate reproduction and it takes several times before you can get pregnant - Glans of clitoris: very tiny; erection of the clitoris comes from the glans themselves - If there’s lots of blood vessels, the glans tend to remain soft SLIDE 8 - Reduce sexual pleasure that might occur SLIDE 9 - Review all of this concepts and diagram - What you see from the naked eye, it’s the vaginal opening aka introitus (the act: penetration of the vaginal opening) SLIDE 10 - A covering of the vaginal canal; the membrane allows for expression of itself - Hole in the hymen and that takes it appearance in a certain way - Annular: circular - Septate: - Cribriform: little holes in the hymen - Vaginal opening tend to increase after childbirth SLIDE 11 - Puboccygeus muscle holds everything together and allows contraction to occur; stiffness of the vaginal walls and allows for pleasure for both male and female; in orgasm, can feel these muscles; also prevents the leakage of urine; also possible function is to keep sperm in the vaginal canal - Perenium: between vaginal opening and anus - pH of vaginal canal tend to be acidic - During times of intercourse, sperm does not thrive in acidic - One speculated function of Bartolin gland is to make the vaginal more sperm friendly SLIDE 12 - The internal reproductive tract NOTE: DUE TO POTENTIAL COPYRIGHT INFRINGEMENTS, THE SLIDES HAD BEEN TAKEN OUT BY OWNER. SLIDE 13 - Clitoris: series of muscles and structures - Perimetrium: outer layer of uterus SLIDE 14 - Tube like structure and it’s very elastic because birth is going to occur here - Thin cellular lining on the inside of the vaginal canal; lots of mucous production - Fibroelastic layer (outer) - Intermediate muscle layer - Lots of nerve endings at the vaginal canal - Coitus: another word for sex SLIDE 15 - Healthy bacteria: lactobacilli - If there’s too much bacteria growth, it gets to candidiasis SLIDE 16 - Heightened sexual arousal - If g-spot exist, it’s on the interior wall of the vaginal wall (where the stomach is) - There are glans around the urethra - Para urethral glans - In research, larger paraurethral glans leads to vaginal orgasm (a possibility) - More nerve endings in some women than others SLIDE 17 - cervix: lots of glans that release mucus - What the mucous looks like changes depending on the menstrual cycle - Every month if the female is not pregnant, 5-6 days of release of blood; buildup of uterine lining and there’s a release if there’s no pregnancy - At the end of expulsion, there’s a renew buildup of uterine lining for ~24 days in the cycle - Consistency of the mucous change, because sperm needs to travel - The uterus has 3 layers - The inner layer: endometrium; the layer that sheds when woman has her period and menstrual cramps; some cramps come from ______ - Myometrium: smooth muscle layer; more severe cramps happen from here; contractions and needs to be healthy in order for the endometrium to shed - Perim
