PSYC 210 1st Edition Lecture 3Outline of Current Lecture I. Why a course in Human Sexuality?II. Socialization and SexualityIII. The Science of SexOutline of Current Lecture I. Female External AnatomyII. Female Internal AnatomyCurrent Lecture- Female external anatomy o Vulva- any part of your private areathat touches your jeans; thecollective term for female partso Labia majora Labia means lips On the outside and arebigger Thicker o Labia minora On the inside and aresmaller More sensitive and thin Covers the vaginal opening Bartholin’s Glands- createlubrication for vaginalpenetrationo Mons Veneris- fatty deposit on thefront, usually covered in pubic hairafter pubertyo Clitoral hood- covers the clitoris Basically where the labia minora meet up at the topo Clitoral glans- (aka the clitoris/clit) Has a shaft Has legs (routes that goes into the body) Is really sensitive to touch, sometimes too sensitiveThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. Made up of the same embryonic tissue as the penis, meaning it can get erect, it is very sensitive to touch and creates pleasureo Vestibular opening- the area containing the vaginal openingo Vestibular bulbs- fill with blood during sex and makes the vagina tightero Bulbocavernasular muscle- a ring of sphincter muscles that surrounds the vaginal opening in women or the root of the penis in men Sexually experienced women can learn to voluntarily contract or relax these muscles during intercourse In sexually inexperienced women, these muscles may involuntarily contract as a result of extreme nervousness, making penetration very difficult Urethral opening- Located below the clitoris and above the vagina opening- Only visible when the labia minora are parted o Vaginal opening is very sensitive to touch, but the walls of the inner 2/3rds are relativelyinsensitive to touch as a result of having few nerve endingso Hymen- tissue that covers the vaginal opening Most women are born with one Has small holes in them to allow for menstruation  Has historicallybeen seen as atest for virginityo Perineum- pelvic flooro Anus - Female internal anatomy o Suspensory ligamento Medulla o Cortex of ovaryo Ovarian ligamento Fallopian tube- how eggsreach the uteruso Ovary- produces eggs andreleases them into theuterus Regulates themenstrual cycle o Fimbria- finger likestructures that hang off thefallopian tube to catch theeggso Ovarian vesselso Uterus Promethium- the outside layer Myometrium- the muscle that can push babies out; the muscle that contracts Endometrium- the innermost layer that gets thicker during the menstrual cycle that gets shed off- Where the egg gets implanted- Endometriosis- a disease where this layer grows outside the uterus. Is painful and can threaten fertilityo Broad ligament- the area between the fallopian tube and ovaryo Cervix-  Keeps a lot of stuff out of the uterus and keeps things in (like a baby) The opening is called the os which is the part that protrudes into the vaginao Vaginal wall- basically just a tube that’s typically laying flat G-spot- a highly sensitive area on the front wall about a 1/3 of the way in that supposed to be a highly sensitive area Seems to exist in 10% of women The vagina is self cleaning (the vulva is not!) the more you mess with it, the nastier it gets.  Designed for having sexual activity, it can clean it up. o Kegel exercises help with the muscle strengthso Youtube.com/watch?v=toKp0SGyv5wo Ovulation A follicle is released from the ovary it travels down the fallopian tube to the uterus - Ovarieso Female gonads produce ova (eggs) and hormones (estrogen and progesterone)o At birth, ovaries already contain all of a woman’s 300,000-400,000 immature ovao Only about 400 will ever fully matureo Form primary follicle to Graafian follicle to ovulationo You’re born with all the ova you will ever have only 400 ever become fully matureo Primary follicle is an immature ovao Graafian follicle is a mature ova- Egg travelogueo Ovary (primary follicle)o Ovary (Graafain follicle)o Fimbriao Fallopian tubeo Uterus Endometrium Outside the body- Routine check-upso Pelvic exam (aka vaginal exam) Pap smear- Youtube.com/watch?v=b8tBdHbTXk0&list=PL674C60951924EDD4- Detects abnormal cells that could detect cervical cancer- Does not test for STIs Bimanual exam- Youtube.com/watch?v=dhbOELmVkTc&list=PL674C6095124EDD4o Breast self exam Youtube.com/watch?c=IVSgZ6dvCJg&list=PL5DUVGfj6BJYXxLJxC30m_CfUVPKaU2JJ Do every month on the first of the month (for women without periods) or 1 week after your period  1 in 8 women will develop breast cancer in their lives Males can also get breast cancer If breast cancer is caught early, there’s a 98% chance of
