Week 3 Lecture 2 : 4/14/2016 ▯ Mons pubis= Mons veneris…. Front boundary of the vulvus. Pubic bone increases in fat and connective tissue and decreases in menopause The back boundary is called the perineum…. Very soft and sensitive runs from the vaginal opening to the anus Perineum is usually cut during childbirth this is called an episiotomy. (Highly controversial) (Happens usually at the end when the head is coming out) During childbirth the Virginia is being stretched to let the babies head that means that the vaginal opening is being stretched when childbirth was taken over by the medical practice (laying on the back) laying on back stresses the perineum Medical practice wanted to sow up the straight cuts over jagged cuts (natural) Less prone to infection IF left alone it wontALWAYS rip and if kept relaxed then it wont need to be cut and less likely to tear Also don’t laying down on back when giving birth Nulliparous= Never having given birth…Once stretched will always be a little larger Medical profession thought they could fix this and add an extra stitch or 2 to make the opening smaller…(Husbands knot) Often to small and would have to go back in and reopen it ▯ Also temperature sensitive On the outside skin…if folds are flipped over, there are sweat and sebaceous glands… Sebaceous glands produce oily secretions; They are involved with water proofing the area. There is fat and specialized erectile tissue in the Labia Majora …. Called the Bulbs of the Vestible ▯ More blood colored (pinker) Meets in the very front Alot of sebaceous glands Inside doesn’t have specialized tissue Venous spaces…veins have widened sections not all narrow and during sexual excitement the veins will engorge with blood 2 to 3X larger than their size usually bluish red ▯ Vaginal opening covered by the Hymen…membrane Hymen always has a hole in it… Never sealed Hymen ▯ -Hymen that is fully closed will have a backup of mistral fluid and serious bacterial issues NEVER want a sealed hymen Hymen will never fully go away or shouldn’t go away other than damage When giving birth the Hyman just stretches Membranes vary a lot women to women…can be extremely thin or thick…Thicker more pain when the hymen membrane is stretched Differences of the amount of blood vessels. ▯ ▯ ▯ - Ducts that are right in side the vagina opening Glands of Bartholin ▯ Glands of Bartholin: probably do have some role in lubrication but is minor ▯ Tub that moves urine to the outside of the body In Female the urethra is shorter (4cm long) Easier to cure a bladder infection for females than males Glands of Bartholin Vagina ▯ \▯ Not a lot of nerve endings…few nerve ending good for childbirth and bad for sex Stimulation is the feeling from the colon and urethra -G-spot: Grafenberg spot: region within the anterior of the wall about 1inch 1 ½ up the vaginal barrel region that contains the para-urethral gland. When this region is stimulated it is highly sensitive. Unfortunately not every woman have this. For some women stimulation will cause for ejaculation through the urethra. These fluids are not urine. Collagen injections called the g-shot, which makes it larger and more sensitive. ▯ All research has been done in the late 1990’s Clitoris □ Total structure first described by Helen O’Connell in 1998 □ Glans or tip very sensitive to touch □ Shaft contains two corpora cavernosa (erectile tissue) □ Crura or legs extend wishbone shaped back along the sides of the urethra and the vagina ▯ Before 1998 it was talked about like a structure that was small that happened to be visible and the glands would be talked about, knew it was on a stalk or stem about 1 in length and knew it increased in size for sexual excitement ▯ Glands, shaft that doesn’t stop, turns backwards, 2 legs that go back in the body that surround the urethra and vagina. Freud had hypothesis: that were pretty similar but not all correct Helen O’Connell= urologist who did the first research on the clitoris in 1998 Clitoris= same tissue and glands as the penis Shaft of the clitoris within the have erectile tissue. 2 tissue types: Corpora Courervnosa= same structure within the penis that causes erection of the penis. ▯ During sexual excitant the clitoris changes in structure The glands are now pulled in making it even more sanative. Vaginal barrel then in turn is tighter Clitoris has no role other than to make sex pleasant Clitoris term has been used since the 1500’s Clitoral legs= crura also crosses over the g-spot or near the g-spot Female Genital Mutilation/Cutting (Female Circumcision) Read the article ▯ - Breasts: Signal of womanhood to the public - Mortified sweat glands that are covered in fat and Muscle - Areola; pigmented part of breast and increases in size in puberty; often has bumps on it these bumps are call the Montgomery Glands Most visible in the post- ovulatory phase due to high levels of progesterone. And will really come into play and functional during breastfeeding and pregnancy. There to Lubricate the breast and antibacterial substances. - Also some glands have hair cells/glands on the areola: mostly noticeable during postovulatory phase. -Areola contains the only smooth muscle: Have no control over the contractions. -Striated/striped Muscle: Long strips that you have voluntary control over: All muscle cells spontaneously contract no matter the type of muscle: smaller an bigger Will only have movement when all cells or a large amount of cells contract together in an organized fashion. Breast ▯ Breast size: fat content and connective tissue. Controlling breast size is usually determined genetically Hard to reduce the size the breasts Same amount of milk producing glands no matter the size of the breast. Mammary glands: structure of them is similar to bunches of grapes The stem ends at the nipple and has a number of openings….more like a shower head (multiple holes and mile sprays out)
