PregnancyIV. BreastsCurrent LectureI. Test Materiala. Myth/fact/value questionsi. Determine what kind of statement the sentence isii. Also know the different ways values are statedb. Multiple choicec. Equivalency questions (female to male parts and vice versa)d. Fill in the blacke. Short essay questionsf. Bring #2 pencil!g. Chapters 1-4 in the book and lecture materialsII. Menstrual Cyclea. Endometrial lining in uterus changes shape and size during cycleb. 2nd line is where the eggs are produced (ovaries)c. estrogen and progestin are produced in the ovariesd. the endometrial lining and progestin (main hormone that builds up lining of uterus and if its not present causes the lining to snuff off) curvatures are similari. progestin holds the lining in placee. FSH (follicle stimulating hormone) stimulates the egg follicles in the ovariesi. As FSH increases in the ovaries, eggs start to ripenii. 1st mature egg sends signal to stop others from maturingiii. causes estrogen levels to rise, which then cause progestin levels to risef. middle cycle  ovulation  egg matures and leaves ovaryi. LH changes surrounding cells into yellow body in the ovaries, triggered by luteinizing hormone.These 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.ii. Corpus louden lives on its own for about 2 weeks, then disintegrates. (levels of progestin drop)g. INTERUPTIONS:i. Pregnancyii. Menopauseiii. Weight/fat lossiv. Ill/sicknessh. *Note: either ovary can produce egg  they don’t take turnsIII. Pregnancya. Egg leaves ovary with 46 chromosomes b. Zona pellucida protects the egg from attack by bacteriac. More than 1 sperm can penetrate the zonai. When sperm penetrate the zona they lose their tailii. Electrical charge of egg changes when sperm penetrates itd. Egg then still have too many chromosomes (46) so the sperm sits in a pocket and waits for meiotic completion.e. The egg divides and the smaller egg disintegrates; the egg invites the sperms’ DNA to join the mother’s DNA in the fallopian tubef. Egg starts to travel down the tube VERY SLOWLY (4-6 days)g. Egg implants itself into the endometrial lining (about 50% of fertilized eggs don’t make it to this step)i. They then anchor themselves into the lining and send out a drill (which becomes the umbilical cord) into the lining for supplies (i.e., oxygen)h. Every time the egg multiples in number, it still remains the same size.i. Note: ectopic pregnancy can cause the fallopian tube to burstj. Zygote produces HCGi. Hormone keeps corpus ludium aliveii. Produces more progestin  endometrial lining stays in tact (no period)iii. Hormones stay up throughout the entire pregnancyk. *NOTE: transudation  female lubricationIV. Breastsa. The difference in women’s breast size is due to the amount/size of fat cells (mammary glands are the same)b. Breast size is totally uncorrelated to ability to breast feed and how much women enjoy breast stimulation.c. Mammary glands tube network to nipple aread. Milk production doesn’t occur in women until after birthe. High estrogen and progestin levels suddenly drop when a woman’s water breaksf. *Prolactin, colostrum, oxytocing. Feedback mechanism between breast being suckled and milk productioni. When weaned, prolactin stops being produced and milk production stopsh. Oxytocin is produced in large amounts and causes milk to leave the breast. i. Released during orgasm, period, when baby is
