quiz #3 - reproductive system Flashcards
3 phases of menstruation
- follicular
- ovulation
- luteal
causes of dysmenorrhea (menstrual cramps)
endometriosis, uterine fibroids, pelvic inflammatory disease, unknown cause
causes of pelvic inflammatory disease (PID)
bacteria from STIs: most common = chlamydia, gonorrhea
or infection spread from appendix, or bacterial spread through vagina & cervix
causes of uterine prolapse
progressive relaxation/ weakening of pelvic support structure
aging, pregnancy, obesity, vaginal births, short intervals between pregnancies, birth of large child
causes of ovarian cysts
related to menstrual cycle & hormonal abnormalities (excess androgens)
certain diseases: Cushing’s syndrome, acromegaly, obesity, diabetes, thyroid disease, lipid & cholesterol disorders, genetics/ familial tendency
causes of vaginal candidiasis
yeast-like fungus called Candida albicans
causes of cervical cancer
70-90% caused by viruses like human papilloma virus (HPV), herpes simplex type 2 & HIV
– also linked to history of STIs: chlamydia, gonorrhea & syphilis – transmitted by sexual intercourse & caused by viruses
causes of a miscarriage
mostly by chromosomal abnormalities (50%)
drug & alcohol abuse, exposure to environmental toxins, hormonal irregularities, infection, obesity, physical abnormality with reproductive organs (incompetent cervix), ectopic pregnancy, immune response, serious body-wide diseases in mother like diabetes – 50% of all fertilized eggs die this way, often before pregnancy is known
fluid-filled sacs form in ovary due to hormonal changes
2 types:
– follicular/functional cysts: from follicle
– corpus luteum cysts: from ruptured follicle that eventually forms corpus luteum
ovarian cyst
endometrial tissue grows outside uterus & responds to hormones causing pain & inflammation, eventually scarring
endometriosis
classic triad of symptoms for endometriosis
painful menstruation (dysmenorrhea)
painful intercourse (dyspareunia)
infertility or difficulty in conceiving
- pain may also occur during urination (dysuria) or defecation (dyschezia)
benign tumors (leiomyomas) in uterus that are composed largely of smooth mm & fibrous tissue, appear only during childbearing years
uterine fibroids
malignant tumour in one or both ovaries
ovarian cancer
malignancy of uterus, most common gynecologic cancer – usually diagnosed in postmenopausal women – many cases detected early as abnormal vaginal bleeding, which is a common sign of …
uterine cancer
premature detachment of placenta from uterine wall before fetal delivery causing hemorrhage in mother & reduced oxygen/ blood supply to baby
placenta abruption
inflammatory condition of any or all organs of female reproductive tract, may include cervix, endometrium, fallopian tubes, ovaries, vagina & peritoneum
pelvic inflammatory disease (PID)
implantation of fertilized ovum outside uterine cavity, 95% occur in fallopian tube
-can also been found on ovary, cervix, outer wall of uterus, peritoneal surface of abdominal cavity, in vaginal canal
ectopic pregnancy
spontaneous loss of a fetus before 20th week of pregnancy
miscarriage
rare mass or growth (80% benign) of abnormally fertilized egg & placenta that forms inside uterus at beginning of pregnancy, also called gestational trophoblastic disease (GTD)
hydatidiform mole
fertilized ovum implants in lower segment of uterus & developing placenta grows over internal cervical os, passage between uterus & cervix – puts mother & baby at risk as a result of hemorrhage during 3rd trimester
placenta previa
glucose intolerance that develops in women during pregnancy – prevalence is 2-5% – diagnosed during 2nd trimester → fetal complications include excessive growth, respiratory distress syndrome & premature birth
gestational diabetes
