exam 5 Flashcards
breasts are modified
sweat glands
types of tissues in breasts
glandular
stromal
suspensory ligament of breasts
bands of fibrous tissues extending from skin of breats to CT of chest wall
breasts has abundant
blood supply and lymphatic drainage
puberty of breasts
response to estrogen and progesterone
respond to hormonal stimulation
breasts examination
mammogram-identify lesions
benign cystic change in breast
very common
called fibrocystic disease
proliferation of glandular and fibrous tissue
irregualr cyclic response to hormones
fibroadenoma
benign
young women
tumor of fibrous and glandular tissue
breast carcinoma risk factors
family history hormones birth of first child after 30 early menarche late menopause rare in men
breast cancer causes
estrogen-progestin use increase risk of cancer
just estrogen slight increase in risk of cancer
mutant BRCA1 gene
increase breast and ovarian cancer (80%)
mutant BRCA2 gene
breast cancer risk of 80%
classification of breast cancer
site of orgin
presence or absence of invasion
degree of differentiation
evolution of breast cancer
mammogram identify 2 years before exam
cancers may become invasive
metastizes to lymph nodes
early diagnoses
breast cancer treatment
radical masectomy-total masectomy with lymph nodes
partial masectomy-remove parts
lumpectomy-removes tumor
cervicitis
mild chronic inflammation of cervix
caused by std
salpingitis
tubal infection
pelvic inflammatory disease
inflammation of fallopian tubes and ovaries
lower ab pain
increase leukocytes
tubal scarring
condylomas
venereal warts in genital tract
benign tumer like overgrowths
endometriosis
deposits of endometrial tissues outside normal location
remove via laparascopy
synthetic hormones to compress menstrul cycle
cervical polyps
benign arise from cervix
erosion of tip may cause bleeding
cervical dysplasia
abnormal growth and maturation of cervical epitherlium
mild dysplasia of cervix
cervical inflammation
regresses randomly
secere dysplasia of cervix
does not regress
cervical intraepitherlial neoplasia
different stages of abnormalities
some HPV cause this-common
resolve randomly
pap smear shows abnormal cells
benign endometrial hyperplasia
excessive growth
irregular uterine bleeding
benign endometrial polyps
may bleed if tip is eroded
uterine myomas
benign smooth muscle tumors from uterine wall
dysfunktional uterine bleeding
follicle fails to mature and no ovulation
disturbances of hormones
normal uterine cycle
first half- endometrial glands and stroma proliferate under estrogen
midcycle- ovulation
no preggo- corpus luteum sheds and hormone levels fall
primary dysmenorrhea
most common
prostaglandins sysnthesize under influence of progesterone during secertory phase-contractions-pain
ovarian cysts
arise from ovarian follicle that fail to regress normally
funktional cysts
follicle and corpus luteum cysts deranged maturation and involution regress randomly
endometrial cysts
deposits in ovary fill with old blood and debris
benign cystic teratoma
arise from unfertilizes ova that undergo neoplastic change
contains teeth, hair, bone, etc
serous tumor
resembles cells lining fallopian tubes
mucinous tumor
resemblwa mucus secreting tumor of endocervix
endometeroid tumor
resembles endometrial tissue
fibroma
from fibrous CT cells of ovary
toxic shock syndrome
caused by toxin produced by normal flora in reproductive tract
contraception
natural family planning artifical contraception barries methods oral contraceptives IUDs
kidneys produce
urine by filtering blood
ureter
takes urine from kidney to bladder
bladder
stores urine
urethra
takes urine outside of body
3 basic funktions of kidney
excrete wastes of food metabolism
regulate mineral and water balance
produce erythropoietin and renin: hormones
funktional unit of kidney
nephron
glomerulus
bundle of capillaries
surrounded by capsule
mesangial cells
contractile phagocytic cells that hold capillaries together
regulate diameter of capillaries-filteration rate
renal tubule
reabsorbs most of filtrate
secrete unwanted gluid to tubular fluid
PCT and DCT
requirements for normal renal funktion
free flow of blood through capillaries
normally funktioning glomerular filter
normal outflow of urine
renin
released in response to decreased blood volume and low BP, low sodium
angiotensin 2
powerful vasoconstrictor- raise BP
stimulates aldosterone secretion
self regulating
renal agenesis
failure of one or both kidneys to develop
glomerulonephritis
inflammation of glomeruli caused by antigen-antibody reaction
usually follows strep infection
autoantibodies attack basement membrane
nephrotic syndrome
marked loss of proteins in urine-edema low plasma osmotic pressure
arteriolar nephrosclerosis
complication of severe hypertension
renal arterioles undergo thickening-high pressure
gout nephropathy
elevated blood uric acid levels
urate may enter henle loops
UTI
gram negative bacteria
contaminate perianal and genital areas and ascend urethra
