-contains blood vessels, lymph vessels, and nerves

A

ovarian medulla

25
- receive ovulated oocyte - parts ; 1. infundibulum 2. ampulla 3. isthmus
the uterine tubes
26
distal end of uterine tube | -surrounded by fimbriae
infundibulum
27
middle third of uterine tube | -usualy site of fertilization
ampulla
28
medial third of uterine tube
isthmus
29
- lies anterior to rectum-posterior to bladder - anteverted - fundus - cervix - cervical canal - internal os - external os
anatomy of the uterus
30
usual position of uterus
anteverted
31
rounded superior portion
fundus
32
neck of uterus
cervix
33
opening connecting with uterine cavity
internal os
34
inferior opening of cervix
external os
35
composed of: - perimetrium - myometirum - endometirum
uterine wall
36
serous layer; is the peritoneum | female reproductive system
perimetrium
37
interlacing bundles of smooth muscle | -contracts during childbirth
myometrium
38
mucosal lining of uterine cavity
endometrium
39
-due to hormonal fluctuations in ovaries and uterus
monthly menstrual cycle
40
stimulates production of ovarian follicles and oocytes
ovarian cycle
41
prepares uterine wall for implantation
uterine cycle
42
3 successive phases of female reproductive system
1. follicular phase 2. ovulation 3. luteal phase
43
- series of cyclic phases of endometrium - phasses coordinate with the ovarian cycle - endometrial phases directed by FSH and LH
uterine cycle
44
1. menstrual phase - days 1-5 2. proliferative phase- dys 6-14 3. secretory phase days 15-28
phases of uterine cycle
45
vagina consists of 3 coats
1. adventitia- fibrous connective tissue 2. muscularis- smooth muscle 3. mucosa- marked by transverse folds
46
an incomplete diaphragm
hymen
47
recess formed at the superior part of the vagina
fornix
48
- overlies the pubic symphysis | - pubic hair covers after puberty
mons pubis
49
- homologue of the male scrotom | - encloses the labia minor
labia majora
50
- space between the labia minora | - houses opening to urthra and vagina
vestibule
51
- anterior to vestibule - is erectile tissue - -homologous to the penis
clitoris
52
- anterior boundary- pubic arch - posterior boundary- coccyx - lateral boundaries - ischial tuberosities
female perineum
53
- modified sweat glands - glandular structure ; undeveloped in nonpregnant women - milk production; starts at or after childbirth
breasts
54
- affects 1 of 50k males - commonly from early stage spermatogenic cells - increase of 50% from 1974 to 1990 - cured in 95% of cases
testicular cancer
55
- slow growing - -arises from peripheral glands - risk factors; - fatty diet - genetic predisposition
prostate cancer
56
arises from cells in the germinal epithelium
ovarian cancer
57
arises from the endometrium of the uterus
endometrial cancer
58
- slow growing arises from epithelium at the tip of the cervix - often caused by HPV
Cervical cancer
59
-second most common cause of cancer deaths in women -97% of cases occur in women over 50 treatment; -surgical removal of the mass (lumpectomy) -radiation therapy -administration of selected hormones -chemotherapy
breast cancer
