25
what can the gap in the peritoneum over the oviducts cause
ectopic pregnancy
26
what is the bell like structure at the end of the uterine tube called
infundibulum
27
what are the fingers that surround the infundibulum at the end of the uterine tubes called
fimbriae
28
where does the ovary sit
in the infundibulum
29
what is the ligament attached to the ovary called
ligament of ovary
30
what is the over end of the ligament of ovary attached to
labia majora
31
after the ligament of the ovary has passed through the broad ligament what is it called
round ligament of the uterus
32
what is the position of the uterus
drapped over the bladder usually but not fixed
33
in most women how would you explain the uterus position medically
anteflexed and antiverted
34
what does anteflexion refer to
the long axis of the uterus being flopped forward, on the long axis of the vagina at the internal os
35
what does anteversion refer to
vaginal canal position related to uterus
36
what can happen that is less common to a womens uterus position
retroversion and retroflexion
37
what do retroversion and retroflexion mean
uterus is bent backwards (lies in the retrouterine pouch)
38
3 histological layers of the uterus body
endometrium myometrium perimetrium
39
which is the most internal layer of the uterus body
endometrium
40
which is the muscular layer of the uterus body
myometrium
41
what is the peritoneum covering the uterus layer called
perimetrium
42
what layers can the endometrium be divided into (2)
stratum functionale | stratum basale
43
during the menstrual cycle what is the layer undergoing change
stratum functionale (functional layer)
44
what is the specialised blood supply in the stratum basale of the endometrium
spiral arteries
45
what is also a specialised structure in the endometrium
uterine glands (produce mucus )
46
where is the capillary bed in the endometrium
stratum functionale
47
what does the cervix consist of (2)
external os | fornix
48
what is the external os
the opening into the vaginal canal
49
what is the fornix
the groove around the margin of the external cervix
50
what is a transformational zone
one type of histology to another
51
where is a transformational zone
within the cervix
52
what epithelial covers the first part of the cervix
stratified squamous (same as vaginal) more superficial
53
what does the epithelial lining of the cervix change to further up
simple columnar
54
what can happen at transformational zones
caner (cervical caner here)
55
what are the two main blood supplies to the uterus
aorta branch- ovarian artery | internal iliac
56
what does the ovarian artery supply
ovaries
57
what does the internal iliac supply
everything apart from the ovaries
58
3 branches of the internal iliac
uterine vaginal internal pudendal
59
what do all three branches of the internal iliac have
ipsilateral and contralateral anastomoses
60
what is the difference in the perineal membrane in the females
2 holes --> vagina and urethra
61
what are the female erectile tissues
corpus cavernosus | bulb of the vestible
62
what does the crus region of the corpus cavernous do
attach to the perineum
63
what is the other structure the corpus cavernous attaches to
the glans clitoris
64
difference in bulb of vestibule to corpus spongiosum (in males)
bulb of vestibule present as 2 parts
65
what muscle covers the corpus cavernousus
ischiocavernous muscle
66
what muscle covers the bulb of the vestibule
bulbospongiosus
67
veins=
follow arteries drain into internal pudendal vein
68
what veins are an exception
deep dorsal veins drain into vesicle plexus of bladder
