25
Where is the cardinal/TRV cervical ligament?
Lateral region cervix + lateral margin uterine corpus (think cervix)
26
Where is the round ligament?
From uterine cornua/horn across the pelvic space from posterior to anterior
27
What does version + flexion refer to in uterine positions?
Version: cervix angle Flexion: uterine body angle
28
Where is the broad ligament?
-Divides true pelvis into anterior + posterior parts -Hardest to see b/c is actually a double fold of peritoneum -Not a true ligament
29
What are the 4 segments of the fallopian tubes?
Intramural - where tube connects to uterus Isthmic - only tube Ampullary - longest + tortuous Infundibulum - finger like + must catch egg from ovary
30
What are the 3 ovarian ligaments?
Ovarian - connects uterus to ovary Infundibulopelvic - connects pelvis to ovary Mesovarium - encases ovary
31
3 parts of pelvic vascular system?
Arteries, veins, lymphatics
32
What artery feeds the pelvic organs?
Internal iliac artery
33
What artery is most important to sonographers in OB imaging?
Uterine artery (comes off internal iliac + enters uterus at cervix)
34
What does the internal iliac artery + external iliac vein do to the ovaries?
Internal: feed ovaries External: drains ovaries
35
How much water to drink for TA exam?
32 oz, 1 hour before
36
Do we need a full bladder for an EV?
No, empty
37
Frequency for TA/TP probe?
2.5-5 MHz
38
Frequency for EV probe?
3-7.5 MHz
39
Uterus length in child + nulliparous adult?
Child: 2.5cm long, 1cm AP Adult: 8cm long, 5.5cm wide, 3cm AP
40
Fallopian tube length?
7-14cm
41
Ovary measurement?
2.5-5cm in length 1.5-3cm in width 0.6-2.2cm AP Volume = 6-9cm^3
42
Where do the right and left ovarian veins drain into?
Right: directly into IVC Left: directly into left renal vein, then IVC
43
What is the bimanual maneuver?
Aid in optimizing EV imaging as the sonographer puts hand on pt's pelvic area + gently applies pressure over site of interest to move bowel out of the way or other organs/structures that are high up in the pelvis into FOW (ex this helps visualize an ovary better)
44
What 2 muscles m/c seen in TRV on pelvic u/s?
-rectus abdominis (from 5,6,7 ribs + xiphoid process to symphysis pubis + pubic crest) -psoas
45
What is linea alba?
Midline separation (space) b/w R/L aspects of rectus abdominis (our 6 pack)
46
Is the rectus abdominus muscle superficial?
Yes, very!
47
Where does psoas originate from?
Lower thoracic + lumbar vertebrae
48
What happens at L5 to the psoas?
Goes more lateral now creating a gutter within the space, the common iliacs run through here
49
What does the iliacus turn into?
Iliopsoas (happens below level of iliac crest)
50
SF of iliopsoas?
Long hypoechoic strip beside uterus + bladder
51
Where is the obturator internus?
-true pelvis -it is triangular -extends posteriorly + medially along sides of true pelvis -hard to see
52
Where is the piriformis?
-true pelvis -from sacrum, goes laterally + inserts on greater trochanter of femur -usually obscured from gas unless bladder very full
53
What muscles make up pelvic floor?
Levator ani
54
Is the anterior or posterior bladder wall composed of the trigone region?
Posterior (orifices of 2 ureters + urethra)
55
What layers of bladder can we see?
-inner mucosa -thick middle muscularis
56
Vag length?
7-10cm long
57
What is a vaginal fornice?
Little lip/ring in the vagina where the cervix is. The posterior fornix is deeper than the anterior fornix. Spaces normally collapsed.
58
Cervix length?
2-3cm long
59
What does the endocervical mucosa do?
Prevents upward migration of bacteria from vag into uterus (forms mucous plug in pregnancy which seals the uterus)
60
Which endo layer sheds?
Functionalis (NOT basalis)
61
Names of the superficial + deep layer of endo?
Superficial: functionalis that sheds Deep: basalis does not shed
62
Location of ovarian ligs?
Ovarian: from uterus to inferior pole ovary (connects uterus to ovary) Infundibulopelvic: brim of pelvis to lateral pole ovary (connects pelvis to ovary) Mesovarium: double layer peritoneum from posterior surface of broad lig (encases ovary)
63
3 locations ovaries could be?
-posterior cul de sasc -adnexa -above or behind fundus of uterus
64
Space of Retzius location?
B/w bladder + sym pubis
65
Anterior cul de sac location?
B/w bladder + uterus
66
Posterior cul de sac location?
B/w sigmoid colon/rectum + uterus
67
Where does the external iliac go?
Out of pelvis
68
Primary blood supply for uterus, vag, bladder + muscles of pelvic floor?
Internal iliac artery (feeds pelvic organs)
69
Where does the ovarian artery arise from?
Aorta
70
What does the ovarian artery connect with?
Uterine artery, they provide a fail safe blood supply (so that if ovary can't get blood supply from ovarian artery it has another way to get blood so it doesn't die)
71
Where does uterine artery arise from?
Internal iliac artery
72
Does IVC bifurcate above or below level of AO bif?
Slightly below AO BIF
73
What do the external + internal iliac veins do?
External: drain legs Internal: drain pelvic organs + muscles
74
What is a plexus?
Fabric of veins that cover an area or organ
