sacral obturator lumbar
33
pelvic splanchnic nerves
motor innervation to viscera of the pelvis parasympathetic, S2,3,4
34
lymphatics of the pelvis - higher up in pelvis where does stuff generally drain to?
external iliac nodes ---> common iliac
35
lymphatics of the pelvis - lower in pelvis/deep perineum structures where does stuff drain to generally
internal iliac ---> common iliac
36
lymphatics of the pelvis - where do gonadal drain to
lumbar
37
transperitoneal spread
disease can penetrate through the peritoneal layer and disseminate into the peritoneal cavity
38
what does the bony pelvis consist of?
2 hip bones sacrum coccyx
39
which muscle fills the iliac fossa?
iliacus
40
what group of muscles attach to ischial tuberosity?
hamstrings
41
pelvic inlet is also known as?
pelvic brim
42
is vagina in pelvis or perineum?
superior part - pelvis inferior part - perineum
43
visceral afferents carrying pain from superior aspect of pelvic organs (touching the peritoneum) run alongside _____ fibres and enter spinal cord between levels ____
sympathetic T11-L2
44
visceral afferents carrying pain from inferior aspect of pelvic organs (NOT touching the peritoneum) run alongside _____ fibres and enter spinal cord between levels ____
parasympathetic S2,3,4
45
what separates pelvis and perineum
levator ani muscle
46
what nerve does most stuff in perineum? what are the nerve routes?
pudendal S2,3,4
47
what spinal level does dural sac end
S2
48
what spinal level is anaesthetic injected into in spinal and epidural anaesthetic?
L3-L4 (L5) region
49
spinal anaesthetic vs epidural anaesthetic
same except for spinal you go through 2 extra layers - dura and arachnoid
50
which is faster acting - epidural or spinal anaesthetic?
spinal (closer to spinal cord and rootlets etc)
51
where does pudendal nerve exit the pelvis
greater sciatic foramen
52
where does pudendal nerve re-enter the pelvis/perineum
lesser sciatic foramen
53
when is pudendal nerve block used (labour)
painful vaginal delivery if about to use instruments e.g. forceps or episiotomy or repairing perineal tears/incisions post delivery
54
1st-4th degree tears
1st degree - skin only 2nd degree - skin and perineal muscles 3rd degree - involves external anal sphincter 4th - goes further into the lining of your anus or bowel.
55
what direction is episiotomy incision made
posterolateral (mediolateral)
56
where do external obliques attach
between lower ribs and iliac crest, pubic tubercle and linea alba
57
which attach to thoracolumbar fascia - external or internal obliques?
internal
58
what does linea alba mean
white line
59
what is the rectus sheath
the covering lying over the rectus abdominus muscles
60
do you have a posterior rectus sheath lower down
nope, only have anterior
61
what is the transversalis fascia layer between?
transversus abdominis and extra peritoneal fat
62
nerve supply to anterolateral abdominal wall - what direction do they enter from?
lateral direction
63
what do the 7th-11th intercostal nerves become?
thoracoabdominal nerves
64
blood supply to anterolateral abdominal wall
anterior abdominal wall: - superior epigastric arteries - inferior epigastric arteries lateral abdominal wall: - intercostal and subcostal arteries
65
in a first pregnancy, when does the uterus come out of the pelvis (and can palpate)
12 weeks
66
fundal height at 20 weeks
umbilicus
67
fundal height at 36 weeks
xyphoid process
68
how is fundal height measured
pubic symphysis up to top of fundus?
69
are the rectus muscles cut in a LSCS
nope, they are just separated from each other is a lateral direction
70
LSCS layers when opening
- skin and fascia - (anterior) rectus sheath - rectus abdominis (separate not cutting) - fascia and peritoneum - retract bladder (bladder might be getting in the way) - uterine wall - amniotic sac
71
Laparotomy layers when opening
- skin and fascia - linea alba - peritoneum
72
Laparotomy layers to stitch closed
- peritoneum & linea alba - fascia - skin
73
laparoscopy - If a lateral port is required, care must be taken to avoid the ______ __________ ________
inferior epigastric artery
74
inferior epigastric artery landmarks
- emerges just medial to the deep inguinal ring - then passes in a superomedial direction posterior to the rectus abdominis
75
what is the inferior epigastric artery a branch of?
external iliac artery
76
what are the 3 layers of the pelvic floor
- pelvic diaphragm - muscles of perineal pouches - perineal membrane
77
what is the deepest layer of the pelvic floor
pelvic diaphragm
78
levator ani forms most of the pelvic _________
diaphragm
79
what 3 muscles make up levator ani?
puborectalis pubococcygeus iliococcygeus
80
levator ani innervation
pudendal nerve and nerve to levator ani
81
bulbourethral glands (aka Cowper's glands) function
produces a pre-ejaculate that cleanses and lubricates the urethra prior to the arrival of the semen.
82
4th degree prolapse
completely outside vagina
83
treatment options for uterine prolapse
- sacrospinous fixation - incontinence surgery (controversial now because of the mesh thing)
