A

Left renal vein udner sma = entrapment syndrome and varicoceles possibles

24
Q

Describe variations in length of renal arteries and veins

A

Right renal arteyr longer
Left renal vein longer = also receives blood from other veins, left gonadal and left suprarenal

25
Q

Describe pelvis

A

Cont with abd wall

26
Q

Describe sacrum

A

5 fused vertebrae

27
Q

Describe hip bones

A

Ilium, ischium and pubic bones - 2 rami, fuse at acetabulum as age- puberty

28
Q

Describe ischial spine

A

Separates 2 sciatic notches

29
Q

Describe iliac crest

A

Where 2 meet = Asis and psis

30
Q

Describe inferior and superior rami

A

Forms obturator foramen

31
Q

Desribe true and false pelvis

A

True =lesser
False = above pelvic inlet, has abd vsicera

32
Q

What forms lateral walls of pelvis

A

Ligaments

33
Q

Describe sacrotuberous ligament

A

Posterior sacrum and coccyx to ischial tuberosity

34
Q

Describe sacrospinous ligament

A

Ischial spine to sacrum

35
Q

Describe greater and lesser sciatic foramina

A

Created by sacrospinous ligament and sacrotuberous ligament - 2 ligaments make notches into foramina

36
Q

Describe ischial spine - what does it make

A

Above = greater sciatic notch
Below = lesser sciatic notch

37
Q

Describe pelvic girdle, Amab and afab

A

Amab = pelvic inlet heart shaped, narrows, smaller, deeper
Afab = 90-100degrees, shallower, wider, circular

38
Q

Describe Sciatic nerve

A

Passes udner prifiormis

39
Q

Describe obturator internus

A

Muscle covers foramen
Also obturator membrane
And tendinitis arch of obturator internus
Leaves pelvic cavity through lesser sciatic foramen

40
Q

What makes up wall of pelvis

A

Obturator internus and piriformis

41
Q

Describe piriformis

A

Anterior aspect sacrum and exits via greater sciatic foramen

42
Q

Describe coccygeus

A

Overlays sacrospinous ligament - on INSIDE

43
Q

What makes up pelvic floor

A

Levator ani = reinforces floor, closes rectum
3 parts = iliococcygeus, pubococcygeus and puborectalis

44
Q

Describe iliococcygeus

A

Ishcial spine and tensions arch obturator internus, inserts here on obturator and when inserts = forms tendinous arch

45
Q

Describe pubococcygeus

A

Pubic —> anterior coccyx

46
Q

Describe puborectalis

A

Around rectum
Pubic bones —> around rectum
Keeps it closed
Relaxes when poop

47
Q

Describe plevic diaphragm

A

Pelvic diaphragm,pelvic membrane and perineal pouch

48
Q

Describe perineal membrane

A

Sheet of fascia = forms pouch between pelvic diaphragm and perineal membrane
Has thin muscles

49

A

Rectum = posterior
Bladder = anterior

51
Q

Describe parts of bladder

A

Apex and base
Median umbilical ligament suspends, at apex of baldder
Detrusor muscle of bladder
Urethra
Ureters

52
Q

Describe urinary trigone

A

2 ureteric orifices - ureters enter, between = interuteric bridge
And internal urethral orifice - urethra exit
No detrusor here

53

I 8 10 EGGS AT 12
= ivc t8, eso t10 and aorta t12
