L2
27
Where do the right and left common iliac veins join to form the IVC?
L5
28
The IVC and the aorta lie on which sides of the body?
IVC: Right side, Aorta: left side
29
Symptoms of nutcracker syndrome
Left flank pain, hematuria, left testicular pain or LLQ pain (female), can have enlargement of the paminiform plexus in the scrotum is far enough along
30
Pathology of nutcracker syndrome
Left renal entrapment between the AA and the SMA, leading to renal hypertension and a rupture of thin-walled veins in the kidney
31
Lymph on the anterior surface of the aorta at the celiac trunk/SMA/IMA, recieves from te abdominal viscera
Preaortic lymph
32
Lymph on the sides of the aorta, receives from lower limbs/pelvis, reproductive organs, kidneys/adrenals, abdominal wall
Para-aortic lymph
33
Saccular dilation formed by the joining of the right and left lumbar lymphatic trunks
Cisterna chyli_is the beginning of the thoracic duct
34
Ventral ramus of T12
Subcostal nerve
35
Major plexus for innervation of pelvis and lower limb
Lumbar plexus
36
Path of illioinguinal nerve
Off of L1, anterior surface of quad lumbo, to iliacus, pierces TA/IO anteriorly to enter the inguinal canal, then thru the superficial inguinal ring (NO deep inguinal ring)
37
Branches of liliohypogastric
Lateral cutaneous (posterolateral gluteal skin) and anterior cutaneous (skin over pubic region)
38
Genitofemoral nerve path
L1/2, pierces psoas, then anterior surface posterior to ureter, divides into genital and femoral
39
Obturator nerve path
L2-L4, medial bordr of psoas major (pelvic brim), runs with common iliac vessels, then thru the obturator foramen into medial compartment of thigh, divides into anterior/posterior obturators
40
Femoral nerve path
L2-L4, lateral border of psoas major (anterior to iliacus), runs along the border between the psoas major/iliacus, passes posterior to the inguinal ligament entering the anterior thigh compartment
41
Branches of the femoral nerve
Cutaneous (medial and intermediate), motor (iliacus, pectineus, sartorius, quad femoris), hip/knee branches
42
Rough vertebral level of kidneys
T12-L3
43
Which kidney is higher?
Left kidny
44
What muscle is next to the right kidney?
Quadratus lumborum, TA
45
Anterior contacts to right kidney
right suprarenal gland, descending part of duodenum, right colic flexure
46
Anterior contacts to left kidney
Left suprarenal gland, pancreas, left colic flexure
47
Anterior to posterior hilar structures
Renal vein, artery, pelvis
48
What surrounds the parenchyma of the kidney?
Fibrous capsule
49
Collection of fat outside of the capsule of the kidney, that is also present in the renal sinus
perirenal fat
50
Fascia that encloses the fat and capsule of the kidney
Renal fascia
51
How are the kidneys attached to the body?
Attached to the diaphragm, but open inferiorly
52
Fat between the renal fascia and peritoneum
PARArenal fat
53
Blood supply to the ureters
Ureteric branches off of the renal arteries
54
Path of ureters
Desecnd anterior to psoas, cross iliac artery anteriorly, over the pelvic brim
55
Shape of right suprarenal gland
Pyramid
56
Shape of left suprarenal gland
Flat and semilunar
57
Blood supply to suprarenal glands
Superior/middle/inferior suprarenal arteries
