Contributing to kidney stone

Family
Age (40+)
Male
Dehydration
Diet (protein, sugar, sodium)
Obesity

19

Right kideny vs left kideny

Right is more inferior and more susceptible to injury because less protected

20

11/12 rib to L3

21

Kidneys covered in

22

Suprarenal (adrenal) glands location

Located superior to kidneys

23

Outer cortex vs medulla of adrenal glands

Outer - steroid hormones
Inner - epinephrine/norepinephrine

24

Path of blood through kidneys

Renal ---- segmental ----- interlobar------arcuate-----interlobular------affarent arteriole

25

Semgental arteries divide to what and where to they go

Interlobar that ascend in renal columns to corticomedullary junction

26

Arcuate artery bath

Over base of renal pyramids

27

Interlobular artery path

Ascend to overlying cortex

28

Affarent arterioles supply

Each glomerulus

29

Shape of right and left adrenal glands

Left - semilunar
Right - pyramidal

30

Blood supply of adrenal glands

Inferior phrenic, renal arteries, aorta

31

Venous drainage of adreanl

Left - renal vein
Right - IVC

32

Medulla of adrenal glands innervation

PREganglionic sympathetic synapse to stimulate release of nor and epi

33

Quadratus lumborum and innervation

Immediately lateral to psoas
Stabilizes R12 in inspiration
Laterally flexes the trunk
Ventral rami of T12, L1, L2, L3

34

Psoas major and innvervation

Passes under inguinal ligament
Flexor of the thigh
Ventral rami of L1, L2, L3

35

Iliacus and innervation

Also helps flex hip on the trunk

36

Iliac fascia

37

Fibrous arches of diaphragm

39

Lateral arcuate ligament

Thickening of fascia over quadratus lmborum of transver process of L1 to R12

Both medial and lateral arcuate ligament fibers

Extend up to the central tendon

41

Crura

Arise from lumbar vertebra and ascend to central tendon

42

Where to right and left crus unite and into what?
