Flashcards in 10/7 Anatomy of retroperitoneal space Deck (47):
1

The mesethelium lining the wall of the abdomen

the parietal peritoneum

2

the double layer of paratanium that comes and surrounds the organs

the mesentary

3

the organs of the retroparatanium

acronym SAD PUCKER
suprarenal glands
Aorta/IVC
Duodenum (2-4)
Pancreas (head, neck and body)
Ureters
Colon
Kidney's
Esophagus
Rectum

4

what are the characteristics of the retroparatanial organs.

have paratanium if they are not suspended by mesentary;
have only paratanium on the anterior surface
they lie betwee the paratanium and the posterier abdominal wall

5

suprarenal glands also...

Adrenal glands

6

the outside of the adrenal gland

adrenal cortex

7

the embriological derivation of the adrenal cortex

intermediate mesoderm

8

Gland found in the base of the brain

pituitary gland

9

the layers of the adrenal cortex

(from outside in) Zona glomerulosa; Zona fisiculata; Zona reticularis

10

secrete mineral corticoids like aldosterone to help regulate blood pressure

zona glomerulosa

11

secretes glutocoids like cortisol

Zona fisiculata

12

Secrete antrigens like DHA

zona reticularis

13

the middle section of the adrenal gland

the adrenal medulla

14

what is the derivation of the adrenal medula (embrio)

nural crest cells -- they are really post-ganglionic sympathetic neuronal cell bodies

15

what does the medulla secrete

epinephrin or adrenilin or nor epinephrin

16

Innervation of the adrenal medulla

the T12 level, through the ventral root and ramus, through the lesser splecnic to the corticol renal pre-ganglionic ganglion (don't synapse) then to the adrenal medulla and then synapse to cause hormone release

17

where is the aorta usually

just to the left of the midline

18

the unpaired branches of the Aorta

celiac trunk (for-gut)
superior mesentaric artery (mid gut)
inferior mesentaric artery (hind gut)

19

paired branches of the aorta

inferior phrenic
Renal arteries
gonadal arteries (inguinal canal in men)
lumbar arteries (like the intercostal, supply seg. the lowar back)
common iliac arteries (branch to the external illiac and the internal illiac arteries)

20

where is the inferior phrenic arteries

just below the diaphram

21

go through the inguinal ring and become the femeral arteries

external iliac arteries

22

suply the pelvus and peritonium

internal iliac arteries

23

what are the branches of the IVC

inferior phrenic
Hepatic veins (drain the liver)
renal veins (drain the kidney)
right gonadal vein
left gonadal vein (drains into the left renal vein!)
Lumbar veins (seg. for the lumbar)
ascending lumbar veins (go to the azogous system)
common illiac veins
interior and exterior iliacs

24

tubular organs that drain the urine from the kidneys to the bladder

ureters

25

what part of the colon is retro-paratanial

Ascending colon
the descending colon
the rectum

26

two organs that are considered infra paratanium

Uterus and the bladder (below the paratanium)

27

3 opens in the diaphram

T12 -- Aorta
T10-- Esophagus
T8 -- IVC

28

Muscle from the L1-L5 vetebra level to the femor

psoas major

29

purpose of the psoas major

Hip flexor and vertebra flexor

30

from the illiac facet to the femer

Illiacus

31

purpose of the illiacus muscle

hip flexor

32

the course of the iliopsoas muscles from

from the L1-L5 and from the Illiac crest under the inguinal ligament into the lesser tracanter and below the ligament they are the same muscle

33

the muscle that is at the very back and middle of the retroparataneal space

quadralus lumborum muscle -- big stabalizer

34

The branches of the the Lumbar Plexus

-Subcostal nerve
-Iliohypogastric nerve
-ilioinguinal nerve
-genitofemoral nerve
-lateral femoral cutaneous nerve
-femoral nerve
-obturator nerve
-lumbosacral trunk

35

Nerves off of the T12 level

Subcostal nerve

36

Subcostal nerve purpose

innervates the body wall muscles and supplies the T12 dermatome

37

nerves off of L1 level

iliohypogstric and ilioinguinal nerve

38

nerves branch off of L1 and L2

Genitofemoral nerve

39

Branch of nerve off of the L2 and L3 level

lateral femoral cutaneous nerve

40

Branch of nerve off of the L2, L3, and L4 levels

The femoral nerve and the Obterator nerve

41

branch of nerve from L4 and L5

the lumbosacral trunk

42

supplies the body wall muscle and the lateral part of the L1 dermatome

iliohypogastric nerve

43

courses through the inguinal canal and and the medial section of the L1 dermatome

ilioinguinal nerve

44

inervates body mall muslce and the thigh just lateral the genitals

genitofemoral nerve

45

supply the lateral surface of the thigh

Lateral femoral cutaneous nerve

46

supply sensory to the medial of the thigh and motor to the quads and sensory to the shin

Femoral nerve

47

through the obtorator foramen and to skin just above the knee and medial and the abuctor muscles
