Q
suprarenal gland
A
endocrine organ
14
Q
secretions of suprarenal gland
A
cortisol aldosterone androgens epinephrine norepinephrine
15
Q
location of suprarenal gland
A
primary retroperitoneal
superior pole of kidney
-between kidney and crura of diaphragm
separrated fro kidney by thin septum
16
Q
shape of right suprarenal gland
A
pyramidal shaped
17
Q
shape of left suprarenal gland
A
crescent shaped
18
Q
cortex of suprarenal gland
A
production of sterods
-glucocorticoids and mineralocorticoids
19
Q
medulla of suprarenal gland
A
postganglionic sympathetic nurons
secretes epinephrine and norepinephrine
20
Q
arterial supply of suprarenal gland
A
superior - inferior phrenic a
middle- aorta
inferior - renal a
21
Q
venous drainage of suprarenal gland
A
suprarenal vein
right directly to IVC
left joined by inferior phrenic vein before draining to IVC
22
Q
lymph drainage of suprarenal glands
A
to lumbar lymph nodes
23
Q
function of diaphragm
A
respiration
contraction - decreases intrathoracic pressure and increases intraabdominal pressure
24
Q
features of diaphragm
A
superior convex, inferior concave
-right and left domes
can reach 5th rib during expiration
25
structure of diaphragm
3 leaves - right, left, central (form central tendon)
| -attached to pericardium via pericardiacphrenic ligament
26
sternal portion of diaphragm
small anterior portion
| -attaches to xiphoid process to central tendon
27
costal portion of diaphragm
largest lateral portion
| -internal surfaces of ribs 7-12 to central tendon
28
lumbar portion of diaphragm
right crus - to LV1-LV3
left crus - to LV1-LV2
right crus forms esophageal hiatus
left is smaller and blends with the right crus
29
median arcuate ligament
tendinous arch between left and right crura
| -forms aortic hiatus
30
level of aortic hiatus
TV12
formed between right and left crus and is bound by the median arcuate ligament
31
medial arcuate ligament
tendinous arch spanning from transverse process of LV1 to 12th rib
arches over quadratus lumborum
32
lumbocostal triangle
area of muscular weakness between costal and lumbar portion of diaphragm
-common site of abdominal viscera to herniate through diaphragm to the thorax
thoroperitoneal membrane
33
caval hiatus
TV8
within central tendon
-transmits inferior vena cava and right phrenic n.
34
esophageal hiatus
at TV10
passes through right crus
-transmits esophagus, anterior/posterior vagal trunks, branches of left gastric artery
35
aortic hiatus
at TV12
passes betwen left and right crus
transmits aorta and thoracic duct
36
motor innervation of diaphragm**
motor - C345 - phrenic nerve
37
sensory innervation of diaphragm**
sensory - phrenic nerve and inferior 6 intercostal nerves
38
phrenic nerve sectioning
paralysis of 1/2 of diaphragm
| -permanent elevation of diaphragm and paradoxical motion during respiration
39
referred pain to diaphragm
C345 - mostly C4 shoulder neck area
phrenic nerve- to C345 dermatomes
thoracic wall - from intercostal nerves
40
arterial supply to diaphragm
superior phrenic arteries from thoracic aorta
inferior phrenic arteries from abdominal aorta
pericardiacophrenic and musculophrenic arteries from internal thoracic artery
41
venous drainage from diaphragm
superior phrenic vein to IVC
pericardiacophrenic veins and musculophrenic to internal thoracic vein
inferior phrenic vein (right to IVC; left merges with suprarenal vein to left renal vein)
42
lymph drainage of diaphragm
superior diaphragmatic (phrenic) nodes - to mediastinal lymph noedes
inferior diaphragmatic vessels - superior diaphragmatic and/or lumbar nodes
43
psoas major attachments
origin - bodies and transverse processes of TV12-LV5 and IV discs
insertion - lesser trochanter
44
action of psoas major
flexion of thigh, flexion of vertebral column
45
innervation of psoas major
ventral rami L1-3
46
attachments of psoas minor
origin - bodies TV12-LV1; IV discs
insertion - iliopectineal eminence
47
action of psoas minor
flexion of vertebral column
48
innervation of psoas minor
ventral rami of L1
49
attachment of iliacus
origin - iliac fossa
insertion - lesser trochanter
50
action of iliacus
flexion of thigh
51
innervatino of iliacus
femoral nerve
52
attachment of quadratus lumborum
origin - iliac crest, iliolumba ligament
insertion - 12th rib, transverse processes of lumbar vertebrae
53
action of quaratus lumborum
extends/side bends vertebral column
| inspiration
54
innervation of quadratus lumborum
ventral rami of T12-L5
55
psoas sign
pain upon extension of thigh
| -can indicate abdominal infection
56
organs on right near psoas?
```
kidney
ureter
cecum
appendix
ascending colon
sacrolilac joint
```
57
organs on left near psoas
```
kidney
ureter
descending colon
sigmoid colon
pancreas
sacroiliac joint
```
58
lumbar plexus
ventral rami of L1-L5
-sensory and motor to abdominal wall, inguinal,
