Q

medial arcuate ligament

Study These Flashcards
A

crura of diaphragm to transverse process of L1

22
Q

lateral arcuate ligament

Study These Flashcards
A

transverse process of L1 to 12th rib

Superior to this ligament lies vertebrocostal triangle

23
Q

Vertebrocostal triangle

Study These Flashcards
A

above lateral arcuate ligament, so thin that it produce herination.

24
Q

apertures of diaphragm

Study These Flashcards
A

inferior vena cava - central tendon T8
esophageal hiatus - anterior/posterior vagal trunks T10
aortic hiatus,thoracic duct, T12

25
arterial supply to diaphragm
thoracic/superior surface of diaphragm is supplied by thoracic aorta, musculophrenic, pericardiophrenic from internal thoracic a. abdominal/inferior surface is supplied by inferior phrenic a from abdominal aorta.
26
Kidney contact area in posterior
1/3 transversaris abdominis 2/3 quadratus lumbarum 3/3 psoas major
27
psoas attachment
transverse processes of lumbar vertebra body and discs of T12-T5 lesser trochanter of femur
28
psoas innervation
ventral branches of lumbar n.
29
iliacus attachment
iliac fossa,iliac crest,anterior sacroiliac ligaments lesser trochanter of femur
30
iliacus innervation
femoral nerve
31
quadratus lumborum
12th rib/lumbar transverse process iliolumbar ligament,internal hip of iliac crest extends/laterally flex vertebral column, fixed 12th rib during inspiration ventral branch of T12, L1-4
32
iliohypogastric n supply
sensory for skin over buttocks, anterior abdominal wall above pubic symphysis. Motor to transversus abdominis, internal oblique m. (pen)
33
ilioinguinal n. supply
sensory - supply groin, scrotum, labia majora | Motor - transversus abdominis, internal oblique m. (pen)
34
genitofemoral n. supply
Genital - cremaster muscle,scrotum in male, labia majora in females Femoral - sensory to skin of femoral triangle
35
lateral femoral cutaneous n. supply
skin over anterior/lateral parts of thigh
36
femoral n. supply
iliacus,anterior compartment of thigh
37
obsturator n.
adductor muscles of thigh
38
celiac plexus
surround celiac artery | innervates stomach, liver, pancreas, gall bladder, spleen, part of duodenum, foregut
39
superior mesenteric plexus
surround superior mesentery a. | duodenum, remaining small intestine, large intestine to peoximal 2/3 of trans. colon, innervates midgut.
40
inferior mesenteric plexus
1/3 of transverse colon, remaining large intestine and rectum, innervates hindgut
41
greater splanchnic n.
T6-9 preganglionic fiber synapse in celiac ganglia -> postganglionic fibers to forgot. Exception pregang go to adrenal medulla. no postgang
42
lesser splanchnic n.
T10-11 | pregang from this synapse in aorticorenal ganglia -> supply kidney
43
least splanchnic n.
T12 pregang terminate in aorticorenal gang and on unnamed gang around kidney within the renal plexus. supply renal a. and ureter
44
Lumbar splanchnic n.
L1,2 Pregang sympathetic synapse in inferior mesenteric gang. all of them sit on abdominal aorta
45
vagus
parasympathetic | supply all abdominal viscera upto and including prooximal 2/3 of transverse colon
46
pelvic splanchninc
S2,3,4 parasympathetic supply inferior mesenteric plexus 1/3 distal transverse colon, remaining large intestine, rectum, pelvic organs
47
referred visceral pain
same segment of spinal cord which received visceral sensory fibers. diaphragm -> dermatome C3,C4,C5 heart -> C8-T5 stomach -> T6-T9
48
visceral lymph nodes
from abdominal viscera drain into nodes situated along unpaired visceral branch of aorta
49
lumbar lymph node
receive drainage from kidney, testes, ovaries, posterior body wall, lower limbs through common iliac lymph nodes. efferent vessel unite to form the right and left lumbar trunks
50
cisterna chyli
visceral lymphnodes, lumbar trunks unite here and form thoracic duct
