Q

This nerve…

  • Splits
  • More superior nerve of the split
  • Travels across the QL and it pierces the transverse abdominal layer
  • Penetrates back wall and gives cutaneous branches
A

Iliohypogastric Nerve (L1)

21
Q

What does the iliohypogastric nerve innervate?

A
  • Skin over iliac crest
  • upper inguinal and hypogastric regions
  • superiolateral quadrant of butt
  • Internal oblique
  • Transverse abdominal muscle
22
Q

This nerve…

  • More inferior to the split
  • Travels closer to the ASIS
  • Travels down the inguinal canal to the testes
A

Ilioinguinal Nerve (L1)

23
Q

What does the ilioinguinal nerve innervate?

A
  • Skin over the lower inguinal region
  • Mons pubis
  • Labia majora
  • Anterior scrotum
  • Adjacent medial thigh
  • Inferior most internal oblique and transverse abdominal muscles
24
Q

This nerve…

-Pierces the psoas major muscle and divides into genital and femoral branches

A

Genitofemoral nerve

25
This nerve... - Goes to the spermatic cord to the cremaster muscle - Goes through the inguinal canal - Goes lateral to enter the canal and then gets into the canal
Genital branch of the genitofemoral nerve
26
This nerve... - Supplies cutaneous innervation to the skin overlying the femoral triangle - Female= anterior labia majora - Male= anterior scrotum and proximal medial thigh
Femoral branch of the genitofemoral nerve
27
This nerve... - Emerges posterior to the psoas and runs on the iliacis toward the lateral part of the inguinal ligament - medial to the ASIS and proximal thigh
Lateral cutaneous nerve of the thigh
28
This nerve... | -Emerges near the lateral border if the psoas
Femoral nerve
29
What does the femoral nerve supplies
- Iliacus - Flexors of the hip - Extensors of the knee - Skin on the anterior thigh
30
This passes over the ala of the sacrum to participate in the sacral plexus
Lumbosacral trunk
31
Typically, how many lumbar paravertebral sympathetic ganglia are there?
4- and they are deep to the psoas major
32
These are the main source of presynaptic sympathetic fibers to the abdominal viscera
-Thoracic splanchnic nerves
33
The greater, lesser, and least splanctnic nerves pierce the crura of the diaphragm and are destined for the... (3)
- Celiac - Superior mesenteric - Aorticorenal ganglia
34
Are the postsynaptic sympathetic neurons that are going to the abdominal wall and lower limbs gray or white rami?
Gray rami
35
Gray rami from intercostal nerves go to...
The abdominal wall
36
Gray rami from the lumbar plexus go to...
Lower limbs
37
The vagus nerves participate in the _______ plexus and emerge as _____
- Esophageal plexus | - Emerge as anterior and posterior vagal trucks
38
Where do the anterior and posterior vagal trunks travel?
-Pass through the esophageal hiatus on the anterior and posterior surfaces on the esophagus and stomach
39
All parasympathetic fibers that are destined for the gut are ______
Presynaptic (the ganglia are located within the walls of the target organs)
40
Where does the abdominal aorta begin and end?
- The aortic hiatus (around T12) | - Ends by dividing into left and right common iliac arteries (L4)
41
This branch supplies the foregut
Celiac trunk
42
This branch supplies the midgut
Superior mesenteric artery
43
This branch supplies the hindgut
Inferior mesenteric artery
44
This can be thought of as a very small continuation of the abdominal aorta
Medial sacral artery
45
Where does the right renal vein and the right gonadal vein drain into?
The IVC
46
What does the IVC pass through in the diaphragm?
The caval hiatus
47
These 2 arteries serve the body wall
- Inferior phrenic a | - Lumbar a
48
What sac collects all the lower body lymph of the thoracic duct
Cysterna chili
