Question 9

Also, what happens here?

lumbar triangle (of Petit). Lumbar hernias can happen here.

Question 10

Answer 13

Iliacus

Question 14

Also name what #1 supplies

Answer 14

1. Lumbar arteries - supply the posterior abdominal wall muscles
2. Abdominal aorta
3. Common iliac as.
4. Median sacral a.
5. Internal iliac as.
6. External iliac as.

Question 15

Name the nerve and which anterior abdominal wall muscle it pierces.

Answer 15

Iliohypogastric nerve - pierces the transversus abdominis muscle

Question 16

Also, what structure does this nerve pass through?

Answer 16

Ilioinguinal nerve - passes through the inguinal canal and out the superficial inguinal ring

Question 17

Also, what does #3 do?

Answer 17

1. Genitofemoral nerve
2. Femoral branch
3. Genital branch - runs in the spermatic cord and supplies the cremaster muscle for motor innervation

Question 18

Answer 18

Femoral nerve

Question 19

Answer 19

ureters

Question 20

Answer 20

Renal veins

Question 21

Answer 21

renal arteries

Question 22

Answer 22

Splenic artery

Question 23

Answer 23

Left adrenal gland

Question 24

Answer 24

1. Testicular vessels - remember the left testicular vein drains into the left renal vein, the right one drains into the IVC.
2. Genitofemoral nerve
3. Ureters
4. Femoral branch of the genitofemoral nerve
5. Genital branch of the genitofemoral nerve
6. Ductus defrens

Question 25

Name deez nerves. Also, what muscle is missing?

Answer 25

1. Iliohypogastric nerve
2. Ilioinguinal nerve
