1

Where would you insert a needle for paracentesis?

Lateral to the rectus sheath

2

Why must you insert the needle in paracentesis lateral to the rectus sheath?

To avoid the inferior epigastric vessels

3

Which artery does the inferior epigastric artery arise from?

The external illiac artery (just medial to the deep inguinal ring)

4

What is a condensation?

Double layers of peritoneum that attach organs to each other or to the abdominal wall

5

What attaches the liver to the anterior abdo wall?

Falciform ligament

6

Where does the lesser omentum attach?

Stomach to liver

7

Where does the greater omentum attach?

Stomach to transverse colon

8

How does the greater sac communicate with the lesser sac?

Through the omental foramen

9

What is the other name for the lesser sac?

Omental bursa

10

Where is the portal triad?

Within the free edge of the lesser omentum

11

What are the pouches in the male?

Retrovesical

12

What are the pouches in the female?

Uterovesical
Rectouterine (pouch of douglas)

13

Where do sympathetic nerves leave the spinal cord in to supply the abdominal organs

T5 to L2

14

What happens to sympathetic nerves in the abdomen in the sympathetic chain?

Do not synapse
Enter the abdominopelvic splanchnic nerves

15

Where so sympathetci nerves fibres synapse for the abdo organs?

Prevertebral ganglia which are anterior to the aorta at the exit point of the major branches of the abdo aorta

16

How do the sympathetic nerve fibres reach the abdo organs?

Postsynaptic nerve fibres pass from prevertebral ganglia onto the surface of the artrial branches leaving the aorta.
In the periarterial plexus they 'travel along' the arteries to the organs

17

How is the adrenal gland nerve supply unique?

Thes sympathertic nerves leave the spinal cord in the adominopelvic splanchnic at T10-L1 but they do not synpase at the prevertebral ganglia. Instead they travel along the periarterial plexus and synapse directly onto the organ

18

How do parasympathetic nerve fibres reach the abdo organs?

Cranial nerve X
Travel towards and into the periarterial plexis.
Carried to argans, synsapse in the ganglia

19

Where does the vagus nerve supply up to in the GI tract

Distal end of the transverse colon

20

What supplies the descending colon and anal canal parasympathetically

Pelvic splanchnic nerves (S2, 3, 4)

21

Where do visceral afferents from the foregut enter the spinal cord?

T6, -T9

22

Where do visceral afferents enter the spinal cord from the midgut organs

T8-T12

23

Where do visceral afferents from teh hingut organs enter the spinal cord?

T10-L2

24

What group of nerves supplies the body wall of the abdomen?

Thoracoabdominal nerves

25

How do the thoracoabdominal nerves arise?

7th to 11th intercostal nerves travel anteriorly and then their terminal branches leave the intercostal spaces between the internal oblique and transversus abdominus

26

Name the three thoracoabdominal nerves

Subcostal (T12)
Iliohypogastric (L1 first half)
Ilioinguinal (L1 second half)
All anterior ramuses

27

What is the other name for jaundice?

Icterus

28

Where does the breakdown of redblood cells occur?

Spleen

29

What is in the portal triad?

Common bile duct
Hepatic artery
Hepatic portal vein

30

Which ribs could result in piercing the sleen?

Ribs 9-11
