Question 1

How are the jejunum and ileum connected to the posterior abdominal wall?

Answer 1

The jejunum and ileum are connected to the posterior abdominal wall through the mesentery.

Question 2

What does the mesentery allow for the jejunum and ileum?

Answer 2

The mesentery allows a great range of mobility for the jejunum and ileum.

Question 3

What is the root of the mesentery?

Answer 3

The root of the mesentery is the line of attachment of the mesentery to the posterior abdominal wall.

Question 4

How does the root of the mesentery run in the abdominal cavity?

Answer 4

It runs obliquely downward from the left to the right at an angle of about 45°.

Question 5

Where does the root of the mesentery begin and end?

Answer 5

It begins at the duodenojejunal junction (L2 level) and terminates at the right sacroiliac joint.

Question 6

What is the length of the root of the mesentery?

Answer 6

The root of the mesentery is 6 inches (15 cm) long.

Question 7

how long is the intestinal border, the depth and the length of the root of the mesentry?

Answer 7

Border: 6m

Depth: 20 cm

Length: 15 cm

Question 8

What does the root of the mesentery cross?

Answer 8

1. 3rd part of the duodenum
2. Aorta
3. inferior vena cava
4. right psoas major muscle
5. right urter
6. right gondal vessels

Question 9

How do you differentiate between the jejnum and illeum?

Answer 9

Generally, the jejunum tends to stay in peritoneal cavity superiorly and to the left, the ileum inferiorly and to the right.

2. The jejunum is wider bored, thicker walled, and redder than the ileum. The jejunal wall is thicker because the permanent foldings of the mucus membrane (plica circulares) are larger, more numerous, and closely set in the jejunum.

Question 10

How many arcades do the jejunum mesenteric vessels typically form?

Answer 10

The jejunum mesenteric vessels typically form only one or two arcades (loops).
