Flashcards in Anatomy Deck (20):
1

The external oblique fibres run in the same direction as which other fibres?

The external intercostals

2

Which group of muscles are separated by tendinous intersections?

The rectus abdominus

3

How is the linea alba formed for the following muscles:
-external oblique
-internal oblique
-transverse abdominus

The aponeuroses of the muscles blend together at the midline

4

How is the linea alba formed in the rectus abdominus?

Interweaving of the muscle aponeurosis

5

The inguinal ligament is a continuation of which muscle?

The external oblique

6

Where would you find the ilioinguinal nerve?

In between the internal oblique and the transversus abdominus

7

Where does the superior epigastric artery come from?

The internal thoracic artery

8

Where would you find the superior epigastric artery?

Lie posterior to the rectus abdominus

9

Where does the inferior epigastric artery come from?

The external iliac artery

10

Where do the inferior epigastric arteries lie?

Posterior to the rectus abdominus

11

Blood supply to the anterior abdominal wall?

Superior and inferior epigastric arteries

12

Blood supply to the lateral abdominal wall

Intercostal arteries and subcostal arteries, continuation of the posterior intercostal arteries

13

Layers when opening a lady's tummy for caesarean section?

-skin and fascia
-rectus sheath
-rectus abdominus
-fascia and peritoneum
-bladder
-uterine wall
-amniotic sac

14

Layers incised through for laparotomy?

-skin and fascia
-linea alba
-peritoneum

15

Why might midline incisions not heal very well?

Relatively bloodless = increases chances of wound complications e.g. dehiscence, incisional hernia

16

If you are putting in a lateral port, which artery MUST you avoid?

Inferior epigastric

17

What type of incision could you use for a laparotomy?

Sub-umbilical incision

18

Where is the deep inguinal ring?

Half way between pubic tubercle and ASIS

(inferior epigastric arises just medial to this)

19

Route of the inferior epigastric artery?

emerges just medial to the deep inguinal ring

then passes in a superomedial direction posterior to the rectus abdominis

20

How can you differentiate between the ureter and the uterine artery?

the ureter passes inferior to the artery (“water under the bridge”)
- the ureter will often “vermiculate” when touched
