Anatomy Flashcards
The external oblique fibres run in the same direction as which other fibres?
The external intercostals
Which group of muscles are separated by tendinous intersections?
The rectus abdominus
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
How is the linea alba formed in the rectus abdominus?
Interweaving of the muscle aponeurosis
The inguinal ligament is a continuation of which muscle?
The external oblique
Where would you find the ilioinguinal nerve?
In between the internal oblique and the transversus abdominus
Where does the superior epigastric artery come from?
The internal thoracic artery
Where would you find the superior epigastric artery?
Lie posterior to the rectus abdominus
Where does the inferior epigastric artery come from?
The external iliac artery
Where do the inferior epigastric arteries lie?
Posterior to the rectus abdominus
Blood supply to the anterior abdominal wall?
Superior and inferior epigastric arteries
Blood supply to the lateral abdominal wall
Intercostal arteries and subcostal arteries, continuation of the posterior intercostal arteries
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
Layers incised through for laparotomy?
- skin and fascia
- linea alba
- peritoneum
Why might midline incisions not heal very well?
Relatively bloodless = increases chances of wound complications e.g. dehiscence, incisional hernia
