Anatomy of anterior abdominal wall - dissection

00:00 Intro
00:10 Superficial fascia and superficial veins
01:51 External oblique and its aponeurosis
02:47 Internal oblique muscle
03:40 Trasversus abdominis muscle
04:44 The rectus abdominis and rectus sheath
09:00 Arcuate line

Objectives: After completion of this video session it is expected that the students will be able to understand and demonstrate the:
Fascia of the anterolateral abdominal wall:
- Superficial fascia: fatty layer and membranous layer.
- Deep (investing) fascia.
- Endoabdominal fascia.
The linea alba is a strong fibrous raphe where the flat abdominal muscles decussate and interweave.
The flat abdominal muscles:
- External oblique muscle.
- Internal oblique muscle.
- Transverse abdominis muscle.
- Direction of fibers, layers, and the concept of digastric muscles.
The superficial inguinal ring: formation.
Formation and attachments of the inguinal ligament.
The rectus abdominis: attachments and tendinous intersections.
Pyramidalis is a small occasional muscle.
Formation and contents of the rectus sheath.
Formation of the arcuate line.
Location of the neurovascular plane.
Arterial supply of the anterolateral abdominal wall: the anastomosis of the superior and inferior epigastric arteries.
Venous drainage of the anterolateral abdominal wall: Portal hypertension and caput medusae.
To which direction should the rectus muscle be retracted in a paramedian incision?
