Dissection of anterolateral abdominal wall
Nerve supply to external oblique muscle, left lateral view
The fascicles of the external oblique have been separated below their origins from the lower ribs. Lateral cutaneous branches of intercostal nerves which emerge between these fascicles have been dissected. Muscular branches (2,4) from these nerves enter the muscle from its external aspect.
1 . Lateral cutaneous branch thoracic nerve VIII
2 . Upper pointer: Lateral cutaneous branch posterior intercostal artery Lower pointer: Muscular branch of lateral cutaneous branch thoracic nerve IX
3 . External oblique muscle
4 . Upper pointer: Muscular branch of lateral cutaneous branch thoracic nerve X Lower pointer: Muscular branch of lateral cutaneous branch thoracic nerve XI
5 . Aponeurosis external oblique muscle
6 . Umbilicus
7 . Gluteus medius muscle
8 . Latissimus dorsi muscle (partially reflected)
9 . Rib XI (covered by connective tissue)
10 . Thoracolumbar fascia
11 . Iliac crest
12 . Superior cluneal nerves
13 . Gluteus maximus muscle
