Dissection of anterolateral abdominal wall
Nerve supply to external oblique muscle (continued)
The upper fascicles of the left external oblique muscle are shown in this close-up photograph. Nerves (3,4,6,14) which supply the muscle originate from lateral cutaneous branches of the intercostal nerves and enter the muscle from its external surface.
