Anterior abdominal wall

Brachial plexus

The brachial plexus from roots to terminal branches: C5–T1 roots, the upper, middle and lower trunks, anterior and posterior divisions, the lateral, posterior and medial cords, and the nerves each gives off.

DIEP flap

A deep inferior epigastric perforator flap: lower-abdominal skin and fat carried on perforators of the deep inferior epigastric vessels, with the pedicle dissected free of rectus abdominis — the standard autologous breast reconstruction.

Axilla & breast lymphatics

The pyramidal axilla with its walls and contents, the three levels of nodes relative to pectoralis minor, and the long thoracic, thoracodorsal and intercostobrachial nerves at risk in axillary surgery.
