*Ventrolateral Muscles: flanks and abdominal floor
*Ventrolateral Muscles: flanks and abdominal floor
**All muscles join via aponeuroses in the '''linea alba''' at midline, which runs from the [[Ribs and Sternum - Anatomy & Physiology#Costae|xiphoid process]] to the [[Pelvis - Anatomy & Physiology#Pelvic Girdle|pelvic symphysis]] via the prepubic tendon
**All muscles join via aponeuroses in the '''linea alba''' at midline, which runs from the [[Ribs and Sternum - Anatomy & Physiology#Costae|xiphoid process]] to the [[Pelvis - Anatomy & Physiology#Pelvic Girdle|pelvic symphysis]] via the prepubic tendon, ensheathing the ''rectus abdominus''
**The ''External abdominal oblique'' runs caudoventrally from the lateral surface of the ribs and the lumbar fascia to the linea alba
**The ''Internal abdominal oblique'' runs cranioventrally from the tuber coxae and the thoracolumbar fascia to the linea alba
**The ''Transversus abdominus'' is the deepest muscle of the flank, running dorsoventrally from the inner surface of the last ribs and the transverse processes of the lumbar vertebrae
**The ''Rectus abdominus'' forms a broad band parallel to the linea alba, arising from the ventral costal cartilages and inserting on the prepubic tendon
