Q

action- rectus abdominus

A

flexes trunk (lumbar vertebrae) and compresses abdominal viscera

  • can acts as an antagonist to the diaphragm
  • stabilizes and controls pelvic lift (antilordosis)

Q

How is the rectus abdominus different above and below the arcuate line?

A

above: internal oblique fascia split contibuting to both anterior sheath fusing with external oblique aponeurosis and posteriorly fusing with transversus abdominus
below: all three aponeuroses pass anteriorly to the rectus and posterior wall is composed of only the transversalis fascia and parietal peritoneum (weaker area and prone to hernias)
