Abdominal wall muscles
• As a group, the muscles forms anterolateral abdominal wall to contain and
protect the abdominal viscera.
• Bilateral contraction causes abdominal compression enabling forced
exhalation,
force required for defecation, urination, and childbirth.
• Unilateral contraction causes lateral flexion and rotate the vertebral column
at the intervertebral joints.
Examples:
1. Rectus abdominis,
2. External oblique,
3. Internal oblique,
4. Transversus abdominis
