Abdominal Muscles
Functional Anatomy: Muscle and Isolated Function
Muscle | Isolated Function |
---|---|
Rectus Abdominis | Concentrically accelerates spinal flexion, lateral flexion, and rotation |
External Oblique | Concentrically accelerates spinal flexion, lateral flexion, and contralateral rotation |
Internal Oblique | Concentrically accelerates spinal flexion, lateral ipsilateral rotation |
Tranversus Abdominis | Increases intra-abdominal pressure Supports the abdominal viscera |
Diaphragm | Concentrically pulls the central tendon inferiorly increasing the volume in the thoracic cavity |
