| Question | Answer |
|---|---|
| ORIGIN OF INTERCOSTAL MUSCLES | BETWEEN ADJACENT RIBS |
| INSERTION OF INTERCOSTAL MUSCLES | BETWEEN ADJACENT RIBS |
| ACTION INTERCOSTAL MUSCLES | ELEVATE RIBS IN INSPIRATION AND MAINTAINS INTERCOSTAL SPACES |
| INNERVATION OF INTERCOSTAL SPACES | INTERCOSTAL NERVES |
| LOCATION OF EXTERNAL INTERCOSTAL | EXTERIOR SURFACE OF RIBS |
| LOCATION OF INTERNAL INTERCOSTAL | INTERIOR SURFACE OF RIBS |
| LOCATION OF INNERMOST INTERCOSTALS | DEEP TO INTERNAL INTERCOSTAL |
| THE INTERCOSTAL MUSCLES ARE THE CONTINUATION OF WHAT TWO MUSCLES | THE EXTERNAL AND INTERNAL OBLIQUE MUSCLES |
| INTERCOSTAL NERVES ARE THE OF THE NERVES | ANTERIOR RAMI OF THE THORACIC SPINAL NERVES |
| ORIGIN OF RECTUS ABDOMINUS | PUBIC SYMPHYSIS AND CREST |
| INSERTION OF RECTUS ABDOMINUS | COSTAL CARTILAGES OF RIBS 5,6,7 AND XYPHOID PROCESS |
| ACTION OF RECTUS ABDOMINUS | FLEXION OF TRUNK AND SUPPORTS COMPRESSION OF ABDOMINAL CONTENTS |
| INNERVATION OF RECTUS ABDOMINUS | VENTRAL RAMI OF INTERCOSTAL NERVES T7-12 |
| THIS MUSCLE CONTRACTS STRONGLY WHILE DOING SITUPS OR LIFTING BOTH LEGS SEVERAL INCHES FROM FLOOR IN SUPINE POSITION | RECTUS ABDOMINUS |
| VENTRAL MIDLINE FIBROUS BAND EXTENDING FROM XYPHOID PROCESS TO THE PUBIS AND IS MIDLINE UNION OF THE APONEUROTIC SHEATHS WHICH COVER THE AB MUSCLES | LINEA ALBA |
| SMALL TRIANGULAR MUSCLE LOCATED AT INFERIOR END OF THE RECTUS ABDOMINUS-PRESENT IN MOST PEOPLE | PYRAMIDALIS |
| CONTRACTION OF THIS MUSCLE PUTS TRACTION ON LINEA ALBA | PYRAMIDALIS |
| ORIGIN OF EXTERNAL OBLIQUE | LOWER 8 RIBS |
| INSERTION OF EXTERNAL OBLIQUE | LINEA ALBA, PUBIS, ANTERIOR ILIAC CREST |
| ACTION OF EXTERNAL OBLIQUE | FLEXION OF TRUNK AND COMPRESSION OF ABDOMINAL CONTENTS-UNILATERALLY IS LATERAL FLEXION AND ROTATION TO OPPOSITE SIDE |
| INNERVATION OF EXTERNAL OBLIQUE | VENTRAL RAMI OF INTERCOSTAL NERVES T7-12 AND L1 |
| LI= | ILIOHYPOGASTRIC NERVE AND ILIOINGUINAL NERVE |
