9. SUMMARY

STRUCTURE OF RIB CAGE : THERE ARE THREE PRIMARY COMPONENTS OF THE THORACIC CAGE:

1. THE STERNUM
2. THE THORACIC VERTEBRAE AND THEIR INTERVERTEBRAL DISCS
3. THE RIBS AND COSTAL CARTILAGES

IMPORTANT JOINTS FOR MOVEMENTS : COSTO VERTEBRAL JOINT : THE ATTACHMENT LOCATION OF THE RIB TO THE VERTEBRAE IS CALLED THE COSTOVERTEBRAL ARTICULATION.

MANUBRIO STERNAL JOINT : THE MANUBRIUM – IS LIKE THE HANDLE OF THE SWORD WITH THE BODY OF THE STERNUM ITS BLADE. IT IS THE SUPERIOR MOST COMPONENT OF THE STERNUM

ACTION OF MUSCLES :

1. DIAPHRAGM :

- ON CONTRACTION DESCENDS INCREASING THE

VERTICAL DIAMETER OF THORAX

2. INTERCOSTALS :

-PREVENTS INTERCOSTAL SPACES BEING DRAWN IN

DURING INSPIRATION AND BULGING OUTWARDS

DURING EXPIRATION

-THEY HELP IN ELEVATION OF RIBS

BUCKET HANDLE MOVEMENT :

BUCKET-

HANDLE IS A

MOVEMENT

OF RIBS THAT

RESULTS IN

CHANGE IN

TRANSVERSE

DIAMETER OF

THE THORAX.

Bucket-handle is a movement of ribs that results in change in transverse diameter of the thorax.[1]

PUMP-

HANDLE IS A

MOVEMENT

OF RIBS THAT

RESULTS IN

CHANGE IN

ANTEROPOSTE

RIOR

DIAMETER OF

THE THORAX.
