Insertion By three slips: (1) to vertebra above, 

 (2) to intervertebral disk, and (3) to vertebra 

 below. 

 INTEROSSEOUS. 



Origin Head of rib. 

 Insertion Intervertebral disk. 

 CAPSULAR. 



Origin Neck of rib. 



Insertion Margin of articular surfaces on vertebrae. 



(b) Between the neck of the rib and transverse 



processes. 

 LIGAMENTS : 



ANTERIOR COSTO-TRANSVERSE. 

 Origin Neck of rib. 

 Insertion Transverse process. 

 MIDDLE COSTO-TRANSVERSE. 

 Origin Neck of rib. 

 Insertion Transverse process. 

 POSTERIOR COSTO-TRANSVERSE. 

 Origin Neck of rib. 

 Insertion Transverse process. 

 CAPSULAR. 



Origin Circumference of articular facets. 



LIGAMENTS OF THE STERNUM. 



ANTERIOR : Three ligamentous bands running the entire 



length of the sternum. 

 POSTERIOR : Three ligamentous bands running the entire 



length of the sternum posteriorly. 



COSTO-STERNAL ARTICULATIONS. 



The costo-sternal articulations consist of seven pairs 

 of costal cartilages articulated with the sides of the 

 sternum.
