ARTICULATIONS 5 



extending from the styloid process to angle and posterior 

 border of ramus of the jaw, which is derived from the deep 

 cervical fascia (p. 26). 



(Stylo -hyoid ligament: a fibrous cord extending from the 

 styloid process to small cornu of hyoid bone). 



VI. ARTICULATION OF THE RIBS WITH THE VERTEBRA. 



(a) Articulations between the Heads of the Ribs and the Bodies 

 of the Vertebra. 



Arthrodial joints held together by the following ligaments : 



The anterior costo-vertebral or stellate ligament is com- 

 posed of three fasciculi, which radiate from the anterior surface 

 of the head of the rib. The superior fasciculus passes to the 

 body of the vertebra above ; the inferior fasciculus to the body 

 of the vertebra below ; the middle fasciculus to the interverte- 

 bral substance. 



A capsular ligament surrounds articulation between the 

 head of the rib and the articular surface formed by two 

 vertebrae. 



The interarticular ligament divides the joint into two parts, 

 each of which has a separate synovial membrane. It passes 

 between ridge on head of rib and intervertebral substance. 

 (Absent in the ist, loth, nth, and iath ribs.) 



(b) Articulations of the Necks and Tubercles of the Ribs with 

 the Transverse Processes of the Vertebra. 



Arthrodial joints held together by the following ligaments: 



The anterior or superior costo-transverse ligament passes 

 from the upper border of neck of rib, to lower border of 

 transverse process above. (Absent in ist rib.) 



The middle costo-transverse or interosseous ligament : a 

 short thick band passing from the anterior surface of the 

 transverse process to the posterior surface of neck of corre- 

 sponding rib. (Rudimentary in nth and iath ribs.) 



The posterior costo-transverse ligament passes from apex 

 of transverse process to rough non-articular part of tubercle 

 of rib. (Absent in nth and i2th ribs.) 



The capsular ligament surrounds articular surfaces, en- 

 closing a small synovial membrane. (This articulation is 

 absent in the nth and i2th ribs.) 



VII. ARTICULATION OF THE UPPER SEVEN COSTAL CARTILAGES 

 WITH THE STERNUM. 



The anterior chondro-sternal ligament : a broad thin band, 

 radiating from extremity of the rib cartilage to the sternum.
