THE ARTICULATIONS 



IX. Articulation of the Vertebral Column with the Pelvis. 



The ligaments connecting the last lumbar vertebra with the sacrum are similar 

 to those which connect the segments of the spine with each other viz. : 1. The

 a vertical section of the sternum and cartilages

continuation downward of the anterior and posterior common ligaments. 2. The 

 intervertebral substance connecting the flattened oval surfaces of the two bones 

 and forming an amphiarthrodial joint. 3. Ligamenta subflava, connecting the 

 arch of the last lumbar vertebra with the posterior border of the sacral canal. 

 4. Capsular ligaments connecting the articulating processes and forming a double 

 arthrodia. 5. Inter- and supraspinous ligaments. 



The two proper ligaments connecting the pelvis with the spine are the lumbo- 

 sacral and ilio-lumbar. 



The Lumbo-sacral Ligament (Fig. 164) is a short, thick, triangular fasciculus, 

 which is connected above to the lower and front part of the transverse process
