The Spine. The spine is straight except for slight anterior curvature 

 in the cervical and lumbar regions. 2 There is hyperostosis of the spinous 

 processes/ especially in the cervical region/ and the tenth, eleventh and 

 twelfth thoracic spines are fused. The supraspinous ligament is ossified 

 at the tenth and eleventh thoracic vertebrae and also elsewhere. All of the 

 thoracic and lumbar interspinous ligaments are ossified. The laminae and 

 articular processes of the tenth, eleventh and twelfth thoracic vertebrae are

fused. The liganienta subflava are not ossified below the second lumbar 

 vertebra. The transverse processes also show exostosis and depressions at 

 the seat of ligamentous insertions. The bodies of the cervical vertebrae do 

 not show much change, but from the second to the eighth thoracic vertebrae 

 the bodies show an increase in their anteroposterior diameter and appear 

 slightly wedge-shaped on account of narrowing of their anterior portion. 

 There is ossification of the intervertebral ligament of the entire spine, 

 moderate in the cervical and lumbar regions, extreme in the thoracic re- 



2 This straightness, however, is artificial and produced in the preparation of the 

 skeleton, as the lateral photograph of the patient shows well marked upper dorsal 

 kyphosis.
