57. Outline of a True Vertebra, lateral view. 



Each true vertebra lias a central opening (Foramen vcrtebrale) 

 and an anterior and posterior semi-arch ; the anterior semi-arch 

 becomes the body of the vertebra, Corpus vertebrae; the posterior 

 semi-arch or arch, Arcus vertebrae, has 7 processes: 3 muscular and 

 4 articular processes. Of the muscular processes there is one spinous 

 process, Processus spinosus, and 2 transverse processes, Processus 

 transversi. Of the articular processes 2 look upwards, Processus artlculares 

 ascendentcs, and 2 downwards, Processus articulares desccndentes. The notches 

 at the place where the arch and body touch, form with the neighbouring 

 vertebrae the inter vertebral foramina, Foramina intervertebralla.
