 posed of four ; each has a body 

 and an arch ; latter has two pedi-

Intervertebral articulations, between 

 the bodies — amphiarthrodia. 



Between articular processes — arthro-

Attachment of muscles. — To the Atlas 

 are attached nine pairs: the longus 

 colli, rectus anticus minor, rectus 

 lateralis, rectus posticus minor, ob- 

 liquus superior and inferior, splenius 

 colli, levator anguli scapulae and first

To the Axis are attached eleven pairs : 

 the longus colli, obliquus inferior, 

 rectus posticus major, semispinals 

 colli, multifidus spinae, levator anguli 

 scapulae, splenius colli, scalenus 

 medius, transversalis colli, intertrans- 

 versales, interspinales. 



To the remaining vertebra generally 

 are attached thirty-five pairs and a 

 single muscle: anteriorly, the rectus

 anticus, medius, and posticus, psoas 

 magnus, psoas parvus, quadratus 

 lumborum, diaphragm, obliquus in-
