Spondylolysis, also known as a pars defect, is a defect or fracture at the pars interarticularis of the vertebral arch. [citation needed]. The nucleus pulposus and the fibers of the anulus fibrosus make up the intervertebral disc. Its concavity is due to the increased pressure exerting on the vertebrae due to a mass. The sacral vertebrae are fused with the lumbar vertebrae, and some thoracic and caudal vertebrae, to form a single structure, the synsacrum, which is thus of greater relative length than the sacrum of mammals. Developmental constraints, Hox genes, and cancer", 10.1002/(SICI)1097-010X(19990415)285:1<19::AID-JEZ3>3.0.CO;2-Z, https://en.wikipedia.org/w/index.php?title=Vertebral_column&oldid=999042329, Wikipedia introduction cleanup from September 2019, Articles covered by WikiProject Wikify from September 2019, All articles covered by WikiProject Wikify, Articles with unsourced statements from December 2020, Articles lacking reliable references from February 2019, Articles with unsourced statements from January 2011, Creative Commons Attribution-ShareAlike License, This page was last edited on 8 January 2021, at 06:00.
