The Lumbar Vertebrae

Lumbar Vertebrae

  • Each lumbar vertebra has a large, thick centrum for support of the body.
  • It has a neural spine that projects upwards and forwards.
  • There is a pair of large transverse process that are directed forwards.
  • Above the prezygapophyses lies a pair of processes called metapophyses,
  • Below postzygapophyses lies the anapophyses.
  • Metapophyses and anapophysis serve for attachment pf muscles of the abdomen.
  • In some mammals, there may be another process on lower side of centrum called hypapophysis also for muscle attachment.
