描述

The lumbar vertebrae are different from thoracic vertebrae:

  • longer size than thoracic vertebrae
  • more uniform shape to their bodies
  • no costal facet
  • shorter spinous process that is craniodorsally oriented
  • long and flattened transverse processes sometimes termed costal processes
  • flat articular surfaces on their cranial and caudal extremities

The number of lumbar vertebrae differ between species. Here are different vertebral formulae:

  • Dogs: C7 T13 L7 S3 Cd20
  • Horses: C7 T18 L6 S5 Cd15-21
  • Bovine: C7 T13 L6 S5 Cd18-20
  • Ovine: C7 T13 L6-7 S4 Cd16-20
  • Pigs: C7 T14-15 L6 S4 Cd20-23
