Document Summary
Axial osteology - bones of the vertebral column. Intervertebral foramen (cranial to caudally) made up of a notch on the caudal side and matches with the cranial aspect of the next vertebrae. Spinal nerves weave in and out comprised of the lamina and pedicle. Allow for the yes and no movements of the head. Dens articulates with the caudal axis and held in place by a transverse ligament. All cervical vertebrae have a transverse foramen except c7. All have costal foveae"s/rib articulations on the thoracic vertebrae. As you progress caudally the spinous processes become shorter. Have neither transverse foramena nor articulations for the ribs. Last pair of ribs is called oating ribs - costal cartilages of this pair end freely. *spinous ligament begins where the nuchal ligament ends. Intercapital ligament connect successive vertebral arch complete roof of vertebral canal punctured when performing spinal tap or epidural injection supports the necks of animals that need to graze.
