Anatomy of the thoracolumbar vertebral region

A thorough understanding of the structure and function of the equine verteb ral column can provide a clearer understanding of thoracolumbar spinal diso rders. Three primary functions of the vertebral column include protection o f the spinal cord, support for weight bearing, and flexibility for locomoti on. Osseous structures provide structural support and vary from one vertebr al region to another as functional requirements change. The spinal musculat ure produces complex vertebral movements while the spinal ligaments provide stability to the vertebral column. Proprioception and nociception are two important neurologic functions of the vertebral articulations.
