The Vertebral Column | Anatomy and Physiology I

Learning ObjectivesDescribe each region of the vertebral column and the number of bones in each regionDiscuss the curves of the vertebral column and how these change after birthDescribe a typical vertebra and determine the distinguishing characteristics for vertebrae in each vertebral region and features of the sacrum and the coccyxDefine the structure of an intervertebral discDetermine the location of the ligaments that provide support for the vertebral columnThe vertebral column is also known as the spinal column or spine (Figure1). It consists of a sequence of vertebrae (singular = vertebra), each of which is separated and united by anintervertebral disc. Together, the vertebrae and intervertebral discs form the vertebral column. It is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord, which passes down the back through openings in the vertebrae.Figure1.Vertebral Column. The adult vertebral column consists of 24...
