Vertebral Anatomy and Functions

The video provides an overview of the vertebral column, focusing on the structure of a typical vertebra. It explains the different sections of the vertebral column, including cervical, thoracic, lumbar, sacral, and coccygeal vertebrae. The anatomy of a typical vertebra is detailed, highlighting the vertebral body, vertebral arch, and various processes such as spinous, transverse, and articular processes. The video also covers the vertebral foramen and intervertebral foramen, explaining their roles in protecting the spinal cord and allowing spinal nerves to exit. The video concludes with a summary of the vertebra's structure and a preview of variations in different regions.
