Vertebral columns, also known as spines, are the series of bones that make up the human spine. They are connected to each other by ligaments and muscles, and provide support for the body while allowing for flexibility and movement. The vertebral column is made up of 33 individual bones, which are divided into five sections: cervical, thoracic, lumbar, sacral, and coccygeal. Each section has a different number of vertebrae, with the cervical section having seven, the thoracic twelve, the lumbar five, the sacral five, and the coccygeal four. Together, these bones form the backbone of the human body, providing structure and support for the head, neck, and torso.
