The vertebral column, also known as the spinal column or spine, is composed of 26 vertebrae in the human body. These vertebrae are divided into five regions based on their location: cervical, thoracic, lumbar, sacral, and coccygeal. The cervical region consists of seven vertebrae, the thoracic region consists of twelve vertebrae, and the lumbar region consists of five vertebrae. The sacral region consists of one fused bone, the sacrum, and the coccygeal region consists of one fused bone, the coccyx. The vertebral column serves as a protective casing for the spinal cord and also provides structural support for the body.
