Verified step by step guidance

Begin by understanding the structure of the vertebral column, which is a key component of the axial skeleton in human anatomy.

The vertebral column is divided into distinct regions, each with a specific number of vertebrae and unique characteristics.

Identify the five regions of the vertebral column: cervical, thoracic, lumbar, sacral, and coccygeal.

The cervical region consists of 7 vertebrae, the thoracic region has 12 vertebrae, the lumbar region contains 5 vertebrae, the sacral region is composed of 5 fused vertebrae, and the coccygeal region typically has 4 fused vertebrae.

Recognize that these five regions collectively contribute to the flexibility and support of the vertebral column, allowing for a range of movements and protection of the spinal cord.
