What is the name of the seven bones that form the top part of the spinal column?

The seven bones that form the top part of the spinal column are known as the cervical vertebrae. This region of the spine consists of seven individual vertebrae, labeled C1 through C7, starting from the base of the skull down to the first thoracic vertebra. The cervical vertebrae play a critical role in supporting the head, protecting the spinal cord, and allowing for a wide range of head and neck movements.

In contrast, the thoracic vertebrae consist of twelve bones located in the upper and mid-back and connect to the ribs. The lumbar vertebrae are five larger bones in the lower back, providing support for the weight of the upper body. Pelvic vertebrae typically refer to bones in the pelvic region, specifically the sacrum and coccyx, which are not part of the spinal column in the same way as the cervical, thoracic, or lumbar vertebrae. Thus, the correct identification of the cervical vertebrae is essential for understanding the anatomy of the spinal column.
