Which group of bones is found at the top of the spinal column?

The cervical group of bones is indeed located at the top of the spinal column. This region consists of seven vertebrae, designated C1 to C7, which are responsible for supporting the head and allowing a wide range of motion in the neck. The cervical vertebrae play a critical role in protecting the spinal cord, which runs through the vertebral foramen created by the vertebrae.

Additionally, the cervical region facilitates important movements such as rotation, flexion, and extension of the head. The first cervical vertebra, known as the atlas, supports the skull, while the second, the axis, allows for head rotation. This unique configuration distinguishes the cervical vertebrae from the thoracic, lumbar, and coccygeal vertebrae, which have different anatomical features and functions in the spine.
