What is the first group of vertebral bones in the skeletal structure known as?

The first group of vertebral bones in the skeletal structure is known as the cervical vertebrae. This group consists of seven vertebrae, labeled C1 to C7, and is located in the neck region of the spine. The cervical vertebrae support the skull, enable head movement, and protect the spinal cord as it travels from the brain through the vertebral column.

The cervical vertebrae are unique in their structure, with features such as a smaller body compared to thoracic and lumbar vertebrae, and transverse foramina, which allow for the passage of vertebral arteries. Their role is crucial not just in supporting the head but also in facilitating various movements like rotation and flexion of the neck. Understanding this anatomical structure is essential for medical professionals, as it is fundamental to bodily movement and neurological function.
