1st Cervical Vertebra - female 3D model

The initial 3D model was derived from computed tomography (CT) scans of a 64-year-old female's cervical vertebrae. Specifically, it represents the first and most superior cervical vertebra, also known as the atlas or C-1 (from Latin 'collum' - neck), which is also the topmost vertebra of the spine. The atlas connects to the occipital bone of the skull and forms a ring shape. Its critical role lies in its connection with the second cervical vertebra (C-2 or axis) to form the atlantoaxial joint, which enables the head to turn in different directions. Uniquely, the atlas lacks a vertebral body. An axial-loading force on the back of the head can cause fractures in the anterior and posterior arches, resulting in a condition called Jefferson's fracture. This 3D model serves as an educational tool to enhance understanding of human anatomy and physiology.
