C1 first cervical vertebra - male 3D model

The 3d model was created from computed tomography scans (CT medical data). It represents the first human cervical vertebra, also called the atlas.

The atlas, often written C-1 (from latin 'collum' - neck), is the most superior cervical vertebra. That being so, it is also the topmost vertebra of the backbone. It is connected to the occipital bone which forms the posterior part of the skull. The vertebra has the form of a ring. Its role is very important because together with C-2 vertebra (also known as the axis) it forms the atloaxoid joint that enables the head to turn in different directions. What’s more, it is different from the rest of cervical vertebrae. The atlas's specific anatomical feature lies in the fact that it has no vertebral body. An axial-loading force on the back of the head can cause the anterior and posterior arches of the vertebra to break. This type of injury is called the Jefferson’s fracture.

Patients's description: male, age 29

The model was created for educational use. Intends to help those interested in human anatomy and physiology during their learning process, as well as encourage other people deepen their knowledge about the human body.
