Etymology
The term "Atlas" in anatomy is derived from the mythological character Atlas, who was condemned to hold up the sky for eternity. Similarly, the Atlas vertebra holds up the head.
Structure
The Atlas is a ring-like structure located at the top of the vertebral column. It is unique in its structure as it does not have a body or spinous process. Instead, it consists of an anterior and a posterior arch with two lateral masses.
Function
The Atlas is responsible for the nodding motion of the head, allowing us to signal "yes". It forms the joint connecting the skull and spine and also helps in the rotation of the head.
Related Terms

- Vertebral column: The series of vertebrae that extends from the skull to the coccyx, also known as the spine.
