The cervical vertebrae are the seven small bones that make up the neck region of the spine. They are labeled C1 to C7, with C1 being known as the atlas and C2 as the axis. These vertebrae support the head, allow for its movement, and protect the spinal cord. Each cervical vertebra has a unique structure, including a small body and a large vertebral foramen. The cervical vertebrae also have transverse foramina, which allow for the passage of blood vessels to the brain. Together, they play a crucial role in maintaining the flexibility and stability of the neck.
