The first cervical vertebra is called the axis?
Actually, the first cervical vertebra is called the atlas, not the axis. The axis is the second cervical vertebra that forms a pivot joint with the atlas, allowing for rotation of the head from side to side.
Are axis and atlas part of cervical vertebra?
The Atlas is designed to allow a nodding movement, whilst the axis below it has the odontoid peg on it to allow shaking, or rotational movement of the skull.
Which one is the first vertebra of vertebral column?
The first vertebra of the vertebral column is called the atlas. It is named after the Greek titan Atlas who was said to carry the weight of the world on his shoulders, as the atlas supports the weight of the skull.
Where are the atlas and axis bones found?
The atlas and axis bones are found in the neck region of the spine, known as the cervical spine. The atlas bone is the topmost cervical vertebra that holds up the skull, while the axis bone is located just below the atlas and allows for rotational movement of the head.
What is the difference between atlas and axis?
The atlas is the first cervical vertebra (C1) that supports the skull and allows for nodding motions, while the axis is the second cervical vertebra (C2) that allows for rotation of the head. The atlas lacks a vertebral body and instead consists of a ring-like structure, whereas the axis has a prominent tooth-like process called the odontoid process that fits into the atlas for rotation.
Which group of vertebrae includes the atlas and axis?
The atlas and axis are among the cervical vertebrae.
The first cervical vertebra is called the axis?
Actually, the first cervical vertebra is called the atlas, not the axis. The axis is the second cervical vertebra that forms a pivot joint with the atlas, allowing for rotation of the head from side to side.
What bone's articulate with the atlas?
The atlas articulates with the axis. The atlas is the first cervical vertebra and articulates with the skull superiorly, and the axis (the second cervical vertebra) inferiorly. The joint between the atlas and axis, dubbed the atlanto-axial joint, is responsible for the increased range of motion of the skull (turning your head left/right, and nodding up/down).The order of the atlas and axis can be remembered because, beginning from the skull, these two cervical vertebrae are in alphabetical order (aTlas then aXis).
Are axis and atlas part of cervical vertebra?
The Atlas is designed to allow a nodding movement, whilst the axis below it has the odontoid peg on it to allow shaking, or rotational movement of the skull.
What is the function of the atlas and axis?
Articulation of the head.

What permits the flexibility of the vertebral column?
