Which bone is known as atlas?
Atlas The atlas is the first cervical vertebra and articulates with the occiput of the head and the axis (C2). Has no vertebral body and no spinous process. Has lateral masses which are connected by an anterior and posterior arch.
What does the atlas bone do?
The atlas bone (C1) connects your skull to your spine, and with the support of the axis (C2) just below, it gives your head its range of motion. Misalignments in the atlas bone can cause chronic pain, stress, and tension in the head and neck.
Which bone articulates with the atlas?
The atlas articulates superiorly with the occipital condyles found on each side of the foramen magnum of the skull. Inferiorly, it articulates with the second cervical vertebra (C2), which is also known as the axis.
Why is vertebra called Yes bone?

Which bone is known as YES bone?
atlas
The atlas and the occipital bone form the atlanto-occipital joint, which allows neck flexion. When you nod your head as if to say “yes,” that is neck flexion. The atlas and axis form the atlanto-axial joint, which allows head rotation.
Where is your atlas?
Cervical Spine
The Atlas: The Top Bone in Your Cervical Spine The occipital bone rests upon the atlas, the first bone in your neck. The atlas is named after the Greek God Atlas, who held up the world on his shoulders. A pair of synovial joints, known as the atlanto-occipital joint connect the atlas and your skull.
Which joint is called Yes joint?
Along with the atlantoaxial joint, it makes up a group called the craniovertebral joints. The principal movement at the atlantooccipital joint is flexion-extension. This movement permits nodding of the head, as seen when indicating approval (the “yes” movement).
What is an atlas joint?
The atlanto-axial joint is a joint between the atlas bone and the axis bone, which are the first and second cervical vertebrae. It is a pivot joint. There is a pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas.
Which type of joint is present between atlas and axis?
Pivot joint
The joint between the atlas and axis is called Pivot joint. It allows the head to turn from side to side.
