What is the Difference Between Atlas and Axis Vertebrae

What is the Difference Between Atlas and Axis Vertebrae

The main difference between atlas and axis vertebrae is that atlas is the first cervical vertebra, which supports the skull whereas axis is the second cervical vertebra, which forms the pivot upon the atlas. Furthermore, atlas help to hold the head upright while axis allows the head to turn side to side.

Why are Atlas and Axis different from other vertebrae?

The atlas is the first cervical vertebra and articulates with the occiput of the head and the axis (C2). It differs from the other cervical vertebrae in that it has no vertebral body and no spinous process. Instead, the atlas has lateral masses which are connected by an anterior and posterior arch.

What is the function of the atlas and axis?

The atlas and axis support the head on the lower cervical spine while providing for considerable mobility in flexion, extension, rotation and lateral bending. The first two vertebrae also function as conduits for the cervical cord and vertebral arteries.

What is unique about C1 and C2?

The cervical vertebrae known as C1 and C2 form the top of the spine (neck) at the base of the skull. These vertebrae are uniquely shaped and have vertebral foramen (spaces within the bone) which allow the vertebral arteries to reach through to the brain and supply it with blood.

What is another name for C2?

The C2 vertebra, known as the axis vertebra or the epistropheus, is the second-uppermost of the vertebrae making up the backbone and of the seven (7) cervical vertebrae at the top of the spine.

What movement does the atlas and axis allow?

The atlas and axis in particular work with the ligaments to move the neck. 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.

What is another name for C1 and C2?

The C1 and C2 vertebrae are the first two vertebrae of the cervical spine. They are also called the atlas and axis vertebrae.

Does axis have a body?

The axis is composed of a vertebral body, heavy pedicles, laminae, and transverse processes, which serve as attachment points for muscles.

Why is C2 called axis?

C2 (cervical vertebra): C2 is the symbol for the second cervical vertebra, which is also called the axis. It is so-named because the uppermost cervical vertebra (called the atlas) rotates about the odontoid process of the second cervical vertebra. The joint between the axis and atlas is a pivot type of joint.

What is the atlas in your body?

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.

Is cartilage present between Atlas and Axis?

Cartilaginous joints They allow slight movement because of the elastic pads of fibrocartiolage present between the ends of the bones taking part in the joints, e.g. pubic symphysis of pubis. ... Saddle joints This is the type of synovial joints.

Is C2 an axis?

The axis is the second cervical vertebra, commonly called C2.
