What else can I help you with?
What type of movement occurs between the atlas and the dens of the axis?
There is rotation of head around the dens of the axis. Dens is actually derived from the body of the atlas vertebra.
The embryonic body of the atlas fuses with the axis and becomes what?
The embryonic body of the atlas fuses with the axis to form the odontoid process or dens. This process helps to stabilize the joint between the atlas and axis, allowing for rotation of the head.
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 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.
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.

Where in the body would you find pivot joints?
The rotation of the atlas on the axis (first two vertebrae)

Which bone helps the rotation of the head?
Rotation of the head occurs between the atlas and the axis bones. These are the first two cervical vertebrae.
Which two bones form the articulation that allows rotation of the head?
Two vertebrae in the cervical section of the vertebral column call the axis and the atlas.
What types of joint movement occurs when a muscle moves a body part around its axis?
rotation
What type of joint movement occurs when a muscle moves a body part around its own axis?
rotation
What type of movement occurs when you turn your head from side to side to say no?
The movement is called rotation, where the head pivots around the axis of the neck to enable movement from side to side. This movement primarily involves the atlas and axis vertebrae at the top of the spine.
Dens here provides a pivot for rotation of the first cervical vertebra?
Atlaswrong . the correct answer is axis (http://en.wikipedia.org/wiki/Axis_(anatomy)) "It forms the pivot upon which the first cervical vertebra (the atlas), which carries the head, rotates."
