What else can I help you with?
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 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 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.
What are the two most superior vertebrae?
The two most superior vertebrae are CERVICAL vertebrae 1 and 2 (C1 and C2). They are also known as the Atlas (C1) and Axis (C2). These two vertebra join together to form the atlantoaxial joint, which helps with the movement of the neck. A structure on the axis called the dens (odontoid process) fits through a foramen (hole) in the atlas to join them together.
What Muscle aids in rotation of axis and atlas?
The sternocleidomastoid pair and the splenius capitus pair act to rotate the head around the joint between the axis and the atlas.The sternocleidomastoid pair and the splenius capitus pair act to rotate the head around the joint between the axis and the atlas.

The backbone in the regions of the neck are?
Cervical vertabrae or axis and atlas
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.
Hard backbone in the region of the neck are the?
Cervical vertabrae or axis and atlas
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.
What is the vertebra of the neck?
The vertebrae in the neck are called cervicle vertebrae. There are 6 of them altogether. The first two (going downward from the skull) are called the atlas and the axis. The rest are just name by their order. Eg: C1 (Atlas), C2 (Axis), C3, C4.....
What is atypical vertebrae of neck?
C1 (Atlas) , and C2 ( Axis ) because they are unlike the rest of the Cervical vertebrae.
What is the pivot joint bone in the neck called?
The pivot joint in the neck the atlantoaxial joint, and it is at C1 and C2. These bones are also called the atlas and the axis.
Which type of joint is your neck joint?
Pivot joint formed between the atlas and the axis (first two vertebrae)

Why is the axis important to humans?
The axis is the second of the seven bones in the cervical spine (neck). The axis, also known as the C2 bone, creates a pivot that allows the C1, or atlas, to turn. It has a tooth like structure that allows the first bone called the atlas to turn. Since the skull actually is held up by the atlas, this joint allows the person to turn their head.
