Why does the head pivots on the second vertebrae?
The second vertebrae has a dens (meaning tooth) which sticks up into the ring made by the atlas (the first vertebra). The head can pivot with this type of joint. A person can nod the head "no".
When the head is moved from side to side the first vertebra pivots around the?
When the head is moved from side to side, the first vertebra pivots around the second vertebra called the axis. This movement allows for rotation and flexibility of the neck.
Head moved side to side first vertebra pivots around?
These movements refer to rotation of the head around the first cervical vertebra, known as the atlas. This motion is controlled by a joint between the atlas and the axis, allowing for side-to-side movement without involving other vertebrae. Rotation of the head in this way is important for various functions, such as scanning the environment and maintaining balance.
What does the first vertebra pivot around when head moves side to side?
The first cervical vertebra, called the atlas, pivots around the second cervical vertebra, known as the axis, when the head moves from side to side. This unique joint allows for the head's rotational movements.
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.....
When the head is moved from side to side the first vertebra pivots around the what of the second vertebra?

Where is the T1 and T2 on the spinal cord?
T1 and T2 refer to the first and second thoraxic vertebrae. They are the 8th and 9th vertebrae, starting from the top.
What is the type of joint found between the first and second vertebrae of the neck region or the backbone?
The type of joint found between the first and second vertebrae of the neck region, or the backbone, is called the atlantoaxial joint. It allows for rotation and flexion of the neck.
Which cervical vertebrae form the atlantoxial joint?
The atlantoxial joint is formed by the first and second cervical vertebrae, known as the atlas (C1) and axis (C2) respectively. It allows for rotational movement of the head.
What bone feature of the second cervical vertebrae articulates with the first cervical vertebrae?
The odontoid process, also known as the dens, is the bone feature of the second cervical vertebrae that articulates with the first cervical vertebrae. This connection forms the atlantoaxial joint, which allows for rotation of the head.
What is second vertebrae called?
The name of the second vertebrae is called the axis.
What does the first vertebra pivot around when head moves side to side?
The first cervical vertebra, called the atlas, pivots around the second cervical vertebra, known as the axis, when the head moves from side to side. This unique joint allows for the head's rotational movements.
What is the first vertabra?
The first vertebrae is called The Atlas.The second is the Axis, which allows the neck/head to pivot(turn).
What regions of the vertebral column do not contain intervertebral discs?
intervertebral discs are not found in the sacrum and coccyx, where the vertebrae have fused, or between the first and second cervical vertebrae.
