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.
When the head is moved from side to side the first vertebrae pivots around the what of the second vertebrae?
When the head is moved from side to side, the first vertebra (atlas) pivots around the dens (odontoid process) of the second vertebra (axis). This motion allows for the rotation and flexibility of the neck.
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.
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.
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".
What is a type of pivot bone?
A type of pivot bone is the atlas, which is the first cervical vertebra in the spine. It supports the skull and allows for the rotation of the head, enabling nodding and turning motions. The atlas pivots around the axis, or second cervical vertebra, which contributes to the neck's range of motion. This unique structure is essential for head mobility and stability.
The odontoid process is found on the?
A small, toothlike, upward projection from the second vertebra of the neck around which the first vertebra rotates. Meaning it is located on the C2 which is the Axis.
What is second vertebrae called?
The name of the second vertebrae is called the axis.
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 special name are given to 1st and 2nd cervical vertebra?
The first cervical vertebra is called the atlas, after the Greek mythological figure who held up the heavens. The second cervical vertebra is called the axis, as it allows the head to rotate from side to side.
Where is the odontoid process found?
The odontoid process is found on the upper surface of the second vertebra. The odontoid process and together with the first cervical vertebra enables the head to move.
What are the different vertebrae in the back bone?
