The atlas and dens (or odontoid process) are located in the cervical region of the spine. The atlas is the first cervical vertebra (C1) and supports the skull, allowing for nodding movements. The dens, which is a bony projection, is part of the second cervical vertebra (C2), also known as the axis, and fits into the atlas, enabling rotational movement of the head. Together, they play a crucial role in the mobility and stability of the cervical spine.
What else can I help you with?
Does the dens articulate with the axis?
No
Which feature is unique to the axis?
Dens are unique to the axis.
What two bones articulate with the axis?
The axis, or second cervical vertebra (C2), articulates with two bones: the atlas (C1), which is the first cervical vertebra, and the occipital bone of the skull. The joint between the atlas and axis allows for the rotation of the head, while the connection with the occipital bone facilitates nodding movements.
Where is the axis located on the body?
The Axis is the second vertebra in your spinal column right at the top.
What is a book of maps called?
A book of maps is called an Atlas.A book or collection of maps is called an Atlas, named for the Greek god who jobwas to support the heavens and the earth.A book of maps is an atlas. You can find atlas' online and in your public library.
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.
Which vertebra has a dens?
The axis has a dens, which provides a pivot for the atlas.
What is the dens odontoid process?
Since the dens is part of the Axis vertebra (and project up in the first vertebra, the Atlas vertebra that supports the skull) it is called the Dens Axis
Bone that has the odontoid process?
This is also knows as the Dens.. It is located with the Atlas (c1) and the Axias (c2) it helps with the rotation of the head.
Where did the odontoid process come from developmentally?
The odontoid process, also known as the dens, is derived from the first cervical vertebra (C1), which is called the atlas. During development, the dens of the axis (C2) separates from the atlas and forms as a distinct bony process.
What vertebra has a dens?
2nd cervical vertebra (axis) has dens (also called odontoid process).
Where is the axis bone located?
The axis bone, also known as the second cervical vertebra (C2), is located in the neck, directly beneath the first cervical vertebra (the atlas). It plays a crucial role in allowing the head to rotate, as it has a unique peg-like structure called the odontoid process or dens that fits into the atlas. The axis connects the skull to the spine and is essential for neck mobility.
The axis is the only vertebra with?
The axis is the second cervical vertebra (C2) and has a unique feature called the odontoid process or dens, which projects superiorly from its body. This structure allows the atlas (C1) to pivot around the axis, enabling the movement of the head from side to side.
Where is the odontoid process?
This is also knows as the Dens.. It is located with the Atlas (c1) and the Axias (c2) it helps with the rotation of the head.
What bone is unique to the axis vertebrae?
The atlas, also known as C1 sits on the axis, or C2. The dens of the axis projects through the vertebral foramen of the atlas and the vertebral facets come in contact with each other through cartilaginous discs between the two vertebrae.
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."
