Its anterior surface is convex, and presents at its center the anterior tubercle for the attachment of the Longus colli muscles and the anterior longitudinal ligament. Posteriorly it is concave, and marked by a smooth, oval or circular facet (fovea dentis), for articulation with the odontoid process (dens) of the axis.
Is the pedicle anterior or posterior?
The pedicles are anchored to the posterior side of the vertebral body. Each lamina forms part of the posterior roof of the vertebral arch. The large opening between the vertebral arch and body is the vertebral foramen, which contains the spinal cord.
What is the dens of C2?
Dens (Odontoid) Fractures – General Review A fracture of the odontoid bone (also called the dens), is an upward extension of C2 cervical vertebrae (i.e., axis) up into the C1 cervical vertebrae (i.e., atlas) and is held in place partially by the alar, apical and transverse ligaments.
What is the difference between atlas and axis vertebrae?
The atlas is the first cervical (neck) vertebra which is just under the head; it is named for Atlas, the Greek god who supported the world on his shoulders. The axis is the second cervical vertebra; it has what is called the odontoid process about which the atlas rotates. It allows the head turn from side to side.
What are atlas and axis?
The atlas and axis vertebrae are the two most superior bones in the vertebral column, and they are part of the seven cervical vertebrae. The atlas is the top-most bone, sitting just below the skull; it is followed by the axis. Together, they support the skull, facilitate neck movement, and protect the spinal cord.
Is the dens on C1 or C2?
C1 and C2 vertebrae. The C1 vertebra, also called atlas, is shaped like a ring. The C2 vertebra has an upward-facing long bony process called the dens. The dens forms a joint with the C1 vertebra and facilitates its turning motions, thereby allowing the head to turn in different directions.
What are the dens?
The odontoid process, also known as the dens, is an upward projectile of bone that arises from the front part of the center of the axis vertebra. This arrangement allows for a lot of freedom of motion between the combination of the head, first vertebra (atlas), and 2nd vertebra (axis).
