Axis Vertebrae Identification Flashcards

Study Notes

Axis Anatomy and Structures

The axis is the second cervical vertebra, also known as C2, pivotal for head rotation.
The axis body (centrum) serves as the main weight-bearing structure, providing support and stability to the vertebrae.

Odontoid Process

The axis dens (odontoid process) is a peg-like projection that extends upward from the axis, articulating with the atlas (C1) to facilitate rotational movement.

Transverse Processes

Transverse processes of axis are lateral bony projections that serve as attachment points for muscles and ligaments, crucial for neck movement and stability.

Foramina

Transverse foramina of axis are openings in the transverse processes that allow the passage of the vertebral arteries and veins, vital for blood supply to the brain.

Spinous Process

The axis spinous process is a prominent posterior projection that can be felt as a bony bump at the back of the neck, providing attachment for muscles and ligaments.

Articular Processes

The inferior articular process connects the axis to the cervical vertebra below (C3), playing a key role in maintaining stability and allowing for smooth movement between vertebrae.
The axis inferior articular facet is the surface on this process that articulates with C3, essential for intervertebral motion.

Superior Articular Facet

The axis superior articular facet provides a surface for articulation with the atlas, enabling rotation and nodding of the head while maintaining a secure connection between the vertebrae.
