    Study Notes

    Atlas (First Cervical Vertebra) Overview

    • Known as the Atlas, it supports the head.
    • Lacks a body and spiny process, featuring large superior facets.
    • Superior facets articulate with occipital condyles, facilitating nodding ("yes") and side tilting movements.

    Atlas, Lateral View

    • Visualization reveals the structure and alignment relative to adjacent vertebrae.

    Axis (Second Cervical Vertebra) Overview

    • Referred to as the Axis, it allows significant rotation of the head, enabling "no" motions.
    • Essential for head mobility and positioning.

    Dens

    • The Axis exhibits the Dens, a modified process on its small body.
    • Dens fits into the Atlas' enlarged vertebral foramen, allowing the Atlas to rotate around it for head rotation.

    Axis, Lateral View

    • Provides insight into the Axis's structure and its connection to surrounding vertebrae.

    Atlas and Axis Articulated, Superior View

    • Highlights the articulation between Atlas and Axis, illustrating their joint function and interdependence.

    Fifth Cervical Vertebra, Superior View

    • Details the anatomical structure and unique features of the fifth cervical vertebra.

    Fifth Cervical Vertebra, Lateral View

    • Offers a profile view to understand its placement and relation with other cervical vertebrae.

    Anterolateral View

    • Reveals additional perspective on cervical vertebrae anatomy, potentially demonstrating alignment and structural connections.
