C-Spine Joints and Ligaments (Quiz 3) Flashcards
Articulation of two vertebrae with no Intervertebral Disks
Craniovertbral Joints
Condyloid Joint
Where the Superior Articular Facets on the lateral masses of C1 articulate w/ the occipital condyles of the Skull
Atlanto-Occipital Joint
Movements of the Atlanto-Occipital Joint
Flexion of the head on the neck
Extension of the head on the neck
(Nodding action/Bobble Head)
A membrane that acts like a ligament
Supports the Atlanto-Occipital joint and prevents excessive flexion/extension of head on the neck
Anterior and Posterior Atlanto-Occipital Membrane
Pivot Joint
The Articulation of C1 and C2
The Articular facet of C1 articulates with the Dens of C2
Atlanto-Axial Joint
Movement of the Atlanto-Axial Joint
Rotation
(C1 rotates around the Dens of C2)
Ligament that holds the Dens of C2 against the anterior arch of C1
Transverse Ligament of the Atlas
(Part of the Cruciate Ligament)
Ligament (band like) that travels from the transverse ligament to the Occipital bone (superiorly) and to the Body of C2 (inferiorly)
Cruciate Ligament (of the upper C-Spine)
(makes a cross with the Transverse ligament of the Atlas)
Ligament that travels from the Dens to the lateral margins of the foramen magnum (hole in the base of the skull)
Prevents excessive Rotation
Alar Ligament
Ligament that travels from the Dens to the Anterior margin of the Foramen Magnum
Apical Ligament
