vertrebral joints/ligaments Flashcards
anterior longitudinal ligament
unite vertebral bodies on ant side
-stronger than posterior
posterior longitudinal ligament
inture vertebral bodies on post side
-resis flexion
ligamentum flavum
unites lamina
interspinous ligament
unite spinous processes
-absent or lacking in lumbar
supraspinous ligament
unite tips of spinous process
-stability in cervical/lumbar regions
ligamentum nuchae
only in cervical region
- both spinous and interspinous ligaments
- substitute for bone and muscle attachment
tranverse ligaments of atlas
holds dens against arch of atlas
-stabilize during rotation
alar ligament
tip of dens to occipital condyles
-“check” for flexion/rotation
apical ligament
tip of dens to internal occipital bone
-deep to cruciform
cruciform ligament
- cross shaped
- superior part blends w/ apical lig
- inferior attaches to bodyy
- blends w/ transverse lig
anterior atlantooccipital membrane
- attach anterior arch of atlas to anterior mrgin of foramen magnum
- continuation of ant long lig
posterior atlantooccipital membrane
- attach posterior arch of atlas to posterior margin of foramen magnum
- continuation of ligamentum flavum
tectorial membrane
body of axis to internal surface of occiptial bone thru foramen magnum
- superficial to cruciate lig
- continuation of post long lig
zygopophyseal joint
- synovial joint btwn sup/inf articular processes
- gliding joints
- articular process lined w/ hyaline surrounded by loose connective tissue capsule
- ligamentum flavum stabilizes
intervertebral joints
btwn vertebral body and IVD
-supported by ant/post long lig
