Articular Processes on adjacent vertebrae

11
Q

Zyg. Joints allow ___ movement for (1) cervical, (2) thoracic, and (3) Lumbar vertebrae

A

Cervical: Flexion and Extension

Thoracic: Rotation

Lumbar: Interlocked to limit range of movement; some flexion and extension

Increase; Superior; Inferior

18
Q

Kyphosis

A

Excess curvature of Thoracic region; irreversible and age-related; Think: chin going to chest

Anterior: Hyperextension

Posterior: Hyperflexion

27
Q

Internal Vertebral Plexus

A

Valveless venous system running lenth of vertebral column. Blood flow can go either way but diseases (cancer) can spread easily too. Superior to the dura mater

28

A

herniation of nucleus pulposus material through age-weakened annulus fibrosus

32
Q

Coccygeal Ligament

A

continuation of the dura mater that extends below the end of the dural sac to attach to the coccyx.
