What are the 3 primary factors that effect the degree of movement of a joint?
- Articulating bony surfaces
- Ligaments
- Muscle tone
What are the secondary factors affecting the degree of movement of a joint?
- Skin
- Fascia
- Bursae
- Synovial sheaths
What are some ways to tell if a joint is designed for structure or mobility?
Joints designed for mobility tend to have smaller surface areas
What are the 2 major sub-classifications of joints?
Solid joints
Synovial joints
Solid joints can be subdivided into what types of joints?
Fibrous and cartilaginous
What are 4 distinguishing features of synovial joints?
- Joint cavity
- Articular cartilage
- Synovial membrane
- Fibrous capsule
What are the types of synovial joints?
Condylar
Gliding
Hinge
Ball and Socket
Saddle
Pivot
Horizontal spinal facet surfaces […] axial rotation
Vertical spinal facet surfaces […] axial rotation

- What are the 3 MAJOR factors contributing to the stability and mobility of the spine?
- What additional factor limits movement of the spine?
- What additional factors facilitate movement of the spine?
- Orientation of facets; Orientation of spinous processes; Size of intervertebral discs
- Supporting structures
- Activation of the neuromuscular system
Vertebral body symphysis is […]
Articulation between adjacent vertebral bodies
Facet synovial joints in the vertebral column refers to […]
Articulation between superior and inferior facets
What are the supporting structures of symphysis joints and what are their functions?
Intervertebral disk
Anterior longitudinal ligament - Limits extension of vertebral column and maintains stability of intervertebral discs
Posterior longitudinal ligament - Restricts flexion of vertebral column and posterior herniation of discs
- What are the supporting structures of the vertebral facet articulation?
- What is their function?
- Ligamentum flava - resist flexion of vertebral column
- Interspinous - limits flexion of vertebral column
- Intertransverse - limits lateral bending to contralateral side
- Supraspinous - limits flexion of vertebral column
- Ligamentum Nuchae - attachment for trapezius and rhomboid minor, support neck, prevent hyperflexion
Predict the direction an intervertebral disk will protrude (herniate) with excessive force into flexion or extension of the spine.
The nucleus pulposus is most likely to herniate through the annulus fibrosis at the posterior lateral disk space
