Summary of Vertebral Joints of C, T and L Spine
Question | Answer |
---|---|
What is joint between the skull and C1? | atlantooccipital |
What are the joints between C1 and C2? (right and left lateral and medial) | atlantoaxial |
What are the cartilaginous (symphysis) joints between C2-T12? | intervertebral |
What are the synovial joints between C2-T12? | zygapophyseal |
What are joints between T1-T12? | costovertebral |
What are the joints between T1-T10? | costotransverse |
Where is the medial joint of C1-C2 located? | between the dens of C2 and anterior arch of C1 |
Where are the lateral, right and left, joints between C1-C2 located? | between the lateral masses of C1 and superior facets of C2 |
Most of the vertebral joints of the C and T spine are classified as what? Describe | snynovial (enclosed in a capsule that contains synovial fluid), diarthrodial (freely movable) |
Which vertebral joint of the C and T spine is classified differently than the others. Explain | intervertebral; cartilaginous (symphysis), amphiarthrodial (slightly movable) with no movement type |
What type of movement does the atlanto-occipital joint of the skull and C1 have? | ellipsoid (condyloid); flexion and extension, abduction and adduction, circumduction |
What type of movement does the lateral atlantoaxial, joints between the lateral masses of C1 and superior facets of C2, have? | plane (gliding); a sliding or gliding motion between the articulating surfaces with some rotational movement |
What type of movement does the medial atlantoaxial joint between the dens of C2 and anterior arch of C1 have? | trochoid (pivot); allows rotational movement around a single axis |
What type of movement does the zygapophyseal (C2-T12), costovertebral (T1-T12) and costotransverse (T1-T10) joints have? | plane (gliding); a sliding or gliding motion between the articulating surfaces with some rotational movement |
What are the L-spine zygapophyseal joints classified as? What is the mobility type? What is the movement type? | synovial (lined w/synovial membrane); diarthrodial (freely movable); plane (gliding) |
What are the L-spine intervertebral joints classified as? What is the mobility type? What is the movement type? | cartilaginous (symphysis); amphiarthrodial (slightly movable); no movement type |
