Median atlantoaxial joint - a synovial joint between the odontoid process of the axis and the anterior arch fo the atlas anteriorly and the transverse ligament posteriorly. p 189 fig 14-11

|
Definition
The combined motion axial extension also called cervical retraction is flextion of the skull on C1 and extension of C2-C7
Or you could say Flexion of the atlantooccipital joint and extension of C2-C7
Standing up straight accentuates cervical retraction |
|
|
Term
| Cervical protraction involves |
|
Definition
extension of the atlantooccipital joint (skull-C1) and flextion of C2-C7
Looking at a computer screen through bifocals accentuates cervical protraction. |

Fryette's laws of spinal motion.
1. When the thoracic and lumbar spine is in neutral unilateral side bending will be accompanied by rotation to the opposite side.
2. When the spine is flexed or extended(non-neutral) unilateral sidebending will be accompanied by rotation to the same side.
3. Any time a spinal segment moves in one plane available motion in the other planes decreases. |
