A 33-year-old male patient complains of feeling severe pain when he tries to turn his neck. A physician realizes that the problem is in his pivot (trochoid) joint. Which of the following joints would most likely be examined?
1.Atlantoociipital joint
2.Atlantoaxial joint
3.Carpometacarpal joint
4.Proximal tibiofi bular joint
5.Intervertebral disks
exp:
The atlantoaxial joint is the pivot or trochoid joint. The atlantooccipital joints are the condyloid (ellipsoidal) joints, the carpometacarpal joint of the thumb is the saddle (sellar) joint, and the proximal tibiofi bular joint is the plane (gliding) joint. The intervertebral disk is the secondary cartilaginous (symphysis) joint.
