RELATED TERMS--------------------------------------
Cervical
Having to do with the neck (cervical spine) or the cervix of the uterus.
Bone
Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.
Projection
A defense mechanism, operating unconsciously, in which what is emotionally unacceptable in the self is unconsciously rejected and attributed (projected) to others.

The joint between the axis and atlas is a pivot type of joint. It allows the head turn.

Ca

CA 125
A cancer marker, a protein normally made by certain cells in the body including those of the uterine tubes, uterus, cervix, and the lining of the chest and abdominal cavities (the peritoneum and pleura). CA 125 stands for cancer antigen 125.
CA 15-3
A tumor marker most useful in following the course of treatment in women diagnosed with breast cancer, especially advanced breast cancer. CA 15–3 levels are rarely elevated in women with early stage breast cancer.
CA 19-9
A tumor marker initially found in colorectal cancer patients, but subsequently also identified in patients with pancreatic, stomach, and bile duct cancer. In those who have pancreatic cancer, higher levels of CA 19–9 tend to be associated with more advanced disease. Noncancerous conditions that may elevate CA 19–9 levels include gallstones, pancreatitis, cirrhosis of the liver, and cholecystitis.
CA 27-29
A tumor marker similar to the CA 15–3 that is found in the blood of most breast cancer patients. CA 27–29 levels may be used in conjunction with other procedures (such as mammograms and measurements of other tumor marker levels) to check for recurrence in women previously treated for stage II and stage III breast cancer.
