occipito-

Any segment of the cervical spine may be affected by the rheumatoid inflammatory process, but destructive changes are most prominent at the occipito atlantoaxial junction.

Other notes may include LOA or LOP, which stand for 'left occipito anterior' or 'left occipito posterior'.

Several brain structures other than the amygdala have also been observed to be activated when individuals are presented with fearful vs. neutral faces, namely the occipito cerebellar regions including the fusiform gyrus and the inferior parietal / superior temporal gyri.

When the disease affects one of the occipito atlantoaxial articulations (termed lateral mass) it may produce the syndrome of non-reducible rotational tilt of the head, the main clinical features of which are occipital pain, tender points in the neck, and tilting of the head toward the affected side.
