Definition
An interparietal bone (os interparietale or Inca bone) is a dermal bone situated between the parietal and supraoccipital. It corresponds to the upper portion of the squama of the occipital bone that lies superior to the highest nuchal line and is completely fused to the supraoccipital. However, in some individuals this portion remains separate from the rest of the occipital bone throughout life. In such cases, this separate bone is particularly referred as 'Inca bone'.
