The number and location of the parietal foramen in human skulls.

The number and location of the parietal foramen were examined in 100 skulls of brazilian whites, negroes and mulattoes. The authors observed its presence or absence, the lateral differences, the bilateral symmetry, the existence of a median or multiple foramina and the perforation of one or both tables. The parietal foramen was more frequent in the right side than in the left, but the difference was statistically not significant.
