The morphology of the perform aperture from digital images was captured using Adobe Measuring Tool 9.0 and data analyzed with SPSS 17.0. Twenty-four linear measurements from a central point of the aperture as well as the perimeter were evaluated to quantify a difference between Black and White populations. The statistical analyses employed Discriminate Functional Analysis followed by Stepwise analysis. Discriminate functions were generated to predict to which group a skull belonged. A discriminate function produced an accuracy of 77.4%. Step-wise discriminate function analysis, using only three variables, produced an accuracy of 79.0%.展开更多

Dissection showed that the right testicular vein demonstrated an abnormal drainage pattern by terminating into the right renal vein. The left testicular vein demonstrated a normal drainage pattern by terminating into the left renal vein. The unusual drainage of the right testicular vein into the right renal vein may complicate hemodynamics thus causing a varicocele. Complications of a varicocele could lead to testis atrophy and/or infertility. Knowing the anatomical variants of the testicular veins drainage pattern may help the surgeon avoid potential complications during routine laparoscopic procedures and may also uncover a reason for male infertility.展开更多

Inca bones or interparietal (supernumerary) bones are rarely seen among dry human skulls. Their frequency of presentation is much less than that of sutural or Wormian bones. Inca bones or interparietal (supernumerary) bones are accepted as normal variants most often found in the occipitoparietal region of the skull. Their characteristic shape, a triangle, resembles a monument design of the Inca tribe of South America and Latin America. The significance of the presence of these variants is that Inca bones or interparietal bones may be mistaken for a skull fracture. They may also be very useful in forensic identification of an unknown individual.展开更多
