Acknowledgement
The authors sincerely thank those who donated their bodies to science so that anatomical research could be performed. Results from such research can potentially increase mankind's overall knowledge that can then improve patient care. Therefore, these donors and their families deserve our highest gratitude. We are grateful to the School of Anatomical Sciences of the University of the Witwatersrand for giving access to the Human Collections and to Mrs. H. Ali for assistance with histology.
