The site is fully funded, owned and maintained by Dr. Mohammad Kasem, professor of histology, Al-Azhar faculty of medicine in Assuit - Egypt. All lectures and quizzes published here are exclusively edited by Dr. Mohammad Kasem. Some of the included images & illustrations were obtained from textbooks and references on this page. Published Videos here are shared from their pages on the YouTube network. Videos are classified and organized according to each topic in the Histology course on this website. I sincerely hope you always find it updated and useful. Please do not hesitate to contact me whenever you have any comments or suggestions.
