Shalom Aleichem Rav Tendler. I was listening to the Rav's shiur and I have been learning siman 183 Hilchos Niddah and I just cannot find an adequate diagram of the female anatomy which explains rashi vs the rambam with regard to the Lul etc. I have had specific difficulty with the Shulchan Aruch Harav siman 183 which delves into the differences between Rashi and the Rambam. Would the Rav be able to help me in this area? Does he know of a good diagram or place to look to explain the anatomy? What makes it more confusing is that it seems anatomically the Lul does not exist in today's science? I would be so grateful for some elucidation on this subject. Thank you in advance for your time.
