Hello everyone, it's David here from Flashka. I can see you having some doubts while studying, and we are here for you. By going into the PDF View, you can simply highlight and ask for a simple explanation from our Professor Ka.
If you have more questions for him, you can simply highlight and, suppose you're willing to know where the medulla is located, you just go and ask him "where is it located?" and he will tell you instantly.
So we support you also in the understanding phase and hope this helps resolve your doubts. Enjoy studying!
