    i'm not too good on youtube so instead of sending a message i'll just write here:
    i'm from Buenos Aires, in 2nd year of medschool and your videos are what i've been looking for on youtube for months. really. i don't understand why you don't pop up first on searches because your videos have been the most helpful, by far, i've seen. you explain things very clearly with the perfect amount of depth. thank you for everything you do, your videos and existing :) appreciate it loads.

    Man, you are an amazing teacher - finally i get to understand embryology. English isn't even my mothertongue and you speak quite fast, but how you structure your lesson is way better to understand than any lecture I heard or script and book I got to read in my german university so far. Thank you so much!

    Hello, I am also a medical student and these videos are amazing. You explain things very well and to the perfect level of detail. However, may I suggest that you either number your videos or tell viewers what video to watch next after the one they have just watched so they can follow the process. Ex: can you put all of the steps of the embryonic develop into order? Other than that, these are fantastic! Great job :)

    • @AKLECTURES
      @AKLECTURES  9 ปีที่แล้ว +2

      Mima Markicevic Hey there! thanks for the positive feedback! great to see that they're helping you on your medical track..The reason I do not order my videos on youtube is because i have an entire website dedicated to just that (plus much more to come in several months). So check it out if you're looking for well ordered and organized lectures! :)

    So one question I have is. What problems would an animal made of a solid spherical ball of cells experience? My answer is that cells inside of the spherical ball would have a hard time receiving nutrients from the surrounding fluid, excrete waste, and exchange gases. and blastulation fixes this problem by increases the surface area to volume ratio as well as exposing cells to outside fluid.

  • @krizzadiaz8426
    @krizzadiaz8426 4 ปีที่แล้ว

    Hi. This is very helpful.😍 Can I ask these question? 😊What would happen if one cell was removed or damaged at the 2 cell, 4 cells, and 8 cell stages?And What would happen if the two cells were separated after the first cleavage and allowed to develop on their own?
    I hope to get a response from you. 😊 Thank youuu.😊

    • @chayathangalapalli6908
      @chayathangalapalli6908 7 ปีที่แล้ว +4

      shishi Rad Well, there is another process called as compaction that takes place, where all the cells of the morula are kept together by tight junctions and they communicate via gap junctions. In case, a cell separates, that cell can form another morula, thus forming twins (identical /unidentical) rarely! :)

    If the first mitosis division doesn't happen until 30 hours after fertilization and the next few mitotic divisions take their time as well, how do you refer to that as "very rapid" mitotic divisions.

      morula is ball of 16 cells (mulberry)

    • @tonyberardi1617
      @tonyberardi1617 6 ปีที่แล้ว +1

      16-58 is considered a morula, since a blastocyst is defined as 58. So that assumes that 16 cells up to 58 is called a morula. They undergo mitosis, so from 1 cell to 2 to 4 to 16 to 32. 16 and 32 both are called morula. Don't watch a whole video and take away one thing to criticize and leave a one sentence comment to just call that thing out Source is my med school notes, which I trust lol
