    The reason khan academy is amazing is because it appreciates scientific concepts and phenomena as something to be appreciated and marvelled at, not mugged up

      It is nice to know that Bernie is interested in this topic. After hearing this topic you appreciate your body and your health. Teaching people to maintain our health is very important, Check out www.PromotingHealthyCommunities.com. See: Surgeon General: " The economy doesn't do anything without a healthy work force", Bernie can have a HUGE VOICE in improving our health care system. May God bless you as your continue to serve our citizens

      Mr Sanders, its a pleasure to see you enjoy learning medicine. Im a first year medical student in a caribbean medical school. I was raised in Cuba, where most of my family members are physicians themselves. Where people have absolutely no access no medical supplies, medications, xrays, where my aunt died from there being no doctors to see her in an emergency, where my uncle went blind from there being no electricity to have the operating room available for ocular emergencies..these r the routine cases in Cuba..where there is "free medicine". Socialism/communism is the saddest, most diabolical system humanity has practiced..believe me..i have read Carlos Marx etc..i only wish it would actually work..u are either profoundly ignorant, naive, or simply..a hippocrite. May God bless you 🙏

    Actin and cancer migration and metastasis is what Im studying for my PhD! :D Amazing movement of the cells, you have to see them live to appreciate the sheer dynamic of the cells and all the ruffles and protrusions, woven around.

      In Brazil,we learn about cytosqueleton in high school, and overall about the cell in quite some depth. However most of it fells like dry and useless. Knowledge uncontextualized

    I always have on question. Is the cell structure predetermined like our body ... (we have an exact location for liver, hearth, lungs, arms etc) or is random determined by molecular entropy ? Are the organelles position, number encoded predetermined or random ?

    • @Sage_ping
      @Sage_ping 3 года назад +2

      maybe like microtubules in cells, something holds the organs in the exact place in every human being ,we just haven't discovered it yet ,maybe sometime in the future the answer will be clear

    Are you sure the cytoskeleton filament you highlighted is the microfilament? The peach colored filaments look more like microfilament to me.
    The one you highlighted looks more like the intermediate filament.

    • @sammansour4374
      @sammansour4374 5 лет назад

      thin peach-colored are actin filaments, the darkest one is an intermediate filament, and the thick light blue is microfilaments
