Honors A&P I

Science Wednesday - Nervous and Blood?!?!?!

Hey there kiddos - here's the assignments for this week's Science Wednesday.  You've got a mixture of topics, including sleep, hallucinations, and fetal blood.  Enjoy!

1.  TED Talks - Sleep - no, don't sleep, yet - but listen to why we need sleep.

2. SciShow -  SciShow - Hank's at it again - this time to teach us about a hallucinations!

3.  Radiolab - I may have mentioned this in class before but it fascinates me enough to have you listen . . it's all about fetal consequences.


Remember, you need to answer the questions AND have two blog posts - one reflective post of your own thought**see question #12 for additional instructions!** and one (thoughtfully and respectfullly) responding to a classmate's reflection (with more than just "I agree with what you said").  Happy listening and watching!

20 comments:

  1. (Sleep)-Foster discuses at the end of the talk how schizophrenia is linked to the lack of sleep during the developmental stages of life. This and many other mental diseases are linked to the lack of sleep. Taking it from a quirky stand point here, but if the lack of sleep is due to an "activity" that is supposed to help keep young adults healthy and educated, wouldn't keeping them up actually inhibit their sleep. So by that logic, I take it that those who spend hours upon hours studying to make the grade are more likely to develop a mental illness over those that do not study for hours. Funny how society has let this be known that lack of sleep does this and there really is nothing we have tried to do to stop it or at least help it.
    (Hallucinations)- Hank discusses what hallucinations actually are, and I understand that. I have one question is it entirely possible for a person to hallucinate for the rest of their life? Acid has a "MINOR" side effect of sometimes trapping you within an acid trip. Is it possible for the brain to do that on its own, and completely destroy vital functioning processes in the process?
    (Fetal)- There are many factors that determine the fetal cells of a child within the mother. Most of which arrive from the mother, father , and the environment around the mother. With the expansive amounts of DNA around the world there can be no correct cell that will completely help the mother or hurt her. With disease mutating today more than they had in the 1900's one can only assume that when one cell cannot help the mother any more that it will soon start to hurt her, and vice versa.

    1. I agree with you about sleep. It is interesting that society has us work more and spend less hours sleeping when it could literally keep us healthier.

    2. I find your analysis of the consequences of lack of sleep to be very interesting, and I find myself asking the same question at times as well. Teachers can sometimes push us or overload us with work, limiting that amount of sleep we get, which can actually make us perform with a lesser quality in class!

      I find your question on whether or not the brain can lock itself to be very interesting. It's something I've never considered before, and it would be scary if it were possible. Imagine being locked in a constant hallucination by no fault of your own!

  2. I found this weeks Science Wednesday videos to be very interesting!

    Sleep - I always knew that sleep was good for us, and that people never seem to get enough of it, but I didn't know that it had so many consequences for not getting enough of it.

    Hallucinations - Hallucinations have always seemed peculiar and fascinating to me, so it was kind of cool to learn about what can cause hallucinations, and how there are different kinds. I never knew that people that go blind can hallucinate images! Thinking about it know, phantom limb syndrome could be considered just another king of hallucination, since it's just a sensory deception.

    Fetal - I never knew that fetal cells "leaked" into a mother's blood stream, let alone that they stay there for decades afterwards. I found it really interesting that although they seem to be helpful in keeping the mother healthy, the cells can actually attack the mother and make her condition worse. It's cool to think about how my cells, and all of my siblings cells, are just floating around my mom's blood stream right now.

    Here are two A&P videos I found, one about the Uvula, and one about what causes "Pins and Needles"

    1. Replying to your sleep comment, there are so many consequences of not getting enough. However, even though we all know them, it is hard to do something about it. In the society we live in today, the days are almost "shorter". We have more things to do, more distractions, and more reasons to not sleep. Personally, I can't go to sleep without checking off every mental to-do list in my head. Even if I am extremely tired and know they will have a negative effect on me later. Also, we don't live in a day where we can just chuck our alarm clocks out the window. They are instrumental to daily life. Being on time is an important thing that can;t be chanced. I find it all very interesting.

    2. Good comparison between the last two Science Wednesdays, I like that. Also good video topic. The topic of hallucinations is fascinating when your think that everyone can experience them at any given moment. I believe that the brain is a very complex organ that can send missing signals from one synapse to another.

    3. I also didn't know that many of the consequences of loosing sleep were so prominent or important, some are much more long term than i thought.

  3. I thought that the hallucinations one was very interesting. I had never thought about that when I sick and can't smell anything but decide I can smell something it is a hallucination. I had always thought that hallucinations were only visual when someone it sick.

    1. I agree. The hallucinations were very interesting. They are always associated with mental illness, but really they're a fairly common thing that can happen to anyone, and often do happen to everyone. Minor things like smelling or tasting something that isn't there we laugh at and thing " oh that is peculiar," we don't think "hey I'm having a hallucinations." Very interesting.

    2. I thought the same thing Emily. I always thought that hallucinations were just visual! I assumed that it was only when someone was really sick and on medications. I also thought your video was very interesting!

  4. I find a hallucinations very interesting. Everyone hallucinates, but most people don't think of it as a hallucination because our society associates it with mental illness. I've hallucinated at times where after I realized it was a hallucination, and times where i didn't. Everyone been able to taste or smell something they're thinking about, but don't actually have. I've also hallucinated because my brain freaked out when I had a fever because I had the flu. However, that hallucination was scary. Most hallucinations aren't. Many are often pleasant. I did not know that there was two types of hallucinations until watching this show.


    I also found the fetal cell thing very interesting. It's crazy that your cells are still in your mother. I wonder if the cells have any predisposition to attack or to help, or is it just circumstantial. Maybe if the mother gets a disease (non-autoimmune) then the fetal cells rush to help, but if she has an autoimmune disease, and her body starts attacking itself, then the fetal cells follow. A " Monkey see- Money do," concept. I think it will be interesting to see what they discover with further research.

    1. Going along with your comments about hallucination, I thought they were rather a weird subject. The fact that something can cause your mind to create sensations out of thin air is so interesting, but rather scary at the same time. The idea that someone could be having a normal day but then hallucinate that the walls are changing colour is a very strange thought, all in all. All together, I suppose you could just leave the whole subject with "Hallucinations are weird" and be good.

  6. The video that I found most interesting this week was Fetal Consequences. Before, I had no idea that my cells were floating around in someone other than me, my mother. My initial question was why do they work in her body and not mess up something? I always thought that my cells were somewhat specific to me and couldn't be "easily transferred". When he started bringing up positive and negative effects on the mother, I found it amazing. The cells don't even stay dormant, they are interacting with my mother's body. This makes me wonder what effect I or my siblings will have on my mother, similarly to what the guy in the video is wondering himself. It's insane how one day I can save my mom while fighting cancer and the next day I can help her attack her autoimmune disease.

  7. My interesting Ted Talk video:

  8. I always knew that sleep was important, but it never occurred to me exactly what I lose when I stay up late doing something. The fact that I can change my levels of memory and focus, purely based on sleep, is really an interesting thought. I also thought it was good to find out that a teenager's body clock is set to fall asleep late and wake up late. I always just thought that I was lazy. While it may be true to an extent, it is good to know that it's not all me, but that it is partially my body.

  9. This weeks videos were pretty cool. The hallucinations was by far the best for me. I did not know the difference between psychotic and CBS hallucinations before watching the crash course. The Ted talk was interesting in the three reasons for sleep being needed. I would personally lean towards the first it seemed to have more science behind it. http://www.ted.com/talks/jennifer_doudna_we_can_now_edit_our_dna_but_let_s_do_it_wisely

  10. I enjoyed all of the parts to Science Wednesday this week. My favorite one to listen to was the Ted Talk about sleep. It really made me think about how important time management is, not only to get everything done, but also to make sure you're getting enough sleep. It also answered questions about how much sleep we really need and that everyone is different when it comes to the amount of sleep they need.

  11. I most enjoyed the hallucinations video, I've never really learned anything about them and I thought it was very cool. Although I'm a bit disappointed that I can't say I've ever hallucinated. The different triggers that can cause hallucination interested me particularly because i didn't know that you could hallucinate from stress or grief.

    Also reading other comments about the fetal cell makes me sad because mine wouldn't work and it seems really cool and interesting.

  12. ( ABBIE DEMPSEY )I found the sleep talk very interesting and motivating. I didn't realize how active your brain is during sleep and the importance of creating a dark and quiet environment for you to sleep in. Usually I sleep with a closet light on but I have been trying to sleep without this and see if it makes a difference.

    I definitely notice a change in my mood and attentiveness when I lack sleep and find that I eat unhealthier foods.

    I was most interested in the hallucination video so I searched to find another cool video on hallucinations. I cam eacross this video on SALVIA. https://www.youtube.com/user/scishow/search?query=salvia
