my main concern is to know about morphogenetic movement.

Gastrulation in Human Embryo\n\nDelamination precedes gastrulation separating ICM into epiblast & hypoblast \nGastrulation occurs in epiblast (future embryo) \nGastrulation involves several types of movements and shape changes \nEnd product is three germ layers: ectoderm, endoderm and mesoderm \nThe expression of certain genes regulates the formation of the embryonic axes & the organization of the embryo \nThe Timing of Gastrulation and Subsequent Events\nGastrulation begins about 15 days of development and is followed by neurulation and the start of development of several major organ systems \n\nRole of Gastrulation\nGastrulation will covert the bilaminate epiblast into the three primary embryonic germ layers \nEctoderm: outside; this embryonic layer more or less surrounds the other germ layers \nMesoderm: middle; this germ layer lies between the ectoderm and mesoderm \nEndoderm: inside; this germ layer lies at the most interior of the embryo \nSubsequently neurulation will form epithelial and neural ectoderm from the ectoderm \n\nDuring human gastrulation, cells move over the blastodisc surface, enter the primitive streak and move internally. On the surface they move in association with other cells but once they turn the corner around the lip of the primitive streak the cells separate as individuals to migrate internally to form the mesoderm and endoderm. These are just some of the types of cell movements that occur in animal embryos. Here's a full list\n\nIngression: cells break away from the tissue and migrate as individuals \nDelamination: layers of cells separate from each others more or less as sheets of cells \nIntercalation: two cell layers interlace with each other \nEpiboly: a form of cell spreading in which cells flatten out; this allows them to cover a much larger surface area (1st detailed in frog development). \nInvagination (Evagination): a tissue layer folds in (out) \nInvolution: cells move over a lip of tissue and into the interior \nConvergent Extension: cells reorganize to form less layers allowing the cells to extend out from a point. \nNot all of these morphogenetic movements have been detailed in humans but they all have been shown to occur in other animals. Also remember, one type of cellular rearrangement does not exclude another with several different types of movement potentially occurring at the same time.

From what I have found (which wasn't much) it seems to be a surgical procedure.  I will add the sites I have looked at but the are very technical and aimed at surgeons.\nI hope they will be of some help to you.

Don't panick or feel terrible over this. I don't know about your problem, but I have heard of this before. From what I understand, it's not dangerous, but you might want a doctor to take a look at it. Really, this is the only way that your mind will be put at ease. I wish you the best.

I think it would help your paper to say why you think each of these things might occur, and even add some references that support your reasoning. You might be interested in the "Trends in Evolution" part of the web page I have linked at the bottom to help your make predictions.\n\nWhy do you think sexual dimorphism would change in the future, and why would it get more apparent if sexual roles are becoming more equal? (in general sexual dimorphism has been decreasing in human evolution - see link below, about 2/3 of the way down the page)\n\nWhy do you predict they will get taller (this is a good prediction, by the way, but why do you think it to be true)? \n\nIs there any reason to think that ESP or telekinesis will become possible?? (probably not, in my opinion, but what data can you find that says one way or the other)? \n\nIf you have read something that supports what you are saying, and you can provide references in the paper, your arguments will be much stronger - increasing the probability of a good grade!!

Hormonal activity is usually a negative feed back mechanism. You would think exercise would feed forward, though, as the rate would keep increasing. Not my area, though, so a functional biologist is needed here.

haha so much for doing your hwk\nc d c c a b b d b b e? c b c? e a a a c b b a b? d?\n\nThats all i have time for... im dont remeber to much on this but best of luck to you\n\nLet me see if I can find my old textbook site and you can read it:\n\nah... here\nhttp://www.mhhe.com/biosci/genbio/maderbiology7/student/olc/chap08-outline.mhtml

The research done with mice and spinal cord injury is fascinating, yet does not touch the neural networks involved in memory and cognition, only motor function.  Much research has gone into embryonic stem cell research which could hopefully reverse the effects that the plaques have already caused on the brain.  Even more interesting work is being done in prevention.  Like many illnesses it is easier to treat if it never happens and like many illnesses it seems that exercise can help prevent the disease.  With the aging population I believe the interest in a cure and possibly vaccines for prevention may be on the way soon.

Great stuff going on right now having to do with developmental genes (like Hox genes).  You may know this as "Evo Devo" or evolutionary developmental biology.\n\nCheck out the book "Endless Forms Most Beautiful," by Sean Carroll.  He also gives ideas for research and new fields, lots of peer-reviewed papers.\n\nI just read it this Fall, it was great.

I guess this is a joke\n\nAnal Tooth Grow...\n\nAnd if its real you got a serious mutation, check your local scientist

Am I the only person that thinks a direct relationship between breast implants and the intelligence of the future is slightly worrying

Don't rush it. You will develope sooner than you would like. Once you are developed you might just wish that you were flat as a board again.

you are growing and you are going to short-circuit your growth cycle is you start dieting now.  Just let yourself grow up before you worry about your wieght.

Nahh... just observe how long you get to do that or if you still have hands. That's when you should worry.

A quotation by Harvey J Gold, Author of Mathematical Modelling of Biological Systems,  may go towards assisting your analysis of the situation:\n\n" The result of a mathematical development should be continuously checked against one's own intuition about what constitutes reasonable biological behaviour. Whenever such a check reveals disagreement, the following possibilities must be considered:\n\na : A mistake has been made in the formal mathematical development\n\nb: The starting assumptions are incorrect and/or constitute a too drastic oversimplification\n\nc: One's own intuition about the biological field is inadequately developed.\n\nd: A penetrating new principle has been discovered. "\n\nDo let me know whether you found meaning in the above, and if you did analyse your model based on the checks recommended by him, what among a,b,c,d was the reason of the discrepancy. Of course this is assuming that you have already established the discrepancy beyond doubt.

dear friend i feel ur position.. just search in google..that vl help u a lot
