Anatomy, Physiology and Neuroscience

i was watching house the other day. and ther was this guy. was about to die on his deth bed. and all of a suden his wife had trouble brething then stoped. and the husband lened up and started screming help her. then for like 3 days he was helthey but was still dieing so my question can willpower cause a suden bost of recovery.

1. which is not true? a. erythroblasts synthesize hemoglobin b. erythroblasts lose their nucleus and become reticulocytes that are released into the blood c. blood cell formation must be about the same as blood cell destruction d. erythropoietin from the kidney and liver stimulates hemopoiesis e. all of the above are true statements (i chose answer c) 2. which is not true about iron a. fe2+ is more absorbable than Fe3+ b. Iron is stored in the liver by joining to apoferritin to form ferritin c. iron is attached to each of the amino acids in hemoglobin d. iron is transported by transferrin e. women have a higher daily requirement for iron than men (ch…

A number of epigenetic studies suggest the existence of non-mendelian mode of inheritance. One of the more fascinating findings is the observation that exposure of mice to an enriched environments not only enhances long-term potentiation (a mechanism involved of memory formation), but also enhances LTP in their offspring during early adolescence, even if they do not experience an enriched environment themselves: The Journal of Neuroscience, February 4, 2009, 29(5):1496-1502; doi:10.1523/JNEUROSCI.5057-08.2009 Transgenerational Rescue of a Genetic Defect in Long-Term Potentiation and Memory Formation by Juvenile Enrichment Junko A.

I am currently culturing mouse fibroblast cells for an undergraduate research project, and I was wondering where the fibroblast cells are located in the mouse? I know they are cells found in connective tissue and form an ECM, but are they found in a specific type of connective tissue?

Is there a scientific explanation behind why men (who have a mate) stare/look at other women, even if they have no intention to cheat? Is there something in the human brain that causes this behavior? Are there any scientific articles to support this?

I've been doing some research into parts of the brain and what they do. The inferotemporal cortex, for example, has a lot to do with recognizing people's faces. But I'm wondering what part of the brain becomes active when we distinguish between male and female faces, and then see them as sexually attractive or unattractive. If there is a brain part for this, it must be somewhere near the inferotemporal cortex. Am I right?

Hey all, People often tell me that drinking lowers your IQ. And that if you drink regularly, it will be a permanent effect. I even remember a biology teacher once telling a class this. Do you think that alcohol consumption has any permanent effect on intelligence? Can you drink heavily for say, 5 years, and still have the same IQ once you stop? I wonder if there's any research to shed some light on this issue.

How come boxers break their hands so often if the gloves are supposed to protect their hands? Also why is the glove designed so that you cannot make a proper fist? I figure this has something to do with anatomy and physiology.

Does anybody know an acronym to name the parts of the cerebral cortex? Or does anybody know an acronym that could help me remember the functions of each section of the cerebral cortex? Thanks

Hi... In reference to “Somatic” nervous system..... I understand it’s use with the Motor division (efferent). Voluntary, innervates skeletal muscle.... No problem.. But how can “somatic” be voluntary with the Sensory division (afferent)? Receives sensory information from skin, fascia, joints, skeletal muscle. Am I missing something here? Any opinions, suggestions and comments will be appreciated Thank you in advance...

Hey, Hearing the joints 'crack' is nothing new to me, of course, but I never really researched the real reason. Someone told me it's bubbles within the joints, but I've never researched this. Recently, my knees have been talking.. a lot. I mean, every two movements (literally) they pop. It's not usually painful, I barely feel it, but it's quite disconcerting. I'm already scheduling a doc's appointment, but it takes a while to get a specialist, and for now I'm kinda weirded out. Can anyone help out with an attempted guess at what may cause this? I'm not in top shape but I have been training in the gym, and I've tried to refrain from running on the treadmi…

I've heard of people being overhormonal, with it's different causes and effects. But can someone give me more information on this subject? What usually causes a person to become overhormonal? What are many of the effects or symptoms? And encase you're wondering, the reason I ask, is because I have huge manboobs for a male of my size and age, and I'm also harrier than any of my friends that are my age. People have said that it could have something to do with being overhormonal/having overactive or dysfunctional hormones. So I'm just curious, and decided to see what some rather more credible, intelligent sources could say about the subject.

Could you somehow alter the brain so that a person was unable to feel fear? Like that girl Gaia Moore in that series by Francine Pascal?

Please help me solve this if you can – any suggestions are welcome! Sorry this is a bit of a long post. I’ve bolded all the important stuff, so if you want you can skim it and see if you can come up with a solution at the end. ***** On Thursday and Friday I rewarded myself for having a diet with virtually no junk food 98% of the time. As a ‘compensation’ for holding out so long, I ate a LARGE amount of chocolate, and piled on the ‘evil’ refined sugars. I had more mental energy in those 48 hours and felt better than I had done in weeks or even months! What’s more, after 3 and a half hours of hard exercise, I felt like I could jump a horse – literally! …

Are all warm blooded animals regulated at 37 C ? Why 37 ? Why fever does not go beyond 42 C ? Is it at 42 C the sickening microorganisms are 'killed' by the body thermal rise defense ? In occasions with near 42 C fever, I have had allucinations, and after that, a relief/cured sensation. What goes on ? Did the fever actually killed the 'illness' ?

Alien hand syndrome - Can the brain have two separate consiousnesses? My original idea for this post was that it maybe possible to have two separate consciousnesses in one brain (One dominant and one sub-dominant.) from birth, thus giving rise to alien hand syndrome. This lead me to consider how frustrating it would be to be the 'sub-dominant consciousness; to be self aware in a body you had little or no control over except for the manipulation of one limb. Firstly, it is known to be possible to live a relatively normal life with only one cerebral hemisphere. In cases of severe brain trauma (e.g. gunshot wound to the head) an entire hemisphere is removed along wit…

Can the effects of intoxication be overcome by willpower, whether it be from alcohol or any other mood-altering drug? I'm guessing mind-altering drugs that modify your perceptions probably can't be overcome through willpower...

Sometimes if I've been sitting still too long or just feel tense, I have involuntary movements, my head jerks from side to side a little. My hair stands up on end too. Does anyone know what causes those?

Greetings All I'm wondering what makes it is possible for me to be able to raise my BP and pulse whenever I want by simply "willing it" (for a lack of better words)? I can make it happen instantaneoulsly. I've been able to do this since I was a child. In addition, this is even harder to explain, I'm able to "flex" something inside of my ears! I must sound like a nut job, and cringe as I'm writing this:embarass:. Just wondering what makes it possible for me to have this weird and obviously useless ability that I've told NO ONE about. Can anyone else do this? Thanks in advance.

This is probably a stupid question but… How exactly do oxygen and nutrients reach the bone marrow? I asked in the forum and someone gave me this: http://en.wikipedia.org/wiki/File:Illu_compact_spongy_bone.jpg But that still leaves the fact that some part of the circulatory system; some vain and artery, would have to go through the bone and supply blood to the marrow.

Why don't fat grafts take? Why do they not adhere to the area to which they are grafted onto?

Researchers have discovered the use of deep brain stimulation can cause a boost in memory. Please take a look at the BBC article below... http://news.bbc.co.uk/1/hi/health/7213972.stm From the BBC article;

My friend's mum told her not to stand in front of the microwave when it's heating up food, because she said that it heats up your organs. Can microwaves melt your organs ??
