Anatomy, Physiology and Neuroscience

At least, that is the theory I read about. Any light to shed on this subject?

Hey guys! Is there a "keyhole-access" from inside the mouth to the Bichat-Fat-Pad (=Buccal Fat Pad=Corpus adiposum buccae), without cutting the Muscle (M. buccinator) ? The Bichat-Fat-Pad is the buccal fat pad, lying deep in the cheek, under the M. zygomaticum major, superficial to the M.buccinator, caudal to the Arcus Zygomaticus. My idea: A small cut through the oral mucosa next to the Molar-Teeth of the upper jaw, accessing the Bichat-Fat through the little gap cranial of the M. buccinator and caudal to the Arcus Zygomaticum. Do you really have to cut through the Buccinator to get to the Bichat? You can get to the Bichat from above the M.buccinator as wel…

What is the difference between white matter and gray matter? What is white matter really? What is gray matter? I don't understand either one... please help me understand this because I have a test tomorrow.

Anyone aware of some whole-body donation programs? I am thinking I will eventually want to donate my body to medical education, but I am unsure of where to start researching something like this. Thanks in advance!

why ESR is higher in females than males? and in pregnants than than not pregnant? and in menstruating than non menestruating? AND THANKS!!!!!!!!!!!!

Hello, I'm looking for studies that show the effect of selective rearing on various brain functions. What I understand by "selective rearing" is the phenomenon by which certain groups of neurons (that is, certain brain centers) develop more fully (i.e. acquire more neurons devoted to performing the function of that group or brain center) when they are stimulated more frequently. As an example, I've heard it said that children who are reared in a music rich environment will be more likely to develop a talent for music because all the music they are exposed to stimulates the music centers in the brain and brings about higher-than-average development of that center. …

If the axillary nerve primarily innervates the deltoid muscle and shoulder area, then why does an axillary nerve block affect the hand and lower arm? Wich nerve block would you use to deaden the deltoids and shoulder area?

I have several questions about the menstrual cycle and would appreciate some clarification. Thanks. 1. Upon birth, a female child is born with primary oocytes. At puberty, primary ooctyes become secondary oocytes. Now it is at menstruation that each of the secondary oocytes are released from the follicle and the whole process occurs. My quest is whether all of the primary oocytes are converted into secondary oocytes at puberty or it is only that primary oocytes start to be converted at each menstrual cycle? I think that the latter is more correct and if so, that means that a female has both secondary and primary oocytes before mensturation. Is there a time or ratio th…

Hello, i want to know if the electrocardiogram propagates from the contracted muscle to other body area!

Hi everyone, I'm new here, but it's an interesting place! I'm trying to find out why humans famously don't like the sound of chalk on a blackboard, knives scraping on plates, nails scraping on plastered walls, etc. The current 'accepted' theories for our reaction are a mixture between an evolutionary defence mechanism (the sounds share properties with animal screams) and the frequency of these sounds being within the range of human speech, hence our ears have evolved to amplify those frequencies. I've embedded six 'nasty' recordings and corresponding edits here - http://helios.hud.ac.uk/u0852268/ If anyone has a few minutes it would be great if you could t…

I am currently completing a peice of work looking at an extra-retinal motion after-effect, after prolonged pursuit of a target in the dark on a black background followed by fixation to a stationary test (measuring MAE). I know that both cortical mechanisms responsible for pursuit and subcortical mechanisms responsible for optokinetic nystagmus are responsible for the MAE. However, I want to know how smooth pursuit systems can affect the suppression of the OKR response. A few papers suggest extra-retinal mechanisms during smooth pursuit (info about eye-movements) can suppress this but I don't know whether that implies that the subsequent afternystagmus (which is thought …

hi guys i was reading around and found that edta can prevent clotting of blood. i have a glass vial that holds 6mm and i want to fill it with human blood but i do not want it to clot so i got tertasodium edta hoping to prevent it from clotting . can anyone tell me if it will work or how much edta i should add to keep the blood from clotting as long as possible? thanks for the help

Based on what we know about cancer so far what can we use as real treatments for cancer/cancers? We know that a "crazed" cell does not get eliminated and begins to reproduce/spread among the area and in malignant cases infects tissue of an organ. We also know that better hygene/health habits such as eating and exercise can reduce your chances for this "crazed" cell from appearing in the first place. Other than our current western treatments lets try and see what we can produce outside of that to slow down, stop or prevent it from happening in the first place. Here is the wikipedia link for more information. Oh yes and other links to more information are much ap…

Concussions just seem to kill you unnecessarily, why would your brain "have" to swell up to the point where it kills itself? It seems like such a trait wouldn't have survived for this many thousands of years.

In a compartment model (in which two chambers are separated by a selectively permeable membrane), equal amounts of KA (organic anion) and NaCl are added to opposite sides. Assume that K+ and Cl- are permeant, and Na+ and A- are not. At steady state, what would the relative distributions of ions be? Would there be a voltage difference between the compartments, and if so, which side would be negative? Would the osmotic pressure (number of solute particles per unit volume) be relatively balanced?

Hi. I have been searching the interenet for possible reasons why essential fatty acid supplements effect my brain. Im talking about borage oils, flax seed oils, fish oils, ect ect. I have tried combined or one at a time and have tried cold pressed and pill forms. A little background. I have a very sensitive pituitary gland. About 4 years ago I had a pituitary tumour removed. I am familiar with many different types of headaches(sinus, pressure, meninjitus, eye pain, ect.). My pituitary is a little more sensitive now I believe(ie. I cant drink as much anymore without getting headaches.. as in I believe I am more likely to get headaches fro…

Are there other phenomena known in neuroscience such as phantom limbs where the brain seems to have a misconception about what is true and it results on psychological or physiological effects? I'm looking for names of these conditions or case studies or anything that I can research. If anyone knows any documentaries on this subject that would be great, too.

I think there has been topics like this before but slightly different... I'm trying to find the main area of the brain that is linked to imagination. What I mean by that is, our everyday life style e.g. places we go / designs we see (clothing of shops etc.) / and even thinking of Heaven, looking at flowers and maybe even also occasions like Halloween. Our general visual perspective. As I have read that the occipital lobe is an area that affects our sleep / dream state. Also the Thalamus relating to visual interpretation and consciousness. But I am trying to pin point very specifically ! As above, people are either grounded in vivid reality or very imaginative with…

I should probably try searching with Google more, but I like to ask people questions... Since I noticed that a large number of Schizophrenia & Bi-Polar patients have enlarged Ventricles in the MidBrain area. I'm trying to narrow down on what the affects of this itself has on patients with Schizophrenia etc. Is there any helpful info on this subject ? More specifically, if there is any affect on the neurons

Hey guys, Due to a recent accident, I've gotten a black eye and a muscle in my neck has become increasingly bothersome. The only way to make the pain stop is to set my head to a 45 degree angle to the right. On top of that, I find it increasingly difficult to walk in a straight line (as in, straighter than normal). I find myself loosing my balance on my right foot (note that I hurt my right eye, related?) and I'm running into door frames and people daily. Can someone elaborate on this? Is it temporary? Thanks! ~Bonez

What does everybody know about ketosis....http://en.wikipedia.org/wiki/Ketosis...I have been sent by Bob to proclaim this word.

Hello everyone, this is my first time to post a topic over here, anyways, I'm a master student and I'm supposed to do Astrocyte primary culture from mouse cortex (mice p2-p5), I've tried it today for the first time and I ruined off the experiment, I guess all the cells that I got were dead already or they died from incubation in trypsin, I'm not actually sure. I do have several protocols for that but I wish if someone is using a specific protocol that is good and works to inform me about it and please from the very beginning as I still have problems with separating the cortices from the pups. Thank you.

I made a 3d model of an MRI for school, and this image is my result. The brain is cut in half, showing the different densities with the colors. Could someone explain to me what this image is teaching, or could teach, if it were labeled in some way? I am not very smart when it comes to anatomy, so this whole thing is a learning experience for me.

If stem cell research was legalized to allow its fullest potential, could there be a possibility of repairing missing limbs?

Dear All , A very Happy Darwin Day to all.On this day I would like all of you to introduce with the fascinating world of Darwinian or Evolutionary Medicine. Evolutionary Medicine is all about understanding the evolutionary origin of diseases , understanding the selection forces that have shaped those traits.The field is emerging like anything and due to the constant efforts of the founders evolution will soon be part of Medical Curriculum in USA.I would like to share my brief write up on Evolutionary Medicine with you all : INTRODUCTION: Darwinian Medicine which is the synthesis of two different disciplines of Evolutionary Biology and Medicine is emer…
