Does upregulation of insulin receptors occur in neurons just as other cells in the body, if the brain is always receiving a steady supply of glucose?
Our body: Maintained a biological balanced status through a variety of different mechanism. Our heart rate is control by different mechanism. One is the autonomic nervous system. Parasympathetic decrease and sympathetic increase. A well balance o2 delivery: o2 demand will keep hr normal if no other stressors to the body(diseases). ...Read more
What to do if a transplanted heart has no nerve supply, how does the cardiac output of a transplanted heart increase and adapt to physiological changes?
Can't store protein: Unlike carbohydrates and fat, there is no storage form in the body for proteins. Proteins are either incorporated into tissues or they are eliminated. However there are conditions in the body such as amyloidosis which involve abnormal deposition of misfolded proteins; these can cause a variety of problems including heart failure and kidney failure. ...Read more
Brainstem: The regulatory signals for breathing come from the brainstem, located at the back, bottom-most portion of the head. ...Read more
The sympathetic chain is the pathway between the body (all organs and systems in the body), and disrupting it will affect the whole, not just sweating?
It depends...: It depends on what kind of damage (disruption), such as: which nerves, where in the nerves, how many nerves, the size of the nerves, etc... The signals from sympathetic nerves create effects like include pupil dilation, increased sweating, increased heart rate, and increased blood pressure. ...Read more
What will happen to the body's nervous systems & endocrine systems if homeostasis is not maintained?
Dysregulation: If homeostasis is completely lost, the body's nervous system and endocrine system would both become dysregulated. You could see all kinds of metabolic and acid-base problems, with altered mental status (delirium, hallucinations, etc) plus blood pressure changes and more. Thankfully, the body knows exactly how to respond to various conditions, so that homeostasis is dynamic, not static. ...Read more
Gluconeogenesis: Gluconeogenesis is the process of making glucose from other fuels, and your body can do this from protein and fat. Mainly the liver does this. However, it is virtually impossible to eat a diet with "no carbs". Very low carb diets cause excessive ketosis, which causes a lot of symptoms. ...Read more
During heart transplant surgery. How is blood flow kept to the brain since the heart has to be taken out?
Heart lung machine: During heart transplant and in fact many types of heart surgery the patient is connected to cardiopulmonary bypass machine. . The blood is drained out from the large veins (vena cava) into the machine. Oxygen is put into the blood and it is returned into the artery system usually the aorta. So even with the heart stopped, the body and brain continue to receive blood and oxygen. ...Read moreSee 2 more doctor answers
Depends: There are many systems in the body that need to be regulated. For instance, if blood pressure goes too high you can stroke; if there is too much cholesterol, you can stroke or get nerve damage. If the immune system is not under control, the brain and nerves can be damaged. If you have vitamin deficiencies or excess, the nerves and the brain could be damaged, etc. ...Read more
Artificial pacemaker: Artificial (implantable) pacemakers are mostly regulated by a sensor that recognizes motion. It's similar to the sensor that changes your phone/ipads display from portrait to landscape, based on the direction of the device. There are other sensors, such as ones that measure the density of blood in the heart and chest motion (simulating breathing). Get your routine pacemaker maintenance checks. ...Read moreSee 1 more doctor answer
