Is there a relationship between the sympathetic nervous system and extreme sickness?

---

I'm not exactly sure what the sympathetic/parasympathetic nervous system is, but is there any relationship between them and extreme sickness? For example, you eat food that went bad and you feel so sick that you think you're going to die...will either of those nervous systems do anything in response?
The short answer is, yes, the sympathetic nervous system responds to rotten food.

The SNS is geared to mobilize the body's resources under stress, to induce the flight or fight response, and it's contstantly active at the basal level maintaining homeostasis. The sympathetic nerves originate inside the vertebral column toward the middle of the spinal column.

Rotten food sets it off, since the SNS aids in the control of most of our internal organs, including release of neurotransmitters (brain chemicals), dilation of pupils, gut motility and urinary output, digestion, increases renin in kidneys, increases rate and force of heart contraction, releases adrenaline into the blood, and promotes ejaculation in the penis.  (+ info)

What are costs of diagnosing disorders in the digestive system?

---

Investigate and compare the cost of at least three tests used in diagnosing disorders of the digestive system.
I don't know about the costs, but I would think gastroscopy, colonoscopy, and a detailed blood test. (of all 3 , the blood test is cheapest).  (+ info)

What is the influence of music on our nervous system?

---

I read on a book that music cause a negative effect on nervous system, it will reduce the ability of concentration and memory.
Blood pressure and so on... I want just your idea to confirm it or not?
Depends upon the individual and what kind of music. Classical music seems to help. Some classic rock is also beneficial. Very loud heavy metal, well studies with mice have shown that Rave conditions conbined with amphetamine type drugs can kill.  (+ info)

What career should I choose that involve with musketal and nervous system?

What health care careeer should i choose?
I want to do something that is involved with health problems of the musculoskeletal system and treat the effects of those problems on the nervous system and on general health like arthritis, joints, and ect? I was thinking about chiropractic but they have their different method, so I'm trying to find a different career EXCEPT chiropractic. What should i choose?
There are many different health career options, depending on how ambitious you are and how many years you want to be in school and training. Physical medicine and rehabilitation (PM&R) is a career in the field of medicine, and requires an M.D. degree. ECT is a treatment used in psychiatry, another career in medicine. There are some neurologists who specialize in spine disorders. There is also physical therapy and occupational therapy, acupuncture, accupressure, and massage therapy.  (+ info)

How does heroin affect the central nervous system?

---

How does heroin affect the nervous system, like memory, mental health etc. And what is the effect? Thank you!
Heroin Effects
Heroin effects the central nervous system by depressing it. Heroin depresses nerve transmission in sensory pathways of the spinal cord and brain that signal pain. This explains why heroin is such an effective pain killer. Heroin also inhibits brain centers controlling coughing, and breathing.

Heroin is exceedingly addictive, quickly producing tolerance and dependence. Although heroin is even more effective as a painkiller than morphine and codeine, it is so highly addictive that its use is illegal. Methadone is a synthetic opiate that is used to break addiction to heroin (and replace it with addiction to methadone).

Short Term Heroin Effects

Soon after injection (or inhalation), heroin crosses the blood-brain barrier. In the brain, heroin is converted to morphine and binds rapidly to opioid receptors. Abusers typically report feeling a surge of pleasurable sensation, a "rush." The intensity of the rush is a function of how much drug is taken and how rapidly the drug enters the brain and binds to the natural opioid receptors. Heroin is particularly addictive because it enters the brain so rapidly. With heroin, the rush is usually accompanied by a warm flushing of the skin, dry mouth, and a heavy feeling in the extremities, which may be accompanied by nausea, vomiting, and severe itching.

After the initial effects, abusers usually will be drowsy for several hours. Mental function is clouded by heroin's effect on the central nervous system. Cardiac function slows. Breathing is also severely slowed, sometimes to the point of death. Heroin overdose is a particular risk on the street, where the amount and purity of the drug cannot be accurately known.

* Analgesia (reduced pain)
* Brief euphoria (the "rush" or feeling of well-being)
* Nausea
* Sedation, drowsiness
* Reduced anxiety
* Hypothermia
* Reduced respiration; breathing difficulties
* Reduced coughing
* Death due to overdose - often the exact purity and content of the drug is not known to the user. An overdose can cause respiration problems and coma

Long Term Heroin Effects

One of the most detrimental long-term effects of heroin is addiction itself. Addiction is a characterized by compulsive drug seeking and use, and by neurochemical and molecular changes in the brain. Heroin also produces profound degrees of tolerance and physical dependence, which are also powerful motivating factors for compulsive use and abuse. As with abusers of any addictive drug, heroin abusers gradually spend more and more time and energy obtaining and using the drug. Once they are addicted, the heroin abusers' primary purpose in life becomes seeking and using drugs. The drugs literally change their brains.

* Tolerance: more and more drug is needed to produce the euphoria and other effects on behavior.
* Addiction: psychological and physiological need for heroin. People are driven to get more heroin and feel bad if they do not get it. People begin to crave heroin 4 to 6 hours after their last injection.
* Withdrawal: About 8-12 hours after their last heroin dose, addicts' eyes tear, they yawn and feel anxious and irritable. Excessive sweating, fever, stomach and muscle cramps, diarrhea and chills can follow several hours later. These withdrawal symptoms can continue for 1 to 3 days after the last dose and can last 7 to 10 days. In some cases, full recovery can take even longer.

Other Heroin Effects

Medical consequences of chronic heroin abuse include scarred and/or collapsed veins, bacterial infections of the blood vessels and heart valves, abscesses (boils) and other soft-tissue infections, and liver or kidney disease. Lung complications (including various types of pneumonia and tuberculosis) may result from the poor health condition of the abuser as well as from heroin's depressing effects on respiration. Many of the additives in street heroin may include substances that do not readily dissolve and result in clogging the blood vessels that lead to the lungs, liver, kidneys, or brain. This can cause infection or even death of small patches of cells in vital organs. Immune reactions to these or other contaminants can cause arthritis or other rheumatologic problems.

Of course, sharing of injection equipment or fluids can lead to some of the most severe consequences of heroin abuse-infections with hepatitis B and C, HIV, and a host of other blood-borne viruses, which drug abusers can then pass on to their sexual partners and children.

* HIV/AIDS - due to sharing of needles
* Poisoning - from the addition of toxin to the drug
* Hepatitis - liver damage
* Skin infections - from repeated intravenous injections
* Other bacterial and viral infections
* Increase risk of stroke
* Collapsed veins
* Lung infections

what makes our nervous system react when we here a loud noise and it makes us jump?

---

What is making our body jump. I mean we don't do that voluntarily. What causes ones body to do things involuntary? Don't just say the nervous system please please explain the process that takes place. Thanks for your answers and God Bless All.
When you hear that loud noise that scares you, a signal is sent to your brain. Then that reacts with you abdominal muscles. This lets out adrenaline. When you let out adrenaline, you get a jumping feeling/stomach feeling or a little jittery feeling. That is the answer to you question  (+ info)

How do chemotherapy drugs affect the nervous system?

---

Hi I need to know how chemotherapy drugs affect the nervous system. And the side affects caused by them on the nervous system.
Chemotherapy adversely affects cognitive function both acutely and chronically, but little is known about the underlying mechanisms. A new study shows that short-term chemotherapy causes not only acute injury to progenitor cells, but also delayed damage to myelin.

Some chemotherapy drugs can cause direct or indirect changes in the central nervous system (brain and spinal cord), the cranial nerves, or peripheral nerves. The cranial nerves are connected directly to the brain and are important for movement and touch sensation (feeling) of the head, face, and neck. Cranial nerves are also important for vision, hearing, taste, and smell. Peripheral nerves lead to and from the rest of the body and are important in movement, touch sensation, and regulating activities of some internal organs.

A few chemotherapy drugs, for example cisplatin or vincristine, can permanently damage parts of the nervous system. Although it is not yet proven, these drugs may interfere with the nerves that control erection.-  (+ info)

What are the effects of stress on the nervous system?

---

My boyfriend was rather stressed by an event, and the event passed everything went great for him but he still seems to be feeling bad even though everything's fine. What are the effects of stress on the nervous system? What can I do to make him feel better?
It leaches calcium from the bones and central nervous system, hence being 'on edge or wired'/

The thing is, you can just support him and get him to relax. He has done what he could; it's really out of his hands now. He just has to trust in himself that things will be okay, and work out.  (+ info)
