how does your nervous system react when you have an injury?

and what happends if your nervous system does not work properly?
It depends on the injury and how extensive, but most common reaction of nervous system when injury happens is seizures. Seizures is brains way of expressing a problem.Seizures are even more likely with head injury, but seizures can be triggered by a number of things (high fever, stress, medication side effects, etc.). The Nervous System may react in many other ways to injury, I just have knowledge and experience concerning seizures!  (+ info)

how does the nervous system work with the respiratory system? How do they work together?

---

Does the respiratory system and the nervous system actually work together?
The nervous system effects every single part of your body. The nervous system consists of every nerve tissue in the body. You have nerve tissue in your fingers to tell you when something is hot or cold, in your stomach to let the brain know to send the impulses that digest food, and in your lungs to tell you when to breathe and how much air to breathe in. There are 3 respiratory centers in the brain that control the respiratory rate.

There are stretch receptors in the lungs that tell the brain that the alveoli are completely expanded and that it is time to stop breathing. Your breathing also controls the acidity of the blood. If the blood gets too acidic, the brain tells you to breathe faster to release carbon dioxide. There are also receptors that tell you when to cough, sneeze, sigh (breathe in deeper), etc.

In addition to all of that, you have smooth muscle (involntary muscle) lining the respiratory tract. The nervous system tells the smooth muscle when to contract and when to dialate in response to various stimulation. There are many, many, many stimuli that cause responses - far too many to go over here.  (+ info)

What do the integumetary and the nervous system have in common?

---

I am 12, and doing a project on human body matchmaking. It's srtof like, a dateing thing, ex.- the immune system likes to fight because it likes to fight off disease. So it would be perfect going with the integumentary, which is protective because it likes to protect the skin from anything that could hurt. I really cannot find anything that would make the integumentay and the nervous system go together. Or any qualitys that it could have. HELP!! I REALLY WANT A GOOD GRADEEE!
Well, the integumentary system is the essentially the skin, which is the largest organ in the body, since it covers your entire body. The nervous system also covers the entire body, so it too is very large. They have that in common.  (+ info)

What body system does brain tumor affect besides nervous system?

---

I have this project and I have to write an essay about a disorder. So I choose brain tumor. I know brain tumor affects the nervous system. I need to write what other system does it affect due to brain tumor and the damage of the nervous system? PLEASE HELP ME!!!! THANK YOU!!
It depends on where the tumor is inside the brain, and whether it's benign or malignant. If it's malignant, it will probably cause the whole body to die unless you have it removed, and even then, it's likely to return. There are many different kinds of brain tumors, and I just mentioned two large categories of brain tumors. I would recommend looking at an anatomy drawing of the brain that's labeled with the functions that each part is primarily responsible for. For example, the pre-frontal cortex is responsible for planning, decision-making, maturity, advanced self-control and emotional self-control, learning from your experience, and inhibition of risk-taking. If you damage this section of the brain, you will have problems with one or more of those things.  (+ info)

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 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

Not all of the mechanisms by which heroin and other opiates affect the brain are known. Likewise, the exact brain mechanisms th  (+ info)
