What are some common ailments of the nervous system?

Mobile Phones
Medical Terminology
Nervous System

What is vasomotor tone?

Constant level of nervous stimulation to the muscles in the blood vessel walls. This gives the muscles a resting level of contraction.

What is permissive action as in the nervous system?


Endocrine System
Nervous System

How fast are hormonal responses?

Slower than nervous responses.

Varies according to what hormone, for example the hormone epinephrine (adrenaline) works almost instantaneously to initiate increased mental alertness among other things. Some hormones take longer to take effect but most take action relatively quickly seconds -> hour

Nervous System

Do animals without a brain feel pain?

NO They don't!

No. People who's lost sensation in their limbs actually feel no pain in them, analysis shows that it's because the nerve connections have been severed from the brain.

Nervous System

Is nervous tissue avascular?


Avascular means that it does not get blood.

Medication and Drugs
Nervous System

Is Xanax a stimulant of the central nervous system?

Its a depressant.

Well, the individual that answered before pretty much hit the nail on the head. I will add some detail to the answer. Xanax is the trade name of alprazolam tablets, developed by Upjohn (Pfizer made the acquisition, so Pfizer produces the Trade name tablets). I will just use Xanax when referring to alprazolam.

Xanax is a benzodiazepine, it is related to Valium, Ativan, and Klonopin. Xanax is used generally treat anxiety disorders and it is the most written prescription for benzodiazepines in the United States. It works well for reducing intense anxiety for example, panic attacks, anxiety attacks, and generalized anxiety disorder some cases. Benzodiazepines have largely replaced barbiturates, which were used prior to the advent of benzodiazepines. Benzodiazepine safety profile remains far superior barbiturates which is why they have largely replaced them. However, it is not stimulant of the central nervous system unless also paradoxical effects occur.

How do natural systems move toward entropy?

Basically everything will reach an equilibrium, and homogeneous mixture of "everything", if given enough time. Living systems stay living by maintain a specific range of disequilibrium within its components (for the most part). The 2nd Law of thermodynamics states basically that temperature, pressure, and chemical potential goes into equilibrium given enough time. this equilibrium is entropy, when things become compartmentalized (ordered) its always do to living systems.

Zoology or Animal Biology
Nervous System

Is a nerve an organ?

Yes nerve is an organ of nervous system ., Each nerve is a cordlike structure that contains many axons. These axons are often referred to as 'fibres'. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. Finally, the entire nerve is wrapped in a layer of connective tissue called the epineurium.

Nervous System

How are neurons categorized in the nervous system?

into either motor or sensory

parasympathetic or sympathetic

adrenirgic or nicotinic

Medication and Drugs
Nervous System

Should you take Atenolol for an essential tremor?

Atenolol is an off-label drug prescribed for essential tremor. Currently, there is no FDA approved drug for this movement disorder. There are other treatment options, including other off-label drugs and Deep Brain Stimulation.

Nervous System

What would happen if parts of the nervous system wasn't there?

If you had no nervous system, you would not be able to move, feel any sensation, experience any emotion or thought.

If parts weren't there, for example, the spinal cord, you would lose all physical sensation from your spinal cord down and would have to breath through a respirator. You would not be able to move.

If your brainstem went missing, you'd be dead. This controls heartbeat and respiration.

If your brain went missing, you wouldn't even know you existed.

If your autonomic nervous system went missing, you would be dead because your heart would stand still in your chest.

Is the retina part of the nervous system?

yes it is. it is one of the 5 senses

Nervous System

The cranial nerve responsible for chewing is?

The trigeminal nerve (the fifth cranial nerve, also called the fifth nerve, or simply CNV or CN5) is the one responsible for chewing!

Nervous System

Is oxygen transport a function of the nervous system?

While it is true that the nervous system controls and regulates all the functions of the body, the actual transportation of oxygen throughout the body begins in the cardiopulmonary system, where oxygen is taken into the lungs and oxygenates blood that flows into pulmonary veins going to the heart, and from their it makes a circuit through the body and into the right side of the heart which receives oxygen poor blood, pumps it through the pulmonary circulation to pick up more oxygen, and from there back to the left side of the heart where it starts a new circuit through the veins and blood vessels delivering fresh oxygen to the body's cells and organs.

Nervous System

What would happen if the heart did not have nerve tissue?

The muscles in the heart respond to an electrical stimulus to contract (beat). If there were no nerve tissue, the heart would not beat and a person would cease (or fail) to exist. Failure of the nerve stimuli, if nerve tissue is there (but for whatever reason there is a malfunction of the signal getting to where it needs to be), results in a condition called "Heart Block" and that can necessitate the implantation of a Pacemaker to produce the missing electrical stimulus constantly or intermittently as needed.

Conditions and Diseases
Nervous System

What diseases affect the nervous system?

Alzheimer's Disease is a degenerative brain disease. It ultimately results in loss of brain function. Victims may have a short attention span, memory problems, and a change in personality.

It can lead to death if at one of the last stages.

Amyotrophic Lateral Sclerosis (Lou Gehrig's Disease). ALS controls voluntary muscle movement


Bell's palsy

brain abscess

brain tumor

Broca's Aphasia

Cerebello-Olivary Degeneration of Holmes

Cerebral Palsy: Loss of muscle control and coordination. A motor disorder. Could be caused by injuries when victim was a baby while his/her brain was developing.

Choroid Plexus Papilloma

acute confusion (one of the most common metal disorders in the elderly; a disturbance of the brain caused by physical illness elsewhere in the body)

diabetic neuropathy

epilepsy (neurons occasionally malfunction and begin to fire together over and over, disrupting ordinary cerebral processing and causing unconsciousness or convulsions; can usually be controlled with medication)


Guillain-Barre Syndrome

Huntington's Disease: An inherited disorder. Loss of neurons that release acetylcholine and GABA. One symptom is chorea, which is involuntary rapid jerky movements. Mental deterioration also occurs. Death usually occurs 10-20 years after first symptoms.

Klüver-Bucy Syndrome

Locked-In Syndrome


Multiple sclerosis is so-named for the multiple sclerotic lesions on the axons of neurons. In the central nervous system, multiple sclerosis attacks the myelin sheath of the axons, affecting the ability to conduct action potentials. Various effects of multiple sclerosis include muscle weakness and spasms, ataxia, dysarthria, chronic pain, etc. This chronic disease can affect young and middle-aged adults.The course of this illness usually involves recurrent relapses followed by remissions, but some patients experience a chronic progressive course. The underlying cause of the nerve damage remains unknown. Multiple Scerosis affects different parts of the brain and spinal cord, resulting in typically scattered symptoms. These can include: Unsteady gait and shaky movement of the limbs (ataxia); Rapid involuntary movements of the eyes (nystagmus); Defects in speech pronunciation (dysarthria); Spastic weakness and retrobulbar neuritis (= inflammation of the optic nerve).

Myalgic Encephalomyelitis (ME) A condition characterized by extreme disabling fatigue that has lasted for at least six months, is made worse by physical or mental exertion, does not resolve with bed rest, and cannot be attributed to other disorders. Unknown.Often occurs as a sequel to such viral infections as glandular fever. Extreme disabling fatigue that has lasted for at least six months, is made worse by physical or mental exertion, does not resolve with bed rest, and cannot be attributed to other disorders. The fatigue is accompanied by at least some of the following: Muscle pain or weakness; Poor co-ordination; Joint pain; Sore throat; Slight fever; Painful lymph nodes in the neck and armpits; Depression; Inability to concentrate; General malaise.

Neuralgia Maybe due to previous attack of shingles (Postherpetic Neuralgia). A severe burning or stabbing pain often following the course of a nerve. Neuritis A disease of the peripheral nerves showing the pathological changes of inflammation. (This term may also be less precisely used to refer to anydisease of the peripheral nerves, usually causing weakness and numbness.) Inflammation of the nerves, which may be painful.

Parinaud Syndrome

Parkinson's Disease Degenerative disease process (associated with aging) that affects the basal ganglia of the brain. Associated with a deficiency of the neurotransmitter dopamine.Also associated with aging. Tremor, rigidity and poverty of spontaneous movements.The commonest symptom is tremor, which often affects one hand, spreading first to the leg on the same side then to the other limbs. It is most profound in resting limbs, interfering with such actions as holding a cup. The patient has an expressionless face, an unmodulated voice, an increasing tendency to stoop, and a shuffling walk. Parkinson's degenerates the nervous system slowly. Parkinson's Disease: Results from damage to the basal ganglia. Neurons that release dopamine degenerate in Parkinson's Disease. An imbalance of neurotransmitters occurs. Symptoms include tremors, rigidity of facial muscles, slow movements, and short steps while walking.

Pituitary Adenoma


senile dementia (disorder which results from the slow process of natural nerve cell loss; may become noticeable between the ages of 70 and 80; although the dementia begins with recent memory, it may gradually) continue until the person forgets his relatives and even his own name

Shingles: Acute infection of the peripheral nervous system. It is caused by herpes zoster (the chickenpox virus). When a person gets chickenpox and recovers, the virus doesn't die off. Instead, it "hides" in the dorsal root ganglion. When the virus reactivates, and the victim has a weakened immune system, it leaves the ganglion and travels down sensory neurons to the skin. It then causes a line of blisters and pain.

spinal cord injury

spongiform encephalopathy

syphilis (late stage)

tetanus (also known as lockjaw because severe spasms of the jaw muscles make it hard to open the mouth)

Tourettes' syndrome is characterized by recurrent and uncontrollable twitches and/or movements
