A branch of neuroscience that studies the physiology of the nervous system. From the Greek words nerve and nature, this science looks at the way that nerves function.
Bring microbes and turn into a source for the production of nitrogen
Burning pain is legs are common because of continuous workout aftera long time. This burning sensation is often at the top part of your thigh .This pain could sometimes be unbearable and the most easiest andlikely to relieve the pain is by keeping an ice pack. or running absolutely hot water on the...
In my opinon it would be Micro Naps, Narcolepsy, and sleepwalking. (I suffer all of these due to constant NightTerrors.) MicroNaps- You fall asleep with out warning or control. Only last about a minute. You confuse reality and your dreams big time. Dangerous if your driving or operating machinery. ...
Opening of sodium channels and the fact that potassium channels arestill closed leads to rapid depolarization that may lead to theneuron firing.
The Circle of Willis is a circle of arteries that provides main blood supply to the brain and the surrounding structures. It is important as prevents ischemia(shortage of blood to tissues) thus preserving cerebral perfusion when one or more artery in the brain is blocked due to throbosis or...
It is called moyamoya and it an extremely rare genetic condition.
In myelinated axons, the voltage gated sodium ions are located along the nodes of Ranvier, the exposed places between the myelin segments. The gates here, however, are not particularly more concentrated than on other un-myelinated axons. TRUE
The entire brainstem is required for life.
There is no specific lowest level of metabolism.
Yes, girls do mature just a bit earlier than boys. Nature provided females with this little boost for the purpose of caring for their young. It does not mean that females are better than males, or that females are smarter than males, it means that females are better suited to ensuring the survival...
Comprised of the brain and spinal cord . The nervous system is the key to homeostasis. The nerves are what keep your body in proper working order and all of those nerves stem from your brain through your spinal cord to reach its destination, then the nerves return to the brain the same way....
When an action potential reaches the end of a neuron, it triggersthe release of neuotransmitters such as epinephrine (sympathetic)or achetylcholine (parasympathetic).
The part of your brain that moves your muscles is called the frontal lobe. The frontal lobe sits behind your forehead and controls your muscles and movement. It is also involved in you behavior and emotions.
It has to do with what types of channels are open during this phase. In the repolarization phase the number of potassium channels are increased and the number of sodium channels are decreased. This allows for action potentials to not occur. Otherwise, the action potentials would add up and produce...
It doesn't, it causes the opposite: a depolarisation block, which is why is used as a muscle relaxant in some circumstances. It may be that your recording electrodes were near a cell where curare had not yet diffused to. Or it may be related to disinhibition from blocking interneurons that express...

A large group of neurons working together is called a brain. A smaller group is called a ganglion.
This occurs due to temporary lack of blood flow, most often due to pressure on the arm - such as while sleeping. The "pins and needles" sensation produces awakening (or lightening of sleep) such that positional changes are made in order to return blood flow to that part of the arm and shoulder.
the 6th sense is a scary movie. Emily Osment's older brother is in that movie, but it was when he was a little kid. the movie is about a little boy and his mother having a 6th sense, which is being able to see dead people.
you would have to be a high level thinker
Prompt medical care can be extremely helpful in cases of stroke (since there is a drug that can dissolve blood clots in the brain). If a person appears to be having a stroke, he or she should be taken to a hospital immediately.
no but rarely they have som but they disappear after it effects the human spinal cord and the brain about and they could affect even higher to .so that is the conclusion of the of mabye the right answer
It is the traveling of the electrical signal down the length of a neuron.
firmly bound to neural tissue and deep to the other meninges. =D

Action potential reaches the action terminal of a nerve cell. This triggers calcium gated ion channels in the axon terminal to open, calcium rushes in. This causes vesicles filled with neurotransmitter to fuse to the membrane and dump the neurotransmitter into the synaptic cleft by exocytosis.
Inflammation of the intercostal bundle, which is the artery nerve and vein. It is a rare condition but can be treated with many alternative treatments such as acupuncture, acupressure, ice and chiropractic care.

Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.
Well smoking crack will make you do that and certain medical conditions will make your ams and legs twitch like that such as jackass syndrome, retardalitus. Hope you get the treatment soon it can become permanent.
Wernicke's area , also known as Brodmann area 22 , is a cortical region within the left temporal lobe of the brain that is associated with understanding speech. Lesions of this area, as is sometimes seen in some strokes, can result in an inability to understand speech even though hearing is...
The change in membrane potential returns to the original negative value of its resting membrane potential.
Cervical neuritis is where you have pressure on the nerves that come out of the cervical spine with is neck area of the spine. The following symptoms will be experienced in one or both of the arms. The main symptoms of neuritis are . tingling and burning sensation . stabbing pains in the...
At present, neurotransmitter depletion (or underfunctioning) is inferred. There is no reliable test for this. Serum levels of various neurotransmitters can be obtained, but they carry little meaning (since their values are not correlative with symptoms and/or conditions/diseases).
The lower extremities are most easily and readily affected. The foot drop from cerebral palsy and Parkinson's Disease, and the neuropathies from diabetes and alcoholism all affect the lower extremities before any other part of the body.
No, technically the striatum is composed of the caudate, putamen, and nucleus accumbens. The lentiform nucleus is composed of putamen, globus pallidus
The hippocampus is a major part of the brain. It is part of the limbic system, and supports long term memory and spatial coordination.
because the chemical message takes a while to diffuse
The olfactory bulb is a small , match-head sized organ in the top of the nasal cavity,and is connected to hundreds of olfactory hairs, or cilia, which lie in a layer of mucous. These have receptor sites, and it is still not well understood how these work, but one theory is that the shape of the...
The autonomic nervous system performs this function, with central control emanating from the brainstem.
By a release & subsequent diffusion of chemicals called neurotransmitters across a very small gap between neurons, called a synapse . How neurotransmitters are released: As an impulse reaches an end of a neuron, called an axon terminal, the impulse opens ion pores in that axon terminal which...
Yes, in a manner of speaking. The brain is divided into two hemispheres, right and left. People tend to have a dominant hemisphere which is what also drives their being right or left handed. People who have a dominant right hand (e.g., it is the one they write with and eat with), have a dominant...
No, it uses [highly specific as opposed to bulk] Active Transport Systems times two: one each for each of the 'pumps' - transmembrane Gated Channels are used.
I have optic neruitis and am getting to fly over seas! is it ok to fly with this
Your body gets to hot. If you don't drink ALOT of water, your body runs out of water VERY fast, if you don't drink water. Answer: During extreme heat the human brain that co-ordinates body temperature gets signals from the body to cool & supplies fluids through blood supply that drains out from...
No. When you are born, you have the most neurons you will ever have. Until you are in your early 20's your brain continues to "trim" neurons from your brain, a mechanism that aids in learning and development. After this point, as you age, you begin to lose neurons, simply from age. After brain...
Nobody knows exactly how these drugs help, but the current theories indicate that they act by increasing or decreasing availability of specific neurotransmitters inside the synaptic gap between nerve cells.
The nuclear membrane encloses the genetic material of the cell, and acts as a barrier between the nucleus and the contents of the cytoplasm. This protects the genetic material and allows for regulation.
A neuron is called a inter-neuron because that specific neuron takes impulse from one neuron to a next neuron. For example your sensory neuron sends a impulse that you had felt a hot object. It goes through the spine to a inter-neuron to a motor neuron (this processes is called a reflex). Then the...
Yes, this may be a cause of permanent and severe brain damage. Hypoperfusion means there is an insufficient amount of blood flowing to those parts of the brain. The frontal lobe has neurons that function to regulate emotion and integrate multiple sources of information. The temporal lobes are...
Hello are there online courses you can take to become a neurophysiology technician. What type of courses do you take. How long do you have to go to school.
Acetylcholine is a neurotransmitter in brain, ganglion's of autonomic nervous system, and at post ganglionic nerve ending of parasympathetic fibers. It is also released at motor end plate. After it's release, in synaptic cleft, it transmits the nerve impulse to next target. Within few milliseconds...
When a neurotransmitter lands on their receptor site, they can either excite of inhibit the receiving cell. To excite a cell, positive sodium ions flow to it, which depolarizes the membrane in a similar way to a nerve impulse. The depolarizing effect spreads through the membrane and only last for 1...
In traditional medicine, enzyme supplements are often prescribed for patients suffering from disorders that affect the digestive process, such as cystic fibrosis, Gaucher's disease, diabetes, and celiac disease.
Nothing stays the same, right? The answer is, of course.
Schwann cells are neuroglial cells that actually cover and insulateaxons. They not only help to spend up nerve transmission, but theyalso feed the neuron.
Damage to the basal ganglia cells may cause problems with one's ability to control speech, movement, and posture. A person with basal ganglia dysfunction may have difficulty starting, stopping, or sustaining movement. Parkinson's disease and other neurological disorders.
As the action potential passes an area on the axon, sodium channels are closed, preventing influx of more sodium ions. At the same time, voltage-sensitive potassium channels open, allowing the membrane potential to fall quickly. After this repolarization phase, membrane permeability to potassium...
That should be treated by an ophthalmologist.
Neuronal Denervation in MS . Denervation hypersensitivity occurs in multiple sclerosis. In multiple sclerosis demyelination of oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system result in disruption of communication between upper motor neurons in the...
Cephalic means the head. The appendages for eating includes the mandibles and two pairs of maxillae. There are also three pairs of maxillipeds that move food towards the mouth.
they form alternate pathways for blood to reach a given body region
Adrenaline (epinephrine) and noradrenaline (norepinephrine) are sympathetic neurotransmitters that: - increase excitatory neurotransmission in the central and autonomic nervous systems - induce vasoconstriction (increasing blood pressure, shunting blood away from the surface of tissues, etc.) ...
Neuritis is a generic term meaning Inflammation of a nerve (neuro=nerve, itis=Inflam.) To be more specific you then put the type or name of the nerve with neuritis. Median nerve neuritis is carpal tunnel syndrome a nerve that runs through your wrist. Ulnar neuritis is a nerve that runs through your...
CIDP can occur at any age. However, the malady is more common in young adults, and in men more than in women. The disorder is rare in the general population.
In pharmacokinetics, it represents: - A bsorption - substance enters blood circulation - D istribution - substance is carried through the fluids and tissues of the body - M etabolism - substance is chemically processed/transformed into one or more other substances (called metabolites) - E...
As the disease progresses, the individual experiences stiff muscles, involuntary movements, problems talking, hallucinations, increased confusion, blindness, and sometimes dementia .
