What causes ones ear to ring without any provocation? Does it happen in one ear more than another?
What causes muscle twitches?
Both are odd things that we all experience from time to time regardless of age or anything else as far as I know. Are they just part of the human body operations and do certain people get them more than others?
Tinnitus can be objective (the sound, e.g., a bruit, can be perceived by a clinician) or subjective (perceived only by the patient). The sound may be a quiet background noise, or loud enough to drown out all outside sounds. While the term 'tinnitus' usually refers to more severe cases, a 1953 Heller and Bergman found in a study of 80 tinnitus-free university students that 93% reported hearing a buzzing, pulsing or whistling sound. An increasing number of young people are developing tinnitus; as a result, it is sometimes referred to as "the club disease" as many people experience tinnitus or "ringing ears" after attending loud clubs or concerts or using personal stereos at unsafe volumes. Tinnitus has been attributed to a number of other causes.[citation needed]
Tinnitus can also be exacerbated by severe emotional or physical stress and brought on by loud noises (especially when heard in an otherwise quiet environment) and by physical damage occurring to the ear drum, cochlea or nerve.
[edit]
Mechanisms of subjective tinnitus
The inner ear contains many thousand minute hairs which vibrate in response to sound waves. These hairs in turn send signals to the brain which are interpreted as sound. If these hairs become damaged, through prolonged exposure to excessive volume, for instance, then deafness to certain frequencies occurs. In this case, they falsely relay information at a certain frequency that an externally audible sound is present, when it is not.
The mechanisms of subjective tinnitus are often obscure. While it's not surprising that direct trauma to the inner ear can cause tinnitus, other apparent causes (e.g., TMJ and dental disorders) are difficult to explain. Recent research has proposed that there are two distinct categories of subjective tinnitus, otic tinnitus caused by disorders of the inner ear or the acoustic nerve, and somatic tinnitus caused by disorders outside the ear and nerve, but still within the head or neck. It is further hypothesized that somatic tinnitus may be due to "central crosstalk" within the brain, as certain head and neck nerves enter the brain near regions known to be involved in hearing.
    Acoustic neuromas are small, slow growing benign tumors that press against or invade the auditory nerves. If your tinnitus is only in one ear, you should see your physician to rule this one out. An MRI will probably be required for a definitive diagnosis, but one contributor's ENT felt that an MRI wasn't warranted unless frequent dizziness was present. Acoustic neuromas are removable by surgery but involve a risk of hearing loss. Doing nothing should be considered an option by elderly patients since these tumors grow so slowly.
Sorry about the health questions Kitch. You answered the muscle twitch thing OK. With alcoholism being a culprit but not sure if the other posts answer the ? about the ringing.
My friends and I all had both things as kids. Now I still get that ring every now and again. So does my daughter and her friend.
Does anybody else know what I'm talking about?
It comes in all by itself. Usually when it's quiet. And not provoked by a concert or other loud noise. That's a different kind of ringing. You just know that this ring will stay for maybe 30 seconds and then fade away. For me it happens about every 3 months or so.
I think I know what you're talking about. It's a ringing that you hear, but it's like you can tell it isn't coming from anything in the environment. It just becomes noticeable for a bit, then goes away.
I've gotten that ringing from time to time cm - I don't know where it comes from but it seems normal...at least I think I'm normal at times
twitching is probably a good question - JUST LAST NIGHT I had a brief conversation about twitching -we didn't come up with any answers but it's funny that you guys are talking about it today
I get a weird sound/beep/whatever in my ears when I walk past a house or something that has a TV/Radio/ETC on...
Its really weird...
I hate when that happens... and i'm like "did you guys hear a TV?"... everybody thinks im insane, until they actually discover that somebody turned one on, someplace.
You contract the muscles of the scalp around the ears to wiggle your ears. These muscles are called the "auricular" muscles and are attached to the helmet-like scalp tendon both in front and behind the ear. The auricular muscles are fastened to the bones and tissues of the scalp on one end, and to the skin around the ear at the other.
"The same nerve that causes you to smile or frown controls these muscles," says Patrick W. Tank, anatomy professor at the University of Arkansas for Medical Sciences.
Most people can't wiggle their ears because they can't tell the muscles to move. The neurological pathway is a mystery. A medical technician can, however, apply electrodes to the scalp muscles above the ears and make those muscles spasm by sending a small electrical current through the nerves. Then you can feel where the muscles are and tell them yourself to wiggle your ears. Anyone can learn how because the necessary muscles and nerves are in place.
By the way, twice as many men as women can wiggle their ears.
If almonds, pecans, etc "nuts" come from trees, why are peanuts called peanuts when they come from the ground? Shouldn't they be called something else?
and since they aren't 'tree nuts' is that why people tend to be more allergic to them?
Yes. Peanuts, along with beans and peas, belong to the single plant family, Leguminosae. Legumes are edible seeds enclosed in pods. As a group, they provide the best source of concentrated protein in the plant kingdom. While their physical structure and nutritional benefits more closely resemble that of other legumes, their use in diets and cuisines more closely resembles that of nuts
Where do they fit into the food Pyramid?
Today peanuts are classified in the USDA Food Guide Pyramid with meat, fish, poultry, dry beans, eggs and nuts because of their high protein content. However, because peanuts are plant-based, they do NOT contain cholesterol and some of the saturated fat that is found in animal-based sources of protein. In fact, they contain a much higher percentage of the "good" unsaturated fats than saturated fats. Therefore, peanuts have been placed closer to the bottom of both the Mediterranean and the Vegetarian Food Guide Pyramids, in the eat daily category..
Peanuts are a complex plant food, with more than 30 different proteins. Research is underway to identify exactly which proteins trigger an allergic reaction, and why the reaction can vary in severity among allergy sufferers. Peanut allergy appears to be progressive—subsequent reactions tend to be more severe. Other foods which can cause severe reactions are nuts and shellfish.
Does anyone know how to insert a date formula into word? I know how to add a date and to have it automatically update itself to the current date but don't know how to set it up where you can have it automatically update for a date in the future. '=today()+16' works in Excel but not word. Ideas?

Why is a stop sign red? When sunlight beams down on the sign, all the colors of the spectrum are hitting the red paint. All of the colors are absorbed by the paint, except for red, which is reflected and that's the color our eyes perceive. Green-colored grass absorbs all the colors of the spectrum except green, which it reflects and we see grass as green. Write this lesson on a clean blackboard and we see the white-colored chalk marks as white because the chalk reflects all the colors of the spectrum back to our eyes while the blackboard absorbs all the colors, reflecting none, and we see the absence of any color as black.
Stop signs originated in Detroit, Michigan in 1915. The first had black letters on a white background and were somewhat smaller than the modern one. As they became more widespread, a committee supported by the American Association of State Highway Officials (AASHO) met in 1922 to standardize them, and it selected the octagonal shape that has been used in the U.S. ever since. The unique eight-sided shape of the sign allows drivers facing the back of the sign to identify that oncoming drivers have a stop sign and prevent confusion with other traffic signs.
In 1924, the sign changed to black on yellow, the predominant color scheme until 1954. Another competing group, the National Conference on Street and Highway Safety (NCSHS), simultaneously advocated an even smaller, red-on-yellow stop sign. All of these signs were typically mounted only two or three feet above the ground.
These two organizations conflicted but eventually combined into the Joint Committee on Uniform Traffic Control Devices, which in 1935 published the famous Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) detailing the stop sign's appearance. The MUTCD stop sign was altered eight times between 1935 and 1971, mostly dealing with its reflectorization and its mounting height; the most drastic change came in 1954, when the sign gained its white-on-red color. Red is also the color for stop on traffic signals, unifying red as stop signal for drivers worldwide.
Although already widespread, use of the MUTCD stop sign passed into law in the United States in 1966. The mounting height reached its current level of 2.1 m (7 ft) in 1971. They were later adopted by the European Union as part of its effort to standardize road travel across member countries.
we were just in the bathroom (yes the one thats haunted here on the 3rd floor) but thats besides the point .....
why do women have to go to the bathroom so often? and why does my pee smell like coffee in the afternoon? and how long does it take for something you drink to come out the other end?
The smell produced by asparagus is unusual in that it is utterly different from the vegetable smell (whereas coffee and spice odors are unchanged by passage through the body).

how many of you guys can wiggle your ears?
<raises hand>
wow...that Might have been the fastest research on an "Ask Kitch".

I was thinking more along the lines as 3M but you made me feel a bit more sane. :smile:
and since they aren't 'tree nuts' is that why people tend to be more allergic to them?
not sure...but I'm going to ogaras in a bit to do some research...
that and I left my credit card there...

I like the name goober
huh. Guess I'm smarter than I thought.
xo
S
why you ask?
because... you cant beat "off with no hands".
and I don't wanna "research" it...
I know how to add a date and to have it automatically update itself to the current date but don't know how to set it up where you can have it automatically update for a date in the future
heh!!!

why do women have to go to the bathroom so often? and why does my pee smell like coffee in the afternoon? and how long does it take for something you drink to come out the other end?
hmmm....I heard you wanted another one :wink:
I'd worry only if your coffee smells like pee.
and it can take up to 12hrs in your system...
