Interesting Human Body Facts

[BruceD]

I remember reading somewhere that drastic ridging and changes in fingernails is symptomatic of some condition. Saw a pt the other day who had this and it brought it up. Can't remember what it was, but this gal's nail beds were really, really gnarly for about the bottom 1/8" of her nail.

Fingernails can tell you much about a person's health, although obviously not always specific or sensitive for particular diseases.

I wouldn't trust this site for a medical diagnosis since it is a site devoted to "acrylic nail enhancement", but it does have pictures with interesting facts about how some diseases present in the nail/nail bed:

I got it! In fact, you know what they say about a guy with big feet.....

"If he's got big feet and big hands, then he'd better be packing, or else that's one funny looking man. It may be true that the size of the ship doesn't matter, but it takes a long time to get to England in a rowboat."

[medicp94dao]

[mikeylikesit]

so the whole thumb thing...i guess the Fonz was just bragging huh?

 

[BruceD]

-Your brain operates on the same amount of power that would light a 10-watt light bulb.

.. Dim bulb?

-Human thighbones are stronger than concrete.

Depends on the direction the force is applied...

-A 13 year old child found a tooth growing out of his foot in 1977.

Teratoma? Hope the kid got checked out.

-Your eyes are always the same size from birth but your nose and ears never stop growing.

Teeth on your feet?

I gotta admit I've never heard of the tooth growing out of a foot thing before, but I guess its rare but real... I wonder if he remembered to floss? lol
Anyways heres some more intereting facts from http://www.raybromley.com/guf/humanGUF.html

No one knows for sure why we sleep.
(Isn't it because we need to allow our bodies to regenerate?)

Hair and nails DO NOT continue to grow after a person dies.
(Yea, knew that one)

The harder you concentrate, the less you blink.
(Stairing contest anyone?)

You blink about 6 times a minute while reading.
(Depends on how interesting [or uninteresting] the book is...)

Human kidneys weigh about 5 oz.
(Think i've heard that before)

The average person sheds a layer of skin every 28 days (just not in one big piece).
(Heard that one)

Some studies show that a 30 minute nap each day can reduce the risk of heart attack by 30%.
(What about the 3 McDonalds Burgers you had before you took a 30 min. nap while waiting for your call?)

There is no genetic cause of left-handedness; it is not an inherited trait. Statistically, a child is more likely to be left handed if:
the child is male,
the child is one of a pair of twins (although it is rare for both to be lefties),
the child is born to a mother with diabetes, or who is a smoker, or who is over 30.
(Right handed here...)

Compared with right-handed people, left-handed people are:
at least twice as likely to be admitted to mental institutions,
three times as likely to be alcoholic,
four times as likely to have an accident resulting in an emergency room visit,
more likely to have an IQ over 140,
more likely to have an IQ under 70
more likely to have dyslexia.
(We should start polling our pts to see if they are left handed)

Baldness is not caused by hair falling out. All hair stops growing and falls out after a period of time. Even if a person does not cut his scalp hair, each hair will only grow to a limited length before falling out. Every person with a full head of hair loses about 100 scalp hairs a day this way. If the hair is not replaced by a new hair growing in the same follicle, then "thinning" hair and eventual baldness result.


The pupil of a person’s eye dilates about 45 percent when the person is viewing something pleasant.

The human brain is pink, not gray.

There are about ten trillion cells in the human body.

The average person’s skin weighs about six pounds.
(Define average in America...)

When a person dies, the first sense to be lost is sight. Then follow taste, smell and touch. The last sense lost is hearing.

A person who has a heart attack while exercising has a significantly greater chance of surviving than a person who has one while resting. This may be because those who require strenuous activity to bring on an attack have healthier hearts anyway; if rest can cause an attack, your heart probably is in poor shape.

The soles of your feet and palms of your hands contain more sweat glands than any other part of your body.

Human taste buds are less sensitive at higher altitudes.

A human brain is 80 percent water; it contains a greater proportion of water than does the blood

In 1977, a 13-year-old boy discovered a tooth growing on his left foot.
(Wonder if he remembered to floss?)

The gene for six digits is rare, but genetically dominant in humans; if you have the gene, you will have six fingers on each hand.
(Could be a Simpson and have only 4 fingers)

Your heart does NOT really stop when you sneeze (a sneeze takes much less time than a heartbeat).

Red blood cells contain no nucleus when they mature (although they start with one). They are the only cells in the body without one.

The average person is about a quarter of an inch taller at night.
(Huh? I thought it was the other way around? When you sleep doesn't your spine decompress, and you are slightly taller in the morning then at night?)

Your pupils dilate when you see someone you love. They also dilate when you see someone you hate.

Rigor mortis occurs more rapidly if a person is killed in a fight or while under stress.

The typical human body has 70,000 miles of blood vessels.

Alcohol lowers the body’s temperature, but causes dilation of the capillaries which creates the illusion of warmth.
(Tequila!)

It is impossible to sneeze with your eyes open.

One of the symptoms of asthma is improved hearing.
(Really?)

Research has shown that beer tastes differently if the drinker hears a particular musical tone while drinking it. The tone for optimum taste is different for different beers.

Air expelled during a sneeze travels at about 100 miles per hour.

An average person laughs about 15 times a day.

Tongue prints are as unique as fingerprints.
(That would suck to have to lick the ink pad)

Men without hair on their chests are more likely to have cirrhosis of the liver than are hairy-chested men. Gradual loss of chest hair and armpit hair is a symptom of cirrhosis.

Women are 37% more likely to go to a psychiatrist than men are.
(Hyperchondria?)

People with blue eyes are the most sensitive to light. People with dark brown eyes are the least sensitive.
(dark brown here, and sounds true)

Your left lung takes in less air than your right one does.

Men's hearts beat slower than women's.

Younger women give birth to a larger proportion of boys than do older women.

Adults are more susceptible to death when bitten by a snake than a child is.

The brain uses 25% of the body’s oxygen, even though it comprises only two percent of the body’s weight.

The Neanderthal's brain was bigger than yours is.

A typical person’s mouth produces a quart of saliva a day

And how do they know? Do they ask the dead guy?? lol

 

[mycrofft]

Bossy Cow...

Proximal nail nasties: injury, formerly had artificials on, starvation, fungus.

Oh, and if you were to take a human lung (or is it two?) and split all the tissues so every alveolus etc was spread out, the result would be a terrible mess covering most of a tennis court, and much of it would be microscopically thin.
And slippery.
Unless you smoke.
