Twitches, starts and other body oddities ....

Just Cutting and pasting to keep you all amused...

Some odd things that go on in our bodies...


Twitches

We are all a little spastic sometimes, and there’s nothing to make you feel more like a spazz than the uncontrollable twitch of an eye or a thigh or a thumb. These little jumps under the skin, called fasciculations, are not well understood but apparently result from nerve abnormalities, which in turn trigger a response in muscle groups associated with that nerve. Caffeine, stress, lack of sleep and even healthy exercise can prompt fasciculations. You can get a twitch just about anywhere you have a muscle, and it’s not uncommon to feel them—and see them—in a calf, in the small muscle between the thumb and forefinger, or in the tongue.

Ear wax

Skin inside the ear is lined with cerumen glands, which are similar to sweat glands except that they excrete wax. The wax coats the walls of the ear canal and traps dirt on its way through, not entirely unlike a Roach Motel.

The wax usually works its way out of the ear naturally, taking the trapped dirt along with it, but sometimes it builds up. There are several home remedies and wax-irrigation products, but if your problem is getting sticky, consult a doctor. The process known as “ear candling,” where wax is heated and drained, is not recommended and makes for very gross candles.

Funny bone

Smacking the so-called funny bone is amusing only to other people. The pain and numbness that follows is due to hitting the ulnar nerve, which is protected by nothing other than a thin layer of skin where it passes around the outside of the elbow. The same nerve gives sensation all the way down the arm, and if you press on it hard enough you will feel your pinky and ring fingers go numb.

Toe cheese

Toe cheese is named for both its fetid smell (c’mon…you smelled it) and the white, cakey glop reminiscent of the crumbled cheese you get on a $15 salad. If the odor is very similar to the aroma of food you’ve been served, you should a) wash your feet thoroughly and scrub between toes, and b) seek other places to dine. The white color is due to the fact that the main ingredient is sock lint, which combines with dead skin, dirt and bacteria. Black, blue and other sock-colored cheeses are common in people who dress a little nicer.

Hiccups

Hiccups are caused by spasms of the diaphragm, and like other spasms they are impossible to turn on voluntarily and troublesome to turn off. The diaphragm is the muscle at the base of the lungs, and a spasm causes a sharp intake of air. The characteristic sound is the glottis (the opening between the vocal chords) closing reflexively. All this can make it difficult to eat, talk, sleep or sneak up on anyone.

Home remedies are based on raising the level of carbon dioxide in the blood (breathing into a paper bag, holding your breath) or stimulating the vagus nerve (drinking water through a washcloth, pulling gently on the tongue, rubbing eyeballs), which runs from the brain to the stomach and may be responsible for the spasms.

Shivers and chatters

Just like rubbing two sticks together creates friction and fire, the body shakes to generate more heat. Shivering hands, trembling legs and chattering teeth are all localized reactions to the body’s attempt at raising the temperature.

Shivers are a common symptom of the flu. Raising body temperature helps mobilize the antibodies that fight infections and viruses, which is why the body also creates a fever.

Brain freeze

No one understands exactly why we experience acute (though short-lived) brain pain from swallowing something too cold too quickly. In truth, the sensation is around our sinuses and face; there are no pain receptors in the brain, so we can’t feel pain there. The ice headache may be due to chilling the trigeminal nerve, which is located near the back of the mouth and is responsible for all sensation to the head and face.

Sleep starts

One moment you’re drifting off to la-la land, and the next instant—whoa!—you’re dropping off a cliff. Sleep experts believe the brain sometimes gets the wrong message from the body during the transition into sleep, and associates the lack of muscle tension with being in midair. Arms and legs then jerk suddenly as they would to break a fall. Not yet realizing the body is simply at rest, the brain also instantaneously conjures a story to account for the sudden jump, and that’s why we picture ourselves falling, slipping or missing a stair.

Jumping when startled

A useful leftover from our primal fight-or-flight days is how we instinctively defend ourselves from unforeseen conflict in a split second. The body prepares to deal with a threat in several ways before the brain even has time to assess the situation. When surprised, we instantly distance ourselves by jumping away and facing the threat. Muscles stiffen and we steady our feet in a fighting stance. Adrenaline surges, increasing our strength, speed and heart rate. Other reactions to sudden fear or surprise include widening of the eyes, clenching of the fists and jaw and, in men, the retreat of genitalia—kind of a “first things first” response.

Hair standing on end

Each hair on your body is held in place by a follicle, which is like a tiny tube in the skin. Sometimes, in response to fear, cold or even a light touch, muscle fibers connected to the follicle contract and cause the follicle to stiffen—making the hair in there stand up straight. Now imagine hundreds of those little follicles standing up straight and what do you have?

Goose bumps

This little body oddity is most likely another component of the fight-or-flight response, but no one is sure what good it actually does. If something intends to eat you, it probably won’t be stopped by the sight of a thousand tiny hairs standing on end. Although, it works for porcupines.

white, cakey glop

That's all I got to say about that!!

Okay, back to discussing the thread.

Two words, one common office item.

PAPER CLIP

Then a day or so later when the wax has partially hardened you use it on the document that you forward to the jackass in the office down the hall.

Nice C&P Jack, here's a site with a list of more interesting/useless body info...

I have no idea why it is in my favorites list.

Thank you. I've always wondered about this one.
But if the body is sending wrong messages, what
else is it getting wrong? :?

In your case, continued breathing.

Thanks!! I put in my favorites, too, just in case Jeopardy calls!

but it's not entirely true....

RE: Babies are born without knee caps. They don't appear until the child reaches 2-6 years of age.

That's not really true..,
Kneecaps form about the fourth month of fetal life. However, they don’t show up on x-ray very well because they’re not ossified, or bony. At this point in life, the kneecaps are made of a cartilaginous material. The growth centers surrounding the kneecap form late in developmental life in utero and may not appear until just before or just after the infant is born.
they don't ossify (become bony) until age 3 for girls and 4-5 for boys!

I still appreciate the link.... It's more of a mythbusters site for me!!

It does'nt happen that often, but I hate it when it does.

Absolutely brilliant post.

Good call Goobs, I'm gonna nominate it for HPOD. If it wins you get a nice fruit basket.
