Ok, so I was eating dinner with a friend of mine and we came up with some pretty strange ideas. How bout some help discerning them....

1.) What do you call a quadrapolegic (sp?) that is for some reason, missing a limb? Are they a triplegic???

2.) Ok, here's a strange scenario. Suppose your parents get divorced. You start dating someone and eventually get married. If one of your parents (i.e.: your mother) begins dating your spouses parent (i.e.: there father) and get married, does that mean you are married to your step sister (or brother)??? What the hell kind of family is that!?!

For the record, neither of these "strangeties" are parts of my life. Just strange thoughts... http://forums.murc.ws/ubb/smile.gif

I know, I know! OK, I can't help it, so here it is:

1. A very ****ed up triopelegic. Hell, he's almost a parapelegic again.

2. A seriously dysfunctional family that belongs on the Jerry Springer show.

Excuse my burtish manner, but isnt a quadraplegic someone who is paralized? who ever said anything about losing more than 4 limbs?

Besides, as far as I know, qudraplegic refers to the condition, not necesaraly to the amount of limbs the person has. You can be missing a leg and still be a quadra. Like if your in a accident where your paralized and lose a limb. Get it?

Finally, the family thing? As long as there is no blood relation, there isnt a problem. The only reason everybody has these taboo's against incest is for genetic well being. SO no genetic relation (well, directly) and no problem.

Simple dont ya think?

Zeg FaRaN, zit Dimi effe niet te pesten door Nederlands te schrijven, als z'n vrienden het lezen is-ie ze weer kwijt. Trouwens, hij verstaat er geen klap van... oeps http://forums.murc.ws/ubb/wink.gif

Dimi, I didn't miss you on ICQ this weekend asking me "why the fori were down", "when the fori would be back", "if I contacted Ant about it" and if so, "whassup?" http://forums.murc.ws/ubb/wink.gif

Being the FAQ mod is a difficult job, when the fori are down http://forums.murc.ws/ubb/wink.gif

Someone gonna translate that sh*t for us Americans???

Genom, I wasn't thinking there would be a problem with the family thing, I was just thinking it would be funny if you went to a party or something and you had to introduce the spouce. Wouldn't it be something like, "This is my wife ... er, and ... er ... step-sister... um, I'm gonna go now...." http://forums.murc.ws/ubb/smile.gif

Jord, I'm sure if I checked my ICQ history, I would find more than just "why the fori were down", "when the fori would be back", "if I contacted Ant about it...." It seems to me it might be time to get a memory upgrade....

Quadriplegia is the paralysis of all *four* limbs, typically from spinal cord injuries or stroke. I don't think it has anything to do with amputation, but it always involves four limbs. The first syllable, "quad," is significant. Genom is correct. Someone paralysed from the neck down *and* missing a limb is considered quadriplegic, as they lost or never had the use of all four limbs.

if a quadrapleigic has lost four limbs then how can he/she loose an other?
Unless it is some god damn inbread freak.

Ahem...
Anyone want an educated opinion? http://forums.murc.ws/ubb/smile.gif

Paul is rigth. Quadraplegia (or tetraplegia) has nothing to do with loss of a member.It is paralisis of the four limbs (and body) usually due to spinal cord injuries in the upper cervical spine (before the emergence of nervous brachial plexus, who gives the motor innervation to upper limbs). Stroke usually doesn´t result in tetraplegia because it would have to be so extense that the poor guy would be dead much after. A stroke usually gives hemiparesia or hemiplegia - the loss of streght or total paralisys on one side of the body, accordingly. That happens when the stroke affects the motor cortex on the brain or a piramidal tract - that is a nervous tract from where come all the motor nervous fibers for one side of the body.

also,
Paralysis results below a spinal cord injury. Quaraplegia
results from cervical injury. Above C1--C2 usually death from inability to breathe. C3-C4 usually needs a respirator for life support. C5-C6: maybe a weak bicep, but nothing else. C6-C7 may have some use of upper shoulders/bicep or some weal tricep. Everyone is slightly different anatomically.
These are known as anomalies. Each injury is slightly different and it is important to know if the anterior or
posterior portions of the cord are both injured, if the injury is a bruise or a break in the spinal cord. http://forums.murc.ws/ubb/wink.gif

Speaking of anomalies, sh*t, you should see my stomack.... Everyone's always talking about they're six/eight pack or whatever, right? Well, I got a 7 pack.... http://forums.murc.ws/ubb/frown.gif It's all crooked and sh*t and the right side (smaller side in case you're wondering) you can't see the lowest muscle - whatever it's called. It pisses me off. I really don't like doing ab workouts because of that (not that it makes any difference whether or not I do, but...).

So, how many of you guys are doctors out there or do you just know crazy anatomy? Not you Patrick, you don't count. You're not officialy a doc yet, right?... http://forums.murc.ws/ubb/wink.gif

Nuno:
Do my Neurology exam for me please?

(momentary lapse of thought)

The damage to your spinal cord would have to be below c3 (phrenic) but above c5 (brachial plexus) right?

What about a bilateral infarct of the internal capsule? (however improbable)

Dimitri,

Yes Patrick, the damage would have to at least partially spare the phrenic (diaphragmatic) nerve but affect fully the nerves to biceps, triceps, deltoids and below. As everyone has slightly different anatomy the exact cervical nerves vary. Just check out your neuro books, btw which ones do you use, I can't even remember which ones I did.

Yes Patrick, a big A+ for you http://forums.murc.ws/ubb/smile.gif
Althought a bilateral infarct of the internal capsule is really highly improbable. For what I´ve seen, a acute cerebral infarct is mainly one vessel dependant (most frequently a MCA dependent). Yes, two consecutive cerebral infarcts could occur, but frankly speaking, usually they result in death rather than anything else.

How is your medical course in there? How many years?

And I realized Patrick is a medical student, but what is your field, DentyCracker? http://forums.murc.ws/ubb/smile.gif

I have a couple of questions:

1. What is the difference between 'acute myelitis' and transverse myelitis?

2. If a limb is considered 'spastic', what are the causes of this symptom? Is it a problem with just an injury to the spinal cord or does it have something to do with some sort of brain damage(ie; popped blood vessel, etc...)? or is it both?

3. What is the longest amount of time it takes for nerves to heal after an accident? I've heard up to 2 years.

Transvers myelitis is an acute (or sub-acute) inflamatory disease of the spinal cord whose simptoms are focal pain in neck, back, parastesic sensations, sensorial loss, motor loss and sfincter abnomalities.
It´s associated with viral infections or even vaccination

1.
As far as i know, acute myelitis is inflammation of the myelin sheaths surrounding neurones. I have never heared of transvers myelitis though.


2.
Signs of Upper motor neurone lesions (spinal cord and nerves)

Muscle weakness (if the lesions e.g. a pyramidal lesions occurs above the decussation) on the contralateral side. For long tract lesion due to spinal damage the weakness may be ipsilateral but more often is bilateral.

Increase in muscle tone (spasticity) because the inhibitory effect of the corticospinal tract is removed. As the upper limb flexors are stronger than the extensors, the arms tend to flex. In the lower limb extensors tend to predominate.
The increase in tone is characterised by changes in the resistance to passive movement - giving a 'clasp knife' or 'cog wheel' effect.

Hyperreflexia: The "damping" effect of the corticospinal tracts upon reflex acitivity in the PNS is removed so reflexes are exaggerated. Flexor reflexes predominating in the upper limb and extensor responses in the legs. In consequence the plantar response of the foot becomes extensor. This means that when the sole of the foot is stimulated the normal plantar flexion is replaced by a dorsiflextion of the foot and a fanning of the big toe (a positive Babinski sign).

Spasticity. Like hyperreflexia, spasticity arise from a loss of an inhibitory effect of higher motor centres.

A positive Babikski sign where the normal curling of the toes and plantar reponse to a stimulus applied to the sole is replaced by an extension of the toes an dorsiflexion of the foot. The sign of Bing is also present, i.e. when a pin is used to stab the dorsum of the foot the normal reaction, to extend the foot away from the pin, is replaced by a flexion which drives the pin into the foot.

Signs of Lower motor neurone lesions (spinal cord and nerves)

Muscle weakness - (paresis)

Muscle wasting

Fasciculation: flickering contractions of a muscle which can be seen through the skin

Areflexia: absence of reflexes

Hypotonia: marked reduction of muscle tone to give a flaccid muscle


3.
As far as i know, the only way a nerve can heal is if the damage occurs to the axon only. If so, then the longest time for a nerve to heal would be directly proportional to the lenth of the axon. The sciatic nerve is the longes nerve in your body, but even then i think that 2 years is very optimistic.
To be honest i dont think anyone really knows.
I have read studies about manipulating germ cells to try and get them to differentiate into neurones, but i wouldn't hold your breath.
I think that the trick is not to damage it in the first place!
