Cerebral spinal fluid flows from the lateral ventricles to the 3rd ventricle through the____________(what?)?

---

That formed by the plexuses of the lateral ventricle passes through the interventricular formina into the third ventricle. ♥  (+ info)

What is the connection between malignant neoplasms and crabs?

---

The more common term for malignant neoplasms, cancer, is Latin for crab, and the word "carcinogen," meaning a cancer-causing agent, comes from the Greek word for crab, "karkinos." What is the connection between these two seemingly unrelated things?
Cancer, both the disease and the astronomical constellation, derive from the Latin cancer or cancrum, meaning crab. The astrological sign, of course, is said to resemble a crab and the disease was so named by the ancient Greek physician Galen (129-200 A.D.) who noted the similarity between a certain type of tumor with a crab as well—the swollen veins around the tumor resembling the legs of a crab.

Old English adopted cancer directly from Latin and used it for a variety of spreading sores and ulcers. This early sense survives in the modern word canker. From c.1000 in a manuscript called Læce Boc (Leech Book), collected in Oswald Cockayne’s Leechdoms, Wortcunning, and Starcraft of Early England, Vol. II, 1865:

Gemeng wið þam dustum, clæm on ðone cancer.
(Mix with the dust, smear on the cancer.)

And from Wyclif’s 2 Timothy, 1382:

The word of hem crepith as a kankir

The word was being applied specifically to the disease we today call cancer by the beginning of the 17th century. From Philemon Holland’s translation of Pliny’s Historie of the World:

Cancer is a swelling or sore comming of melancholy bloud, about which the veins appeare of a blacke or swert colour, spread in manner of a Creifish clees.

The astronomical sense of cancer is from the Latin name for the constellation of the crab. The name was known to the Anglo-Saxons, but only as a Latin name and was not assimilated into English until the Middle English period. It appears in Ælfric’s De Temporibus Anni, written c.993, in a list of the constellations of the Zodiac:

Feorða • Cancer • þæt is Crabba
(Fourth, Cancer, that is the crab.)

The Anglicized name appears c.1391 in Chaucer’s Treatise on the Astrolabe:

In this heved of cancer is the grettist declinacioun northward of the sonne...this signe of cancre is clepid the tropik of Somer.
(At this first point (head) of cancer is the greatest declination northward of the sun…this sign of cancer is named the tropic of summer.)

How dangerous is an enlarged right ventricle?

---

I have been told that I have an enlarged right ventricle that is also (hardening?) and severe pulmonary regurgitation.
I have also been told I have a mild irregularity in right ventricular function.My regurgitation is about 40% flow back.
I am having trouble with my cardiologist and i'm having to wait to see another one I just want to know how dangerous this is.
you would require surgery for valve replacement and earlier the better.  (+ info)

What does an enlarged left ventricle of the heart do to an unborn child?

---

My friend is pregnant and she had a sonogram today. The doctors said that the baby has fluid on the heart and an enlarged left ventricle.
First, her doctor should discuss this in length with her. Here is a site which may answer some questions:http://www.kidshealth.org/parent/medical/heart/congenital_heart_defects.html  (+ info)

What can happen if the left ventricle to the heart has a blockage?

---

What happens if the left ventricle or left atrium to the heart has a blockage?
If blood cannot pass through the left ventricle or atrium due to some pathology, then blood will dam back into the lungs causing pulmonary congestion. If the lungs become too congested this will put a strain on the right side of the heart which can eventually lead to right-sided heart failure and its attendant signs and symptoms (hepatomegaly, edema, engorged neck veins, etc.). Another consequence of inability of blood to pass through the left side of the heart is weakness and fatigue, since it is the left side of the heart that pumps blood to the systemic circuit.  (+ info)

Why pacemaker paces the Atrial and ventricle in the same time?

---

I just curious why the pacemaker has to pace the Atrial and ventricle in the same time?

If Sick Sinus Symptom or A-Fib happen, why can't just pace the Atrial and leave the ventricle alone?

If the AV node not function, why can't just pace the ventricle and leave the Atrial alone. As everyone knows, some people have A-Fib for few weeks also never mind!
In persistent A-fib atria are not paced as it has no effect in persistent A-fib. If A-fib is intermittent, pacing may prevent it in some cases, especially with multi-site atrial pacing.

Atria and ventricles are never paced simultaneously. They are paced sequentially. Ventricle is paced after a delay. This facilitates ventricular filling by atrial contraction. This is more important in those with stiff ventricles. Normally atrial contraction contributes to only about 15% of ventricular filling. But in a ventricle with difficulty in relaxing, atrial contribution may be as high as 30%.  (+ info)

Can a person with cerebral palsy start to walk on their own if they pratice alot?

---

i have cerebral palsy. i think that i can walk if i pratice alot. the other day i went to store and walk with my walker. now my legs are score and i cant pratice now. how can i make my legs less sore?
In my experience, the only way a person with CP will learn to walk is to learn how to do it with minimal effort. When you use the right muscles, walking should be almost effortless.

Think about it...babies experiment by using different muscles and bending their bodies in different positions until they find the simplest way. We don't consciously think about breathing, we just do it. Walking should be easy, too.

PT is the best way for a person with CP to learn how to do these effortless movements. My son couldn't sit up, crawl, or walk for a long time; much longer than the average child. After 3 years of PT, (age 3 1/2) he took his first steps. Now he's 5 1/2 and walking, running, jumping, climbing etc. We continue PT visits once weekly and he also practices at home.

If you force walking before your body and brain learn the correct "tools" to master the movements correctly, I think you will be putting unecessary strain on your muscles and cause more pain for yourself.

Make an appt. with a good PT that specializes in people with CP. They are out there, and they are VERY good at what they do. Good luck!  (+ info)

What are the challenges of cerebral palsy?

---

I am waiting to be a "Big Sister" in Big brothers, big sisters, and they have a possible match for me. She is a girl with cerebral palsy, and I don't know much about it. I have found info online, but it's very clinical and I just wanted some insight on the condition from real people.

Any thoughts? Anything I should know about?
Basically it is caused by damage to the part of the brain that handles your motor skills and muscle control. It really varies from person to person so its hard to say exactly what challenges someone would have though.

If her CP is more severe she might use a wheelchair or walker, and also it might be a little hard to understand her because the CP effects muscle control for talking too? Also a lot of people with cerebral palsy have this thing that makes their muscles really tense and they move involuntarily. I think thats what the other answer is talking about when she says her friend shakes. People will do stuff like shake or kick/move their arms or legs without trying, its just like signals from the brain so they can't control it?

My sister has pretty severe CP and her legs just kick a little bit back and forth constantly like 24 hrs a day. She uses a wheelchair only to get around (noo walking) and I think people who don't know her usually have a really hard time understanding her unless she talks really slow. She can't write or do much with her hands but she can drive her wheelchair and eat by herself. But also I have a friend with really mild CP and he just walks with sort of a stiff limp and has bad handwriting/fine motor skills, basically he's just a little bit klutzy/awkward when he moves. Like I said, it varies a lot? Maybe someone at Big Brothers Big Sisters could tell you a little more about her before you meet her?

Oh, also it is caused by brain damage but that doesn't always mean the person will have a mental disability too. Some people with CP will be mentally challenged and some will be average and some total geniuses.  (+ info)

How does the temporal lobe correspond physically to the cerebral cortex?

---

Is it a part of the cerebral cortex, or is the cerebral cortex inside the temporal lobe? Or are they totally unrelated?
I probably sound like an idiot to all the brain surgeons here, but I'm just a lowly eighth grader who's lost with her science fair project on memory.
Google only shows the temporal lobe; it says nothing about the cerebral cortex.
suggest you use google and enter "anatomy of the brain"  (+ info)
