Course Of FACIAL NERVE

The motor part of the facial nerve arises from the facial nerve nucleus in the pons while the sensory part of the facial nerve arises from the nervus intermedius.
The motor part and sensory part of the facial nerve enters the petrous temporal bone into the internal auditory meatus (intimately close to the inner ear) then runs a tortuous course (including two tight turns) through the facial canal, emerges from the stylomastoid foramen and passes through the parotid gland, where it divides into five major branches. Though it passes through the parotid gland, it does not innervate the gland. This action is the responsibility of cranial nerve IX, the glossopharyngeal nerve.
The facial nerve forms the geniculate ganglion prior to entering the facial canal.

[edit]Branches
Greater petrosal nerve - provides parasympathetic innervation to lacrimal gland, sphenoid sinus, frontal sinus, maxillary sinus, ethmoid sinus, nasal cavity, as well as special sensory taste fibers to the palate via the Vidian nerve.
Nerve to stapedius - provides motor innervation for stapedius muscle in middle ear
Chorda tympani - provides parasympathetic innervation to submandibular gland and sublingual gland and special sensory taste fibers for the anterior 2/3 of the tongue.
[edit]Outside skull (distal to stylomastoid foramen)
Posterior auricular nerve - controls movements of some of the scalp muscles around the ear
Branch to Posterior belly of Digastric and Stylohyoid muscle
Five major facial branches (in parotid gland) - from top to bottom:
Temporal (frontal) branch of the facial nerve
Zygomatic branch of the facial nerve
Buccal branch of the facial nerve
Marginal mandibular branch of the facial nerve
Cervical branch of the facial nerve
A traditional mnemonic device for the five major branches of the facial nerve is, "The Zebra Bummed My Cat." Other mnemonics for the divisions of the facial nerve include, "Today Zoe Bummed My Car", "To Zanzibar By Motor Car", "Tell Ziggy Bob Marley Called", "Ten Zebras Bullied My Cat", "Two Zulus buggered my cat" and "The Zoo Bought Monkey Clothes."

New Alzheimer vaccine to be tested in Europe By AFP - Fri Apr 23, 7:39 AM PDT
VIENNA (AFP) - A new vaccine against Alzheimer's, developed by the Austrian biotechnology firm Affiris, will soon be tested in six European countries, the company announced Friday.

Some 420 patients will be recruited to take part in clinical trials in Austria, Croatia, Czech Republic, France, Germany and Slovakia, Affiris said in a statement.

The AD02 vaccine, developed with British drugmaker GlaxoSmithKline, was already tested for safety and tolerability over the past year.

The clinical trials will now test its efficacy, with results expected as early as 2012, the company said.

ADO2 is meant to prevent the building up of beta-amyloid plaques in the brain, which cause the degradation of nerve cells and are believed to play a crucial role in causing Alzheimer's disease.

The vaccine works by causing the body to attack these plaques by producing more antibodies, Till Jelitto, a spokesman for Affiris, told AFP.

More specifically, these antibodies are meant to attack only the part of the beta-amyloid protein that causes the plaques, he added.

This would reduce the risk for patients, as the protein as a whole already exists in healthy individuals.

The current vaccine is therapeutic, meaning it is aimed at treating patients already affected by the disease. But if results are positive, the technology could also be used to manufacture a prophylactic, or preventative, vaccine, Jelitto said.

In 2001, tests for a first vaccine against Alzheimer's disease were conducted in the United States and Europe but had to be cut short after serious side effects emerged.

Another vaccine was tested in Sweden in 2005.

Alzheimer's disease, also known as AD, is a neuro-degenerative disease that affects cognitive functions, further impacting patients' behaviour and social adaptation.

The disease, which still has no known cure, affects about six million people in Europe every year.

Affiris is also working on vaccines against Parkinson's and atherosclerosis
Spanish hospital claims first full face transplant By DANIEL WOOLLS, Associated Press Writer - Fri Apr 23, 7:13 AM PDT


MADRID - A hospital in Spain said it has carried out the world's first full-face transplant, giving a young man who lost his in an accident a new nose, skin, jaws, cheekbones, teeth and other features.

The operation was carried out by a 30-member medical team in late March and took 24 hours to perform, according to Vall d'Hebron Hospital in Barcelona.

The patient now has a completely new face from his hairline down and only one visible scar, which looks like a wrinkle running across his neck, said Dr. Joan Pere Barret, the surgeon who led the team.

"If you look him in the face, you see a normal person, like anyone else we have as a patient in the hospital," Barret told The Associated Press on Friday.

He declined to name the patient or give details of the accident five years ago in which he lost his face, saying only that he was a Spaniard between the ages of 20 and 40 and is recovering well.

He cannot yet speak, eat or smile, but can see and swallow saliva.

"He is coming along well. He sits up, he walks in his hospital room and he watches television," Barret said.

Barret said there have been 10 partial face transplant operations carried out in the world so far but this is the first involving a person's whole face. The world's first partial face transplant was carried out on a woman in France in 2005. Others have been done in the U.S. and China.

Barret said his team used the same techniques of plastic and microsurgery as in those cases, and simply chose to try for a full-face transplant because the damage suffered by this man was so severe.

Since the accident, the patient has had to breathe and be fed through tubes and had problems speaking. Before this, he underwent surgery nine times.

A week after the operation, the patient asked to look at himself in the mirror and was satisfied with what he saw, Barret said.

The patient underwent psychiatric tests before the operation to determine if he would be able to confront having a totally new face, the hospital said.

He is expected to remain hospitalized for two months.

Hospitals in Spain have performed two partial face transplants, in Valencia and Seville.

The Brain

The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.

Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
The human brain cell can hold 5 times as much information as the Encyclopedia Britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1,000 terabytes. The National Archives of Britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.
The brain is much more active at night than during the day. Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
Scientists say the higher your I.Q. the more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register.
Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn’t grow or regenerate. While it doesn’t act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.
The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. That doesn’t mean your head can’t hurt. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain and can give you a pounding headache.
80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on TV. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue. So the next time you’re feeling dehydrated get a drink to keep your brain hydrated.
