Here are some more information for Retina Reflex:

Knowing the peculiarities of some body parts of the newborn ensure a very accurate clinical assessment to detect or differentiate between a healthy child and a sick one.

Eyes

Usually the newborn keeps his eyes tightly closed. It is best to begin the examination of the eyes by observing the lids for edema, which is normally present for the first 2 days after delivery. A mongoloid slant, the lateral upward slope of the eyes with an inner epicanthal fold. may be indicative of Down's syndrome, The eyes should be observed for symmetry and for hypertelorism. The mean distance between the inner distance is 2cm, 3cm or more is considered ocular hypertelorism.

Tears usually do not appear until the first or second month of life. Purulent discharge from the eyes shortly after birth may signify Ophthalmic neonatorum caused by gonorrhea, Chemical irritation or conjunctivitis may appear within 1 hours after instillation of silver nitrate but should last only 24 hours. The doctor carefully notes and records any discharge.

In order to visualize the surface structures of the eyes, the doctor holds the infant supine and gently lowers the head. The eyes will usually open, similar to the mechanism of dolls' eyes. The Sclera should be white and clear. The Cornea is examined for the presence at birth but is generally not elicited unless brain or eye damage is suspected. The pupil usually responds to light by constricting. Absence of the pupillary reflex. particularly by 3 weeks of age, suggests blindness. A fixed, dilated or constricted pupil may indicate anoxia or brain damage.

A searching nystagmus is common after birth. Strabismus is a normal finding because of the lack of binocularity. The color of the iris is noted. Most light-skinned newborns have slate grey or dark blue eyes, whereas dark-skinned infants have brown eyes. Absence of color is characteristic of albinism. Although it is quite difficult to perform a funduscopic examination of the retina, a red reflex should be elicited. Absence of the red reflex may indicate the presence of retinal heamorrhages or congenital cataracts.

Ears

The ears are examined for position, structure, and auditory function. The pinna is often flattened, An otoscopic examination is ordinarily not performed because the canals are filled with vermix caseosa and amnioti fluid. making visualization of the drum difficult. Auditory sbility can be assessed by making a sharp, loud noise close to the infant's head. Normally the infant will respond with a startle reflex or twitching of the eyelids. Absence of any behavioral response to a sudden noise may indicate congenital deafness and should always be reported.

Nose

The nose is usually flattened after birth, and bruises are not uncommon. Patency of the nasal canals can be assessed by holding the hand over the infant's mouth and one canal and noting the passage of air through the unobstructed opening. If nasal patency is questionable, it should he reported because newborns are obligatory nose breathers.

Thin white mucus is very common in the newborn, but a think, bloody nasal discharge without sneezing is very common in the newborn. Flaring of the nares is always noted because it is a serious sign of air hunger from respiratory distress.

Mouth and throat

The doctor inspects the mouth to identify existing structures. The palate is normally high-arched and somewhat narrow; a common finding is Epstein's pearls- small, white, epithelial cysts along both sides of the midline of the hard palate. They are insignificant and disappear in several weeks.

The frenulum of the upper lip is a band of think, pink tissue that lies under the inner surface of the upper lip and extends to the maxillary alveolar ridge. It usually disappears as the maxilla grows. It is particularly evident when the infant yawns or smiles. The sucking reflex is elicited by placing a nipple or tongue blade in the infant's mouth. The infant should exhibit a strong, vigorous suck. The rooting reflex is obtained by stroking the cheek and noting the infant's response of turning toward the stimulated side and sucking.

It is difficult to examine the back of the throat. If the doctor attempts to depress the tongue, the infant objects with strong reflex protrusion of the tongue. Therefore, it is best to visualize the Uvula while the infant is crying and the chin is depressed. However, the Uvula may be retracted upward and backward during crying. Tonsillar tissue is generally not seen in the newborn.

Neck

The newborn's neck is short and covered with folds of tissue. Adequate assessment of the neck requires allowing the head to fall gently backward in hyper-extension while the back is supported in a slightly raised position. The doctor observes for range of motion, shape, and any abnormal masses.

Got Learning Skills?

Speed Reading: Got Learning Skills?

How smart am I, when I just typed illiteracy with one L instead of two? Do I

qualify as a certified illiterate? Nyet - because I have the spelling knowledge and corrected the mistake when I saw it.

Tell me if you know that 10% of the U.S. population of 306 million (30+ million folks) cannot read and comprehend a simple written English sentence? Wait – how about the fact 27 million folks cannot fill out a readable job application without help?

Google: National Institute of Literacy, March 3, 2008.

Knowledge

Would you volunteer to spend 30 seconds daily for 21 days, to permanently create new learning habits to double your reading speed? What if these baby-easy exercises also add up to 50% to your long-term memory? Deal? Read on.

Answers

We all have six muscles in each eye; four (4) use our Rectus muscles, and two (2) contract our Oblique muscles used for acute (sharp) vision. We hardly exercise four of our six eye muscles because we rely on using our convergent (binocular) vision for reading, tv, and computer use. We largely ignore our peripheral (side) vision.

How

If you can look upward toward the ceiling, downward to the floor, and to your

extreme left and right sides, you can exercise your six (extraocular mucles) in each eye. How long? Just 30 seconds is all it takes to exercise all twelve of them.

Why bother?

Ever notice any Floaters (spots) flying around your path of vision? These voluntary

eye movements can help eliminate Floater Spots. There are credentialed U.S. ophthalmologists who recommend extraocular eye muscle exercise to avoid Cataracts, Macular Degeneration, and the onset of Detached Retina.

We do it to avoid Dry Eye and mental fatigue after using our computer up to six hours daily. Remember, only after you lose part or all your vision, do we appreciation our magnificent eyesight.

Step One: Come on, it is baby easy. Sit down, look straight ahead, and do not move

your head. Now focus your eyes as extreme left and then extreme right as they go.

Keep count each eye movement left-and-right is one-point. Do 20 lateral eye movements.

Step Two: Head still, eyes straight ahead, and voluntarily move your eyes to your

extreme UPPER left and Upper right. See as high as possible, and feel as if you

are stretching your eye muscles. Each left-and-right eye movement equals one-point.

Do 20 upper eye muscles contractions.

Step Three: Head still, and eyes focused forward. Voluntarily move your eyes DOWNWARD, and to your extreme left, and then to your extreme right (downward) side.

Each left-and-right voluntary eye movement equals one point. Do 20 downward

eye muscle contractions. It only requires up to 30 seconds to complete.

Put this in prospective – is your healthy eyesight worth half-a-minute daily?

Remember this old cliché – use-it-or-lose-it. Yes, it applies to your extraocular vision too. Do a Mind Exercise using your eye movements and you be the judge.

Inquiring Mind Want to Know

Two of our students (executives) at a Fortune Five Hundred company asked about

hearing the words they read in their mind. Like in your mind’s eye, this is in your

mind’s ear. The average U.S. college graduate reads Basic English at about 210 words per minute.

Now here is the funny thing – the average speed of speech (conversation and lecture)

is about 210 words per minute. Wait – the average reading speed and speaking rate

are identical?

Sure, because college graduates can read no faster than they can speak. How come?

We must hear the words we read in our heads (auditory association cortex) to derive

comprehension from them.

When there is an absence of mental recitation (hearing the internal dialogue) there is no understanding of the sentences. It is called Subvocalization.

Speeding Up The Process

If you change your eye movements, you can see and comprehend multiple words

simultaneously. That means you can read and understand a minimum of three (3)

words at a time instead of the normal rate of just one word at a time.

The Secrets

First, you need a tool to trigger your peripheral (side) vision to take in three words

at a time instead of just one. If you can learn to underline while you read, you activate a powerful human instinct. Your eyes must follow a moving object and automatically speed up.

Grab a pen to use as a Pacer for your eyes to follow. You will automatically (after practice) first double, and then triple your normal text reading speed.

Second, widen you eye focus (Go Wide, Go Lizard) to fix on two and three words

with each eye fixation. It takes practice, and is called Chunking. You goal is to

mentally divide each sentence you read into groups (piles) of three-words each.

Third, physically move your head as you read (underlining the sentences) left to right. Why? When you head is fixed (still), you eyes lose sharp focus. When you

intentionally move your 3 pound coconut left to right as you read, you maintain the words of each sentence within the fovea (central vision) and maintain 100% sharp eye focus.

Google: Vestibulo-Ocular Reflex. After practice it become a habit, on autopilot.

Endwords

Would it benefit you to own the skill of reading and remembering three (3)

books, reports and articles in the time your competitors can hardly finish even one?

Will this permanent skill help students and executives in their career advancement?

Ask us how.

See ya,

True or false questions...if its false, write the correct answerr. thank youuu!?
t or f- white blood cells are responsible for the clotting of blood.
t or f- the exchange of gases takes place in the air sacs (alveoli) of the lungs.
t or f- the basic function of respiration is to supply the body's need for energy.
t or f- nitrogenous wastes are gotten rid of through the organs called the kidneys.

t or f- the cochlea in the inner ear transform sound impressions into nerve impulses.
t or f- the adrenals and pituitary are examples of endocrine glands.
t or f- glands secrete chemical messengers called hormones

Here are the ones I know off the top of my head:

t or f- white blood cells are responsible for the clotting of blood.
False - thrombocytes.

t or f- the exchange of gases takes place in the air sacs (alveoli) of the lungs.
True

t or f- the basic function of respiration is to supply the body's need for energy.
True.

t or f- communication in the nervous system is carried out by neutrons.
False - neurotransmitters

t or f- the messages involved in automatic reflexes are coordinated by reflex centers in the brain.
False... the signal from reflexes never reaches the brain, it loops in the spine.

t or f- the adrenals and pituitary are examples of endocrine glands.
True, though to be specific, the adrenal glands are also exocrine glands.

t or f- glands secrete chemical messengers called hormones
This one's weird. Yes, some glands secrete hormones. Some glands don't (salivary glands, for instance) Ask for clarification on this question. And arguably, the hormone is a chemical message, not a messenger.

Cell Transplants for Macular Degeneration
A stem-cell startup aims to test neural stem cells for treating two leading causes of blindness. Rats genetically engineered to lose their sight can be protected from blindness by injections of human neural stem cells, according to research presented at the International Society for Stem Cell Research conference in San Francisco last week. StemCells , a startup in Palo Alto, CA, plans to use the ...
