How We See
How We See samer kareem 3,103 Views • 2 years ago

The eyes A close up of a young person's eyes. The eyes are responsible for four-fifths of all the information our brain receives. Here you can find out a bit more about how they work, common problems that affect vision and the work Sightsavers does to treat and prevent avoidable blindness. You can also find out more about the people whose lives have been changed thanks to donations from people like you. How do eyes work? (click image to see enlarged version or click here for text alternative) Graphic of an eye with information about its different parts The images we see are made up of light reflected from the objects we look at. This light enters the eye through the cornea. Because this part of the eye is curved, it bends the light, creating an upside down image on the retina (this is eventually put the right way up by the brain). The retina is a complex part of the eye, but only the very back of it is light sensitive. This part of the retina has roughly the area of a 10p coin, and is packed with photosensitive cells called rods and cones. Cones are the cells responsible for daylight vision. There are three kinds – each responding to a different wavelength of light: red, green and blue. The cones allow us to see images in colour and detail. Rods are responsible for night vision. They are sensitive to light but not to colour. In darkness, the cones do not function at all. How do we see an image? The lens focuses the image. It can do this because it is adjustable – using muscles to change shape and help us focus on objects at different distances. The automatic focusing of the lens is a reflex response and is not controlled by the brain. Once the image is clearly focused on the sensitive part of the retina, energy in the light that makes up that image creates an electrical signal. Nerve impulses can then carry information about that image to the brain through the optic nerve.

Coarctation of the Aorta
Coarctation of the Aorta samer kareem 10,235 Views • 2 years ago

A narrowing of the major artery (the aorta) that carries blood to the body. This narrowing affects blood flow where the arteries branch out to carry blood along separate vessels to the upper and lower parts of the body. CoA can cause high blood pressure or heart damage.

Blood Flow Through the Heart
Blood Flow Through the Heart samer kareem 6,339 Views • 2 years ago

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

Down syndrome (trisomy 21)
Down syndrome (trisomy 21) samer kareem 6,562 Views • 2 years ago

The term trisomy is used to describe the presence of three chromosomes, rather than the usual matched pair of chromosomes. For example, if a baby is born with three #21 chromosomes, rather than the usual pair, then the baby would be said to have "trisomy 21." Trisomy 21 is also known as Down syndrome. Other examples of trisomy include syndromes like trisomy 18 and trisomy 13. Again, trisomy 18 or trisomy 13 simply means the child has three copies of the #18 chromosome (or of the #13 chromosome) present in each cell of the body, rather than the usual pair.

Ehlers-Danlos Syndrome
Ehlers-Danlos Syndrome samer kareem 12,756 Views • 2 years ago

Ehlers-Danlos syndrome is a group of disorders that affect the connective tissues that support the skin, bones, blood vessels, and many other organs and tissues. Defects in connective tissues cause the signs and symptoms of Ehlers-Danlos syndrome, which vary from mildly loose joints to life-threatening complications. Previously, there were more than 10 recognized types of Ehlers-Danlos syndrome, differentiated by Roman numerals. In 1997, researchers proposed a simpler classification that reduced the number of major types to six and gave them descriptive names: the classical type (formerly types I and II), the hypermobility type (formerly type III), the vascular type (formerly type IV), the kyphoscoliosis type (formerly type VIA), the arthrochalasia type (formerly types VIIA and VIIB), and the dermatosparaxis type (formerly type VIIC). This six-type classification, known as the Villefranche nomenclature, is still commonly used. The types are distinguished by their signs and symptoms, their underlying genetic causes, and their patterns of inheritance. Since 1997, several additional forms of the condition have been described. These additional forms appear to be rare, affecting a small number of families, and most have not been well characterized.

Adrenoleukodystrophy, or ALD, is a deadly genetic disease that affects 1 in 18 000 people. It most severely affects boys and men. This brain disorder destroys myelin, the protective sheath that surrounds the brain's neurons -- the nerve cells that allow us to think and to control our muscles.

Como Aumentar La Libido, Aumentar Niveles De Testosterona, Como Aumentar El Deseo Masculino ---- http://aumentar-testosterona.good-info.co/ --- ¿Se puede tener una erección con bajos niveles de testosterona? Mi libido está quedando atrás y estoy teniendo dificultades para conseguir una erección, así que estoy tratando de averiguar qué está pasando aquí. La disfunción eréctil rara vez es causada sólo por la deficiencia de testosterona. Por lo general es un grupo de cosas que funcionan en concierto juntos, que se alimentan entre sí, que conducen a la incapacidad del hombre para lograr una erección. La aterosclerosis (estrechamiento y endurecimiento de las arterias) es uno de los mayores impulsores de la disfunción eréctil, pero estas arterias dañadas no aparecen de la nada. Otras cosas tienen que estar sucediendo en el cuerpo para que ésta aterosclerosis pase, y como estamos a punto de ver, estas otras cosas contribuyen al problema también. Así que vamos a repasar esta lista… Nivel de azúcar alto – baja testosterona y disfunción eréctil La azúcar elevada en la sangre es un arma de doble filo, porque los hombres que sufren de esta condición son mucho más propensos a ser afectados por la disfunción eréctil y la testosterona baja. Una Investigación de John Hopkins encontró que las ratas diabéticas presentaron una respuesta eréctil 30% inferior, sus erecciones fueron como máximo 40% más pequeñas y las erecciones tomaron 70% más tiempo para lograrse en comparación con los controles que no eran diabéticos. Otros estudios han confirmado que los hombres con diabetes tipo 2 son dos veces más propensos a sufrir de disfunción eréctil, y la condición les golpeará una década antes, en comparación con los hombres sin tipo 2. Este vínculo es tan fuerte porque el azúcar en la sangre hace un daño directo a las arterias cuando se tiene demasiado de él, y las arterias en el pene suelen ser afectados en primer lugar, porque son muy pequeñas y estrechas. Por lo tanto, tiene todo el sentido que éstas pueden dañarse primero. El ejercicio que baja la testosterona haga click aqui http://aumentar-testosterona.good-info.co/

Treatment of sinusitis in children
Treatment of sinusitis in children samer kareem 3,556 Views • 2 years ago

Antibiotic therapy is the mainstay of medical treatment for pediatric rhinosinusitis.] Because of increasing prevalence of beta-lactam–resistant bacteria in the community, administer antibiotics only for suspected infection as based on a careful history and physical examination. Direct the therapeutic regimen against the prevalent pathogens in the community and carefully consider suspicion for highly resistant bacteria. Typically, uncomplicated cases of acute sinusitis are responsive to amoxicillin. Most patients respond to this initial regimen. For children allergic to penicillin, a second- or third-generation cephalosporin can be used (only if the allergic reaction is not a type 1 hypersensitivity reaction). In cases of serious allergic reaction, a macrolide or clindamycin can be used.
