LIMITATION OF SIGHT AND HEARING INTRODUCTION Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Most of the limitation of sight can be overcome with the help of certain optical instruments such as magnifying glass‚ microscope‚ binoculars and others. The range of frequency of hearing in human 20 Hz to 20 000 Hz. It was different according to the age of a person. Hearing limitations can be overcome by using devices such as microphone‚ stethoscope‚ earphone

SENSE OF SIGHT…. The eyes are sensory organs. They keep the brain updated with information about is what happening around the body. Both contain millions of tiny sensors that send messages along nerves to the brain. Sensors in the eyes respond to light and‚ through the brain‚ let us see the world. Sensors in the skin respond to touch and allows us to feel. * * * * The seeing eye… Light enters the eye through the clear cornea. It then passes through the

technical article I read was called "Ultra sound warning: Procedure may harm unborn babies’ brains." This article explained the danger to unborn babies when ultrasounds are performed on the mother to be. Research has been conducted to test the danger of ultrasounds on unborn mice. The research has shown some of the dangerous sides of ultrasounds. The mice were injected while in the womb to track their brain development. There were 335 mice injected. The research showed that the pregnant

Medical sonography (ultrasonography/ultrasound) an ultrasound-based diagnostic imaging technique used to visualize muscles and internal organs‚ their size‚ structures and possible pathologies or lesions. (TheFreeDictionary.com‚ n.d.) Medical sonography was first applies to the humans body for medical purposes by Dr. George Ludwing at the Naval Medical Research Institute‚ Bethesda‚ Maryland in the late 1940s. (TheFreeDictionary.com‚ n.d.) For an ultrasound to work there are events that must happen:

Because of this‚ they are often used as ancillaries of each other. However‚ their significance cannot be deprecated as each of them has its preferred areas of applications. Sonography (or ultrasonography) is an imaging technique that makes use of ultrasound to construct images of subcutaneous body structures such as tendons‚ muscles‚ vessels and joints. An image obtained through sonography is called a sonogram. The professional who performs ultrasonography is called a sonographer. This paper has been

Ultrasonography‚ commonly called sonography‚ is a diagnostic medical procedure that uses high frequency sound waves (ultrasound) to produce dynamic visual images of organs‚ tissues‚ or blood flow inside the body. This type of procedure is often referred to as a sonogram or ultrasound scan. Sonography can be used to examine many parts of the body‚ such as the abdomen‚ breasts‚ female reproductive system‚ prostate‚ heart‚ and blood vessels. Sonography is increasingly being used in the detection and

Ultrasound Physical effects of ultrasound: 1- Thermal effects 2- Non-thermal effects 3- Effect of US in tissue repair First: thermal effect @ It is due to generation of heat within the tissue due to adsorption of US. @ Tissue with high amount of protein absorbs US more than other tissues. @ Generation of heat within the tissue will decrease pain‚ joint stiffness & increase blood flow. @ Thermal effect achieved if the temperature of the tissue is raised to 40°c - 45°c for at least

sonography also known as "ultrasound" was first attempted after WW2 using sonar equipment. But the electronics back then were too slow for the very short distances and high resolutions required for medical imaging. With the development of microchips‚ sonography has made huge advancements. Many individuals around the world have contributed to these incremental advances. The American Institute of Ultrasound in medicine was the first professional organization devoted to ultrasound. The AIUM began in 1951
