1. The Effect of Pilocarpine and Tropicamide on Human’s Pupil 2. Throughout the experiment‚ we have learned how to measure the pupil diameter using a pupillometer‚ how to measure the near point of accommodation using a accommodometer and how to demonstrate the pupillary light reflexes by shining the light on the pupil. Besides that‚ we have learned the effect of 1% tropicamide and 2% pilocarpine on the human’s pupil and how the drugs will affect the pupil diameter‚ near point of accommodation

affective was to test if someone has cystic fibrosis; which are the sweat test‚ genetic test and newborn screening. The most effective and simple diagnostic test for cystic fibrosis is the sweat test. With this test a little pitch of the drug pilocarpine is applied on the skin and then a small electrical shock will be put to the area‚ which helps the drug enter the skin. Once the drug has enters it starts to sweat in the area being treated. The sweat is then soaked u by filter paper and is then

Human Eye The eye is a wonderful and the most complex organ of the human body. It is strange to learn that such a small organ has so many parts. The human eye provides us with the ability to visualize the world around us. Light enters the eye through the cornea and excites special neurons on the retina. The brain receives this information and interprets it so that we are aware of what we are seeing. The parts of the eye contribute to its proper function. A. Parts of the Human Eye A1

The eye is a rather small part of the body that makes up seventy percent of the humans total sensory ability. That is why we chose to describe the eye. Each part of the eye works together as a whole. Within and outside of the eye there are many working parts functioning around the clock.. The cornea is a very important part of the eye‚ but you can hardly see it because it’s made of clear tissue. Like glass‚ the cornea gives your eye a window in which to view the world. The a cornea is a

The human eye is the organ which gives us the sense of light allowing us to learn more about the surrounding world than any of the other five senses. We use our eyes in almost everything we do whether reading‚working watching television ‚writing a letter driving a car and countless other activities The eye allows us to see and interpret the shapes‚ colors‚ and dimensions of objects in the world by processing the light they reflect of give off.

The Eye is the organ of sight. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight‚ or vision‚ is a rapidly occurring process that involves continuous interaction between the eye‚ the nervous system‚ and the brain. <br><br>When someone looks at an object‚ what he/she is really seeing is the light that the object reflects‚ or gives off. This reflected light passes through the lens and falls on to the retina of the eye. Here‚ the light induces nerve impulses

Chapter – 11 The Human Eye and the Colourful World Q 1. What is meant by power of accommodation of the eye? Ans. The ability of the eye lens to adjust its focal length‚ so as to clearly focus rays coming from distant as well a near objects on the retina‚ is called the power of accommodation of the eye. Q2. A person with a myopic eye cannot see objects beyond 1.2 m distinctly. What should be the type of the corrective

The human eye is an organ which reacts to light for several purposes. As a conscious sense organ‚ the eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors.[1] In common with the eyes of other mammals‚ the human eye’s non-image-forming photosensitive ganglion cells in the retina receive the light signals which affect adjustment of the size

INTRODUCTION The human eye is one of the most complex organisms in the human body – second only to the brain. It is the organ which gives us the sense of sight‚ allowing us to observe and learn more about the surrounding world than we do with any of the other four senses. We use our eyes in almost every activity we perform‚ whether reading‚ working‚ watching television‚ writing a letter‚ driving a car‚ and in countless other ways. Most people probably would agree that sight is the sense they value

Human visual hardware is a result of a billion years of evolution within the earths atmosphere where light is scattered by molecules of air‚ moisture‚ particular matter etc. However as we ascend into our atmosphere with decrease density‚ light distribution is changed resulting in our visual hardware receiving visual data in different format. Some Aspects to Consider: 1. Visual acuity is the degree to which the details and contours of objects are perceived. Visual acuity
