all based on our primary five senses; sight hearing‚ touch‚ smell‚ and taste. Sensation is the pickup of information by our sensory receptors. For example‚ in vision sensation occurs when rays of light are collected by your eyes and focused on the retina. Also‚ sensation can occur due to a mental condition or from an internal body change such as becoming cold or having pain inside the body. Sensation could also be interpreted as a state of mind. Feeling excited or nervousness can all be considered

How The Skin is Involved with the Nervous System The skin is the outside covering of the body tissue‚ which protects inner cells and organs from the outside environment. The skin is the largest organ of the body and its cells are continuously replaced as they are lost to normal wear and tear. The skin has between 12 to 20 square feet in area and accounts for 12% of body weight. It is composed of 3 layers the epidermis‚ the dermis‚ and the sub cutis. The thickness of

Money is closely linked to our lives‚ so the financial institutions become an inevitable and important part of our lives and people are always focusing on the situation of financial institutions. So the banking industry is the most suitable topic to study. Then‚ we decided to use scenario model to analyze the industry (Showed by diagrams 1). [pic] Diagram 1 After analyzing the situation of the industry‚ we choose ten years because it is the most proper time for our scenarios. The

Case Report Clinical Assessment of a Patient With Compound Myopic Astigmatism and Convergence Insufficiency Abstract Myopic astigmatism is a specific type of astigmatism wherein the light focuses before it reaches the retina. This condition is classified as a combination of astigmatism and myopia‚ or nearsightedness. If both principal meridians are nearsighted‚ but one is more pronounced than the other‚ it is considered to be a compound myopic astigmatism. Convergence Insufficiency on

conjunctiva‚ which runs to the edge of the cornea the clear‚ curved layer in front of the iris and pupil. Light enters the eye through the cornea‚ the cornea serves as a protective covering for the front of the eye and also helps focus light on the retina at the back of the eye. After passing through the cornea‚ light travels through the pupil. The iris controls the amount of light that enters the eye. The pupil dilates and constricts as the amount of light in the immediate surroundings changes. The

Reading the Visual – Dr Daniel Chandler MC10220 Matthew Ruckwood 03/05/2005 The Perception of Motion Pictures “Why‚ when we look at a succession of still images on the film screen‚ are we able to see a continuous moving image?” During the late 1970s and early 1980s a small group of film scholars radically broke away from the time-honoured explanation of how the human eye (and mind) perceived the apparent motion in cinema. They abandoned the notions of ‘persistence of vision’ and the

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 of the pupil‚ regulation and suppression of

This was actually because of nuclear particles bombarding their retinas.

There is 1% chance in 10 years that a space shuttle can be destroyed by space junk. These junks
