Optic nerve

cranial nerve function is an important part of a neurological assessment (Department of Health Sciences, 2014). The brain has twelve main pairs of nerves, called cranial nerves. During a complete neurological assessment, most of the cranial nerves are evaluated to help determine the proper functioning of the brain (Neurological Examination, 2014). Each cranial nerve is paired and is present in each side of the brain. Cranial nerve I (Olfactory) is the sensory nerve of smell. Cranial nerve II…

facial pain. TN is defined by the International Headache Society (IHS) as “unilateral disorder characterized by brief electric shock-like pains, abrupt in onset and termination, and limited to the distribution of one or more divisions of the trigeminal nerve (Oberman, 2010). It is also known as “Tic Doloureux”. The exact cause of TN is still unclear, but the pain is triggered by several factors, such as eating, washing, shaving, cold, warmth, and draught (Van Kleef et al., 2009). According to…

Light synthesis principles The basic idea of light waveform synthesis can be described as follows: First, the spectrum of a light waveform is decomposed into its constituent spectral components by a disperser, then, adequate modulators acting on each of this spectral components individually modifies the relative phase (or delay), the amplitude and polarization of these components before they are coherently superimposed again by a combiner to create a desired tailored waveform (Figure 2a)41.…

is only natural that the great thinkers of antiquity were curious about the nature of vision, and inseparably, that of light itself. In the manner characteristic of ancient science, many common ideas about optics were “hit or miss”, so to speak. Certain Greek thinkers had hypotheses about optics which are more or less in line with modern principles, but many held firmly to ideas which are at odds with the current understanding of reality. I discuss extramission theory (a hallmark of Greek…

Introduction A lens is an object that forms images by refracting light. The images formed can be magnified, real and virtual depending on what lens used and the set-up of the lens system. There are two types of lenses, converging and diverging lenses. Converging lenses cause parallel light rays to converge to a point. Diverging lenses cause parallel light rays to diverge. Typically converging lens are thicker in the middle and diverging lenses are thinner in the middle. Lenses are used for many…

I. Introduction A. On an adventure to Milwaukee any tourist would go to the Milwaukee County Zoo. The first stop is always the penguin habitat. B. Have you ever paid attention to what species it is or where they came from? C. When we see penguins it is always in the zoo or part of an animation production. Here are 3 ways to analyze penguins from what is shown on the big screen to the natural habitat. II. When I think of penguins I think of penguins of Madagascar or the Pittsburg penguins. III.…

medial nerve, which is very common in those who use a keyboard and a mouse. When typing, finger should be in line with the forearms, not resting on the table. Use a gel keyboard pad, or even something like a towel. A way that we can prevent it from getting any worse is to use a keyboard pad, making sure that the desk is not too high for you, and not causing you to have your wrists completely rest flat on the desk in a prolonged extended position which would cause compression to the median nerve.…

For two months, as I followed every conceivable lead, Caulder grew nastier, fuming constantly about my incompetence. “What the fuck have you been doing with your time?” he bellowed. “Do you have any idea the flack the department will take, that I will take, if it comes out we killed a guitar player while trying to dispatch an ambassador’s daughter? I’m not letting you jeopardize my reputation—or my retirement.” “It’s not my fault. You taught her every trick she knows.” “She switched sides, Mark.…

Critical Appraisal Assignment Effect of Splinting and Exercise on Intraneural Edema of the Median Nerve in Carpal Tunnel Syndrome – An MRI Study to Reveal Therapeutic Mechanisms Student ID: 400042610 Course: PT611 Instructor: Professor Graham Date: Monday October 5, 2015 PICO QUESTION The study question developed using the PICO method to aid in the article search was: “In adults with carpal tunnel syndrome (CTS) do gliding exercises (GE) reduce pain and symptomatology in patients…

Carpal tunnel syndrome (CTS) is a hand injury which occurs at wrist joint and causes several problems at this joint, such as finger numbness, pain and muscle weakness. It happens as a result of compression of the median nerve which innervated thumb, index and middle finger (ASSH, 1990). This compression is caused by pattern of hand use, fracture at wrist joint and other medical conditions, for instance diabetes, obesity and rheumatoid arthritis (NHS, 2014). There are two ways to treat carpal…
