Effect Of Myopia On Measuring Peripapillary Retinal Nerve Fiber Layer Thickness ABSTRACT Settings: Faculty of Medicine, Alexandria University, Egypt. Purpose: To assess the influence of axial length (AL) and refractive status of the eye on retinal nerve fiber layer (RNFL) thickness in myopic eyes measured by spectral domain optical coherence tomography (OCT). Methods: This study included 60 eyes of 60 healthy myopic individuals. Patients with a history of glaucoma or any other concurrent ocular

Electromyography and Nerve Conduction Studies An electromyogram (EMG) gauges the electrical activity of muscles at rest and during contraction. Nerve conduction studies (NCS) measure how well and how fast the nerves can send electrical signals. The nervous system is a complex, sophisticated system that regulates and coordinates body activities. It is made up of two major divisions: the central nervous system (the brain and spinal cord) and the peripheral nervous system (all other neural elements)

gradually. Nerve damage is interfering with the functioning of the peripheral nervous system (PNS). Damaged nerves can occur in the brain and spinal cord and affect how the peripheral nervous system communicates with the rest of the body, it sends incorrect signals which can be a risk factor for falls. He is not a diabetic which is one of many causes of neuropathy. Neuropathy can affect the nerves that provide feeling or cause movement, if both are affected it is called sensorimotor. The nerve fibers

536-538 & 542-543). INTRODUCTION Give a brief description in your own words of the objectives and aims of this practical. The aim of this practical was to discover the effects that numerous hormones and drugs have on the sample ileum’s nerves and relate this to the human autonomic nervous system. The objectives include observing the change in contractions during different levels of stimulation and inhibition, such as that from different

cell, to produce physical and chemical reactions. Neurons or nerve cells are excitable cells. They receive, process and transmit information as electrical/chemical signals. Those signals are called Action Potentials and they have specific properties and characteristics. We wanted to gain practical experience and study some of the nerve impulse and muscle contraction behavior by stimulating an isolated sciatic nerve and a sciatic nerve/muscle from a cane toad; in a controlled environment, with the

system is a network of neurons (nerve cells that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system. The neuron has two important structures called the dendrite and axon, also called nerve fibers. The dendrites are like tentacles that sprout

Lumbosacral Neuritis What is lumbosacral neuritis? These are nerves that are in the lower spine, specifically In the lumbar region. The nerves become inflamed and irritated, from picking up heavy objects and also twisting. The (5) vertebra affected are L1 throughL5 and the large bone at the base of the spine is the sacrum which connects the spinal column to the pelvis. There are a number of things that can cause lumbosacral neuritis as follows, compressed spinal column, infection such as hepatitis

is to optimize all of the different parameters that are inputted into the system so that the the presence of the beads will be minimized, so that the integrity of the scaffolds are maintained. Specific Aims 1: Assessing scaffold sufficiency for nerve

typically slow growing tumor that develops on the eighth cranial nerve. The incidence of developing this neuroma is 1 in 100,000 people per year according to Science Direct (Ho & Kveton, 2012). It is estimated that 2,500 new tumors per year are diagnosed in the United States alone. Information on how acoustic neuromas actually evolve, treatment options, advantages and disadvantages of treatment options, and preservation of the facial nerve during surgery will all be discussed in this paper.

Amyotrophic lateral sclerosis is commonly referred to as ALS. This disease is also known to many as Lou Gehrig’s disease. ALS is a disease characterized by the slow death of certain nerve cells in the brain and spine. As described by research done through the Mayo Clinic, nerve cells called motor neurons control the muscles that allow you to move muscles of your body. ALS effects these particular neurons and produce serious neurological effects that can start as muscle weakness that eventually leads
