Myelin Sheath In a neuron‚ the myelin sheath consists of fat-containing cells that insulate the axon from electrical activity. This can be compared such as the insulation of a house. The main purpose of the insulation is to increase the rate of transmission of signals in the neuron. There is a small gap between each myelin sheath cell along the axon. Since fat inhibits the proper agitation of electricity‚ the signals jump from one gap to another. The destruction or loss of the myelin sheath in

ELECTRIC MOTOR CONTROLS Once the proper motor is selected‚ understanding the many various control devices available and their uses and limitations becomes an important part related to reliable operation and protection of the motor and the personnel using the motor. Motor Control Topics There are four major motor control topics or categories to consider. Each of these has several subcategories and sometimes the subcategories overlap to some extent. Certain pieces of motor control equipment can accomplish

EPHE 380 – Motor Control Final Exam Ian Haig V00711512 Scenario: Walking down a 45 degree slope with a surfboard under my left arm and a large mountaineering backpack on my back. I was walking down the trail to Sombrio Beach which is about a 1.5k hike down a steep trail to the ocean. I had a surfboard under my right arm‚ an axe in my left hand‚ and a large 40 litre hiking backpack fully loaded with supplies on my back. About half way down there is a left turn in the trail which has a declining

Composition and Formation of Myelin Sheath Molecular Neurobiology Myelin may be made by different cell types‚ varies in chemical composition and configuration‚ but performs the same insulating function. Myelin is about 40% water; the dry mass of myelin is about 70 - 85% lipids and about 15 - 30% proteins. Some of the proteins that make up myelin are myelin basic protein (MBP)‚ myelin oligodendrocyte glycoprotein (MOG)‚ and proteolipid protein (PLP). The primary lipid of myelin is a glycolipid called

evidence that motor control exercise may be of benefit in the treatment of chronic low back pain patient populations. Motor control exercise is based on the idea that low back injuries cause inhibition of core stabilizing muscles‚ which will then atrophy over time (Hodges & Richardson‚ 1996; Richardson‚ Hodges‚ & Hides‚ 2007). Costa et al. (2009) found evidence supporting the that idea motor control exercise improves function and patient impression compared to a control group. The control group received

Mexico Tech Spring 2011 Lab 5 – Part 2 Final Project: Motor Speed Control Introduction and Objectives In this lab you will control the speed of a motor. Figure 1 shows the hardware setup‚ which is the same as for Week 1 of Lab 4. You will use the potentiometer on your evaluation board to set the desired speed of the motor‚ and you will control the speed through the PWM output of the HCS12. You will measure the speed of the motor using an input capture pin‚ and display the desired and actual

Physical Development The two main areas of physical development are gross & fine motor skills. Gross motor skills use the larger muscles in the body like arms & legs. Rolling over‚ crawling‚ walking‚ running and jumping are all gross motor skills. Fine motor skills use the smaller muscles in the body‚ like fingers & toes. Writing‚ painting‚ pointing‚ grasping and reaching are examples of fine motor skills. Fine motor skills alsto eye coordination. Activities to promote Physical Development
