The Signal

A distal transhumeral amputation typically occurs above the elbow. Cheesborough et al. suggest preserving the humerus bone segment at an approximate length of 6 to 8 cm. In addition to the length they recommend fixating the humerus at a 70 degree angle with a metal plate to give the arm rotational and leverage control when using a prosthetic arm (Cheesborough et al.,2015). In addition the shape and length of the residual humerus bone allows for increased suspension of a prosthetic arm (Tintle…

Motor function and motor control begin in the motor cortex of the brain. The primary motor cortex is associated with generation of a motor program. Premotor areas are involved in complicated motor functions, such as required changes in output forces or velocities, or motor response to visual or auditory input. Also, the basal ganglia and thalamus are important coordinating centers for goal­directed motor programs and patterns. The cerebellum allows for unimpeded movements of those motor programs…

Symbolism is often used by authors to represent important ideas or qualities in literature. Objects, situations and even people, are used to represent those specific concepts that the author is trying to communicate to the reader. In the novel, Lord of the flies, William Golding applies symbolism throughout the book to represent the theme of civilization and savagery that is explored in the novel. One of the very first symbolic objects was the conch shell discovered on the beach by Ralph and…

upper motor neurons send messages from the brain to the spinal cord and the lower motor neurons send the signals from the spinal cord to the muscles throughout the body. With ALS patients the spinal cord is not receiving the signals from the brain, so the voluntary muscles are not receiving any signals. As figure 3 illustrates a normal motor neuron and ALS motor neuron. As time goes by the signals that goes to muscles grows weak, and you start to lose control of body movements. It starts off…

According to the WHO and MHO statistical yearbook, 42 percent of the death in 2010 are caused by cardiomyopathy diseases in Saudi Arabia. The rates of death in 2010 is 375 out of 100,000. According to the new statistical yearbook for 1431H, the death rates declined from 17.99 percent to 16.39 percent in the year 2008,2009 and 2010. Ischemic cardiomyopathy is one type of cardiomyopathy. According to Cleveland Clinic,” In Ischemic CM, the heart's ability to pump blood is decreased because the…

performance gradients is essential for achieving the shortest TR and TE possible to maintain high image contrast and signal to noise ratio with relative short scan times (Currie et al., 2013). A 6 element phased array body coil, which placed onto the patient, in conjunction with the spinal matrix coil that has a 12 element design built into the scanner table, are used to provide a superb signal-to-noise ratio (SNR) and achievable spatial resolution (Currie et al., 2013). This phased-array coils…

router might have a range of45m indoors and 90m outdoors. 6. The most common wireless encryption standard, WEP has been showed to be breakable even after correctly configured. 7. The Wi-Fi modem use dangerous electromagnetic radiation to send the signals to your computer through walls. This electromagnetic radiation can harm you and cause many of the…

disturbances (for example, temperature, pain, itching, easily. How does the signal go from brain to skin? Various tactile receptors are attached to many types of nerves. Most receptors use fiber A beta to transmit their signals - they very quickly transmit information. In the brain we receive all types of impulses/information coming from different parts of the body being processed and integrated in the sensory cortex. Signals can be classified by the nature of the receptors (pain,…

Imagine being able to relax and live a pain-free life. When you suffer from chronic pan, it seems like nothing you do helps. You cannot focus on anything that you enjoy because you are constantly distracted by pain. If you suffer from chronic pain, you may wonder: “Why won't my pain go away?” “Do I have to take pain killers to treat my pain?” “Will I ever be able to enjoy life again?” Chronic pain is thought to affect 100 million Americans. It can be caused by many different diseases or…
