  • Amyotrophic Lateral Sclerosis

    Amyotrophic Lateral Sclerosis (The ALS Association, 2015). ALS is more commonly referred to as Lou Gehrig’s disease after Lou Gehrig, a great American baseball player whose career unfortunately ended abruptly due to this incurable degenerative disease. ALS is the deterioration of motor neurons in the brain and spinal cord that leads to muscle weakness. This significant decrease in muscle strength eventually becomes paralysis, and the majority of those with this awful disease die from respiratory failure. This is the most common neuromuscular disease and affects 12,000 people annually and about 4 out of every 100,000 people (National Institute of Neurological,…

  • Biceps Muscles Lab Report

    Figure 1. An EMG Tracing of Triceps and Biceps Muscles Co-activation. EMG signal produces an electrical activity of the muscle fibers active at a moment time. The electrical activity is measured in millivolts per milliseconds. The top channel shows the bicep EMG, while the bottom EMG correlates to the triceps contraction traces. Shown on the top graph, there are two periods of bicep activation, each last approximately 1.5ms. When the biceps are activated, it produces increasing amplitude peaks,…

  • HCSMA Case Studies

    no linkage to the sex chromosomes (Sack GH Jr, Cork LC, Morris JM, Griffin JW, & Price DL, 1984). Physiological Processes Hereditary canine spinal muscular atrophy is a condition that is inherited that affects the nervous system of the diseased canine. Studies have shown that the weakness of the skeletal muscles is caused by the atrophy of these muscle fibre in a proximal to distal gradient, type I muscle fibre is linked to the early neurogenic degeneration in the homozygous individuals…

  • Maximum Contraction Lab Report

    Introduction: Temperature can affect the rate at which an action potential is generated to excite an action potential within a given skeletal muscle. Maximum contraction is the ability of the muscle to recruit and produce its greatest force during a contraction, and we can observe these effects by using a grip force transducer, which records the functional grip force of the hand. Therefore, the purpose of this lab was to discern how varying temperatures affect maximum contraction. I…

  • Motor Neurone Disease Theory

    The process that is used by nurses and clinicians to consider a patient situation, collect data, process this data, make goals and implement interventions, evaluate outcomes and then finally, reflect on the learning outcomes from this process, is known as clinical reasoning (Hoffman, 2007). Clinical reasoning cycle is the tool that is used for the process of clinical reasoning. This paper will discuss management of Motor neurone disease using the clinical reasoning cycle as a framework. However,…

  • Beast Meat Quality In Poultry

    Introduction: The importance of this research paper is to clarify, discuss and understand the issues that impacts beast meat quality in poultry. The three main issues the poultry industry has been faced with is white striping of breast muscle, woody breast, and deep pectoral myopathy. These issues is not a medical or health issue for humans’ consumptions but, a quality issue of consumption. The white strip of breast muscle is strips parallel to the muscle fiber. It is mostly found in breast…

  • Skeletal Muscle System

    The skeletal muscle system is made of many skeletal muscle fibers which have at least one neuromuscular junction. A neuromuscular junction is the area of the skeletal muscle fiber that is innervated by a motor neuron (motor nerve). It plays a key role in body movement and breathing along with our nervous system. The synaptic knob, motor end plate, and the synaptic cleft are all key parts of the neuromuscular junction. The synaptic knob of an axon connects with a skeletal muscle fiber to form the…

  • Sciatic Nerve Experiment

    This study analyzed the differences and the relationships of the isolated sciatic nerve in regards to the compound action potential and the neuromuscular junction stimulations of the Rana pipens gastrocnemius. A total of five exercises were used to identify the effects on the stimulation of the sciatic nerve and the gastrocnemius. A dissection for both labs were performed to isolate the nerve and to isolate the gastrocnemius. Both experiments used LabChart to perform various stimulations on the…

  • Myasthenia Gravis Research Paper

    Myasthenia gravis What is myasthenia gravis? Myasthenia gravis is a medical condition characterized by autoantibodies against acetylcholine receptors at the neuromuscular junction, resulting in muscle weakness. Patients often have involvement of their ocular (eye) and bulbar muscles. The bulbar muscles are located in the head and are important for chewing and swallowing. Symptoms often include double vision, eyelid drooping, slurred speech, and dysphagia (trouble swallowing) due to muscle…

  • What Is Meant By Agonist In Muscle Pairs

    insertion”? What is meant by muscle origins is the location where the muscle attaches to the most stationary bones. While insertion is the the end location where the muscle is attached to the bone most moved. An example for the origin of the latissimus dorsi is the lumbar and lower half of the thoracic vertebrae as well as the iliac crest and lower sacrum. The insertion would be the the humerus. 38576259525 Essay QuestionsPicture 1 1. The junction between nervous and muscular system that sends…
