Neuromuscular disease

an autoimmune muscular junction disease that targets nerves and muscles (What is Myasthenia Gravis, 2010). Myasthenia gravis attacks voluntary muscles such as the facial muscles, limbs and other muscles, making these muscles weak and sometimes immovable. Someone who has myasthenia gravis that has attacked the face can have droopy eyes, blurred vision and might lack the ability to smile because of the weakening of muscles (Pressman 2014). Patients with the disease in other muscles might have a hard

available AChR at the postsynaptic membrane as well as a flattening of the postsynaptic folds. Therefore, even without the phenomenon of presynaptic rundown, MG can result in an inefficient neuromuscular transmission due to a reduction in the number of AChRs at the motor end plate. The inefficient neuromuscular transmission and presynaptic rundown phenomenon account for the fatigability seen in MG due to the progressive decrease in the amount of muscle fibers that are activated with each successive

I Abstract: The purpose of this research is to compares hospital at home and patient in hospital care for neuromuscular disease (NMD) patients with respiratory tract infections. The main outcome measures were need for hospitalization, treatment failure, time to recovery, death during the first 3months following exacerbation, and cost of patient care. The diagnoses of NMD were based on the standard clinical, DNA, and biopsy data. The diagnosis of a respiratory tract infection was based on the presence

During prolonged activity, muscles show a decline in ability to respond to stimulation with optimal levels of contractile activity; this is a phenomena denoted as muscle fatigue (MF) (1). The causes of MF are not yet understood, however there are many observations of associations between metabolic and biochemical factors with MF. In order for force to be generated by muscles, calcium ions which are released from the sarcoplasmic reticulum bind to troponin. The new troponin-Ca2+ complex cause’s tropomyosin

Assignment D Case Study Chapter 11 (6th) 1. D. Nerve impulses from motor neuromuscular junctions are unable to fully stimulate the affected muscle because the antibodies target the acetylcholine receptors at the neuromuscular junction. As a result, the muscles are not told to fire properly. 2. A. Increases the availability of acetylcholine at postsynaptic receptor sites. Edrophonium chloride blocks the breakdown of the acetylcholine and would make the muscles stronger. 3. C. Increase muscle excitation

My refuge as a child was the library. The walls and isles lined with books, the smell of pages, and the quietness was my tranquility. I spent my days at the library, reading and playing games and puzzles; timing and challenging myself to see if I could do them faster and better. I was easily lost in adventures, ideas, and minds of characters through endless hours of reading. It was this time spent at the library that ignited my curiosity to understand how things worked, and sparked my passion for

Part l - Rise and shine? 1) What components of the nervous system are involved in physical sensation? How does sensory impulse move throughout the body? Pertaining to the peripheral nervous system, it is found the sensory division of it. The neurons that form this division, also called afferent neuron, transmit electrical impulses from several receptors located throughout the body to the central nervous system in order to further analyze and process the stimuli. 2) What components of the nervous

Introduction 1.1 Hereditary spastic paraplegias Hereditary spastic paraplegias (HSPs) are a group of clinically and genetically heterogeneous neurodegenerative disorders that share the primary feature of progressive lower limb spasticity and weakness, with sparing of the upper extremities (Blackstone et al., 2010). Although few epidemiological studies have been carried out, the prevalence of HSPs has been estimated to range from ~3-9 per 100,000 and the age of onset can vary widely, from early childhood
