  • Myasthenia Gravis

    803 Words  | 4 Pages

    muscle weakness. Normally when impulses travel down the nerve, the nerve endings release a neurotransmitter substance called acetylcholine. Acetylcholine travels from the neuromuscular junction and binds to acetylcholine receptors which are activated and generate a muscle contraction. In myasthenia gravis, antibodies block, alter, or destroy the receptors for acetylcholine at the neuromuscular junction, which prevents the muscle contraction

    The population of college students in the town of shillong grows drastically with students coming from all corners of North Eastern States and other states as well. It is presumed that a shift from familiar circumstances to new surroundings will generate some kind of feelings of loneliness on individuals.

  • Muscular Dystrophy Case Study

    981 Words  | 4 Pages

    ntroduction Muscular dystrophy (MD) is a group of inherited diseases characterized by progressive weakness and generation of the skeletal muscles that control movement. The patient has to undergo “clinical examination and laboratory procedures, including electromyography, muscle biopsy, DNA analysis and selected enzymes levels assayed from blood samples” (Campbell, Palisano 2006). The most common form of muscular dystrophy occurring in children is Duchenne Muscular Dystrophy amongst other prevalent

  • Parasympathetic Ganglion Research Paper

    631 Words  | 3 Pages

    When the both sympathetic and parasympathetic ganglion direct to the same organ or gland the total function of the gland is carried by the input signals given by chain ganglia and the terminal ganglia. E.g. the sympathetic ganglion can increase the heart rate and the parasympathetic ganglion can decrease the heart rate. Terminal ganglia in the sympathetic nervous system receive impulses from the head, neck, thoracic and lumber regions. Terminal ganglia of the parasympathetic system receive impulses

  • Sliding Filament Theory Research Paper

    1013 Words  | 5 Pages

    Unit one The sliding filament theory: Before this unit I knew nothing about the sliding filament theory. After learning about the sliding filament theory, I discovered that, it is the contraction of a muscle. It slides the thin actin filament over the thick myosin filaments causing the muscle to shorten and create movement. When I researched more about the sliding filament theory I learned that each muscle fibre is made up by myofibrils, that consist of smaller structures called actin and myosin

  • Egg In Vinegar Lab Report

    738 Words  | 3 Pages

    CONCLUSION When you put an egg in vinegar, we see that the shell dissolves, but do you ever wonder why? An egg is made mostly out of calcium carbonate which reacts with an ingredient in vinegar, acetic acid. Acetic acid is about 4% of the vinegar and what breaks apart the solid calcium carbonate crystals. The bubbles we see, from the egg, is the carbonate that make carbon dioxide and the other calcium ions float free. This is the equation: CaCO3 (s) + 2 HC2H3O2 (aq) → Ca(C2H3O2)2 (aq) + H2O

  • Eugenol Case Studies

    1927 Words  | 8 Pages

    Eugenol at the concentrations of 0.2 -20 µm is suggested to be able to produce a dose dependent and reversible vasodilator response that are partially dependent on the endothelium (24). EUG has also found to have a preventive effect on dopamine depression and lipid peroxidation, which can protect depression induced by 6-hydroxyl dopamine (OHDA). Eugenol has prevented depression by decreasing lipid peroxidation and stimulating reduced glutathione (GSH) may lead to a protecting effect (25)

  • Function Of The Muscular System Essay

    442 Words  | 2 Pages

    P4 describe the function of the muscular system and the different fibre types Function of the muscular system The function of the muscular system is for the movement of the body. In the body there are averagely seven hundred muscles that make up halve a person’s body weight. There are three types of movement in the body and these are agonist, antagonist, and fixator. Muscles generally speaking work in pairs if we are pushing or pulling. For example a bicep curl, the bicep is the agonist causing

  • Myasthenia Gravis Research Paper

    1075 Words  | 5 Pages

    The infant may develop temporary muscle weakness and associated findings (i.e., transient neonatal myasthenia gravis). The passage of anti-acetylcholine receptor antibodies through the placenta to the unborn child during pregnancy may cause this condition to the infant. Some of the myasthenia gravis is inherited as an autosomal recessive, or more rarely, an autosomal dominant condition is described

  • Muscle Movement Essay

    414 Words  | 2 Pages

    The first step in the journey of muscle movement, is the motor neuron. The motor neuron provides Acetylcholine (ACh) which is crucial in muscle movement. Acetylcholine (ACh) is released from the synaptic terminals of the motor neuron. The ACh then travels across the synaptic cleft by way of diffusion. From the synaptic cleft, the ACh binds to the receptors located on the muscle fiber’s plasma membrane. After the ACh has found its way to the receptors and is bound to them, the muscle fibers become

  • Racism: Speech: A Speech On Racial Discrimination

    A pleasant morning to all of you. Thank you for being here listening to me. Today, I am going to talk about racial discrimination. Can you imagine that you are being discriminated because of who you are? For instance, imagine that you still cannot be promoted in your jobs even you are brilliant at it, or you are being mocked and ignored at school because of the color of your skins, religions or disabilities. You will feel unjust, grief and indignant, but there is no way for you to revolt. What’s

  • Medical Malpractice Examples

    Examples of Medical Malpractice Cases of medical malpractices have raised their ugly head quite often in last few years. We are all aware of the common malpractice cases. Birth injuries, pregnancy issues, mental health, paralysis due to wrong medications are few cases that have occurred repeatedly over a long period of time. However, malpractice cases have broken these barriers and caused harm to patients suffering from other commonly unknown diseases or disorders. We thought of listing some lesser

  • Four Physiologic Systems

    1711 Words  | 7 Pages

    How Four Physiologic Systems Work Together Neuromuscular System: The neuromuscular system is where the body starts when it begins to make a movement. It does this by the nervous system to the motor neurons. This signal that is sent is in the form of an electrical impulse. Once it gets to the motor neuron, it is intercepted via the dendrites. Afterwards the signal is sent to the axon hilock where is it determined by the neuron if it will be sent down the axon. It does this by utilizing IPSP’s and

  • Essay On Mechanomyography

    2198 Words  | 9 Pages

    CHAPTER 1 INTRODUCTION 1.1 Overview MMG (mechanomyography) is a technique for interpreting mechanical activity based on muscle contraction. The prediction of muscular tissue condition can be found using MMG, a technique that muscular mechanical waves produced during a fiber’s contraction and stretching that are sensed over skin surface [22]. The purpose of this research is to explore various methods of muscle activity through MMG signal to recognize multiple hand gesture. The evaluation of muscle
