A muscle is a group of cells called fibers‚ and are generally quite big. One muscle fiber has a large amount of myofibrils‚ which are muscle proteins in the shape of cylinders. These myofibrils contain two different types of filaments‚ which run along the axis of the fiber in hexagonal patterns. The two types of filaments are thick and thin filaments. Every thick filament is surrounded by six thin filaments. Both thick and thin filaments are attached to a structure called the Z-line. The Z-line runs

1. Describe the main muscle groups of the body and their function There are three main categories that the muscles in the human body fall into: • Skeletal Muscle Skeletal muscle is the foremost area of concern for a sports masseuse. The main functions of this muscle group is to move the body in a voluntary manner‚ for example‚ if you want to kick a ball you will voluntarily have to send a signal through your brain to inform the muscles in your legs to contract/flex/extend and execute the skill

Comparison of Muscle Proteins to Infer Evolutionary Relationships of Mammals‚ Fish and Birds Abstract This experiment used electrophoresis to examine the makeup of muscle proteins from two mammals (cow‚ Bos taurus; bear‚ Ursus americanus)‚ two aves (chicken‚ Gallus gallus; turkey‚ Meleagris gallopavo)‚ and two fish (King Salmon‚ Oncorhynchus tshawytscha; Albacore Tuna‚ Scombridae unclassified). The hypothesis was that as species have diverged evolutionarily‚ the makeup of their muscle proteins

Performing circulatory observations on an individual who has recently undergone a PCI is crucial for detecting any localised vascular complications such as bleeding‚ hematoma‚ swelling‚ ecchymosis and pseudo-aneurysms. When learning in the hand over that Mr. Bright had “cold” feet post-op‚ it became clear that a prompt assessment for the colour‚ warmth and sensation of Mr. Bright’s feet and lower limbs was necessary to ensure that he

States of Muscle Dystrophy and relation to Dystrophin Muscle dystrophy branches into many different kinds of muscle disease including myositis‚ multiple sclerosis and fibromyalgia. What makes it so important is that muscle dystrophy can be found in patients as young as infants and as old as adults. Also‚ some types of muscle dystrophy can be progressively disabling. Muscle diseases are present in infants and children because many of the diseases are hereditary. For example‚ Duchenne muscular dystrophy

HOW MUSCLES GET THE ENERGY THEY NEED TO WORK 1) Muscle needs energy to contract and as stated previously the ‘universal energy currency’ of living systems is ATP (adenosine triphosphate). This is largely produced within mitochondria‚ organelles which are often referred to as the ‘powerhouse’ of the cell. The ATP that results is used to provide the power for the muscle fibres to contract. Contraction itself (i.e. actual shortening movement) occurs when a bond is broken between ATP and one of its
