The muscular system is one of the most complex organ systems in the body‚ and it is imperative to the body’s survival‚ as it serves many significant functions‚ including movement‚ protection‚ posture‚ and heat production just to name a few. The muscular system has three types of muscle: skeletal‚ smooth‚ and cardiac. However‚ the main focus will be on the skeletal muscles and how they contract‚ as well as fatigue and respond to changes in temperature. In terms of the anatomy of the skeletal muscle

DIFFERENCE BETWEEN POISE AND POSTURE Posture and Poise Good Posture or Good Use? For many people‚ the Alexander Technique is closely associated with cultivating good posture. However the term posture is inadequate to convey what it is the Alexander Technique aims to improve. When it comes to posture‚ it is generally assumed that more uprightness is better and crooked is bad. There is relative truth in this. But striving for uprightness only brings about misuse in another guise: the straining

is a sodium deficit‚ the muscle will not be able to contract as well‚ decreasing the intensity at which you workout or perform. Exercise intensity is crucial in achieving muscular hypertrophy (gain in muscle mass). A sodium deficit in the body can also produce several negative side effects such as nausea‚ appetite loss‚ muscular weakness‚ and cramping. Gatorade conducted a study that compared the athletic performance of those who consumed Gatorade compared to water. They found that athletes who consumed

hold you upright. If your muscles all relaxed at the same time‚ you would collapse. You would not be able to survive without your muscular system. There are three types of muscle in your body: smooth muscle‚ cardiac muscle‚ and skeletal muscle. Smooth muscle is located in the digestive tract and in the walls of blood vessels. It moves food through the digestive system. Cardiac muscle is found only in the heart. This muscle pumps blood throughout your body. Skeletal muscle is attached to your

MUSCLE LAB REPORT ANATOMY& PHYSIOLOGY INTRODUCTION Muscle action is often described as departures from the standard position of the body‚ the anatomical position. Muscle fiber is an interaction of organelles and molecules within myosin binds to actin and exerts a pulling action. The result of this movement with myofibrils in which the filaments of actin and myosin slide past one another. This action shortens or contracts muscle fiber so that it pulls on its attachment. Muscle are stimulated
