Joints are essential in allowing movement of the human body. They are located at the intersection of bones‚ and their structures determine the type of movement that will occur at that location. Each joint contains components of the skeletal and muscular systems and connective tissues that function together to allow movement to occur. A ball-and-socket joint is one example of a synovial joint. In a ball-and-socket joint‚ the round head of one bone rests within a cup-shaped depression in another

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

Skeletal System Skeletal system is the biological system providing support in living organisms. Skin‚ muscle and bones allow movement. Skin - pliable covering. Muscles do actual moving. Bones give anchor to move against. The skeleton functions not only as the support for the body but also in haematopoiesis‚ the manufacture of blood cells that takes place in bone marrow. This is why people who have cancer of the bone marrow almost always die. It is also necessary for protection of vital organs

A critical review of contemporary and popular reports within the ‘lay’ literature on the use of nutritional supplements for performance benefits. There is an endless list of ergogenic aids that claim to enhance sports performance that are religiously supplemented by amateur and professional athletes. Almost half of the general population have reported taking at least one form of dietary supplement‚ and the vast majority‚ if not all professional athletes use legal supplements‚ with a certain

Wave Summation (p. 21) - The combination of responses from a motor unit that has had two or more stimuli applied to it in quick succession. Tetanus (p. 21) - A state of continuous muscular contraction‚ especially when induced artificially by rapidly repeated stimuli. Muscle Fatigue (p . 23) - Muscle fatigue is the repeated‚ intense use of muscles which leads to a decline in performance.Though the actual mechanism for muscle fatigue
