ABSTRACT: Skeletal muscle is able to repair itself through regeneration. However‚ an injured muscle often does not fully recover its strength because complete muscle regeneration is hindered by the development of fibrosis. Biological approaches to improve muscle healing by enhancing muscle regeneration and reducing the formation of fibrosis are being investigated. Previously‚ we have determined that insulin-like growth factor–1 (IGF-1) can improve muscle regeneration in injured muscle. We also

Osteoporosis‚ Osteoarthritis‚ and Muscular Atrophy Osteoporosis and Osteoarthritis are both diseases of the bone. Osteoporosis actually means “porous bones” and is a problem with bones where there isn’t enough calcium in them to give them strength. This is because the bone cells aren’t being reproduced as fast as the bone is aging or deteriorating which causes the bones to become fragile. This can happen because of loss of calcium in the bone‚ or a problem with the calcium being absorbed correctly

Spinal Muscular Atrophy also known as SMA is a genetic disease affecting the part of the nervous system that controls the voluntary muscle movement. It can be passed down from parent to child. The major causes of SMA is a deficiency of a motor neuron protein called SMN. Mutation in the survival motor neuron gene 1. The symptoms of SMA are very sad a child is weak and has a delay in meeting feeding and breathing development milestones. There are four types of SMA‚ type 0 is the most severe it can

The Human Skeletal System Introduction The human skeletal system is comprised of both fused and individual bones; supported and supplemented by ligaments‚ tendons‚ muscles and cartilage. The skeletons purpose is to protect and support the delicate internal organs and provide a framework that allows the body to stand upright and move. It also produces blood cells and stores minerals that our body needs to function effectively. The skeletal system is a very important part of the human body. Without

The maintenance of blood pH is called acid-base homeostasis. Acid-base homeostasis is a complex synergy that involving lungs‚ kidneys and a buffer chemical in blood and blood cells.

+Amendments for D2: Skeletal muscles allows for many different types of muscle contractions such as eccentric‚ concentric‚ isometric and isokinetic. These muscles are voluntary and the contractions produced have a huge impact on Wilkinson’s game. For example when he is striking a ball his quadricep contracts concentrically to produce force onto the ball. The more powerful the muscle the bigger the contraction‚ therefore if Johnny improves the strength of his quadriceps his kicking distance could
