Physiology is how those various parts function “talk’’ to each other – their interactions and how they work on a cellular and multicellular level.
Bone.
There are three main elements to the composition of the bone.
Organic, Inorganic and Water.
• Organic consists of osteoid and bone cells - 25%.
• Inorganic consists of calcium phosphate mainly - 50%.
• Water also makes up 25% of the composition of the bone. (Riddle, J. 1985)
All bones are many different sizes and shapes and are made up of several different tissues. Each bone belongs to a particular category of bone:
Short, Long, Flat and Irregular. (Riddle, J. 1985) The bone is a solid system of living cells and fibers that are assisted by calcium salts. Bones also have blood vessels and nerves and other non materials.

Scoliosis is a condition that causes a persons spine to curve from side to side in the shape of an “s or c”. In most cases there is no known cause and this is called Idiopathic Scoliosis. People of all ages can develop Scoliosis, girls are more common to develop this than boys. Curvature of the spine can progressively get worse during the period of a growth spurt. There are a number of types of Scoliosis, these are:
• Congenital Scoliosis, this occurs at birth due to the spine not forming properly during pregnancy.
• Infantile Scoliosis, this occurs in children under the age of 3.
• Juvenile Scoliosis, this occurs in children between the ages of 4 – 10.
• Adolescent Scoliosis, this occurs in children between the ages of 11 – 18.
• Neuromuscular Scoliosis, this occurs due to a problem with the nervous system which intern affects the
