The bones tissue in young adults has high resistance to mechanical deformation.
Bones are the rigid body tissues consisting of cells embedded in an abundant, hard intercellular material.
The functions of the bones include:
1. Structural support for the action of soft tissues, such as contraction of muscles, expansion of lungs.
2. Protection of soft parts such as the brain.
3. Provision of protective site for specialized tissues such as the blood-forming system.
As we grow up, the bones too grow longer and thicker making us taller and heavier than before.
Joints are the structures that separate two or more adjacent elements of the skeleton.
Depending on the type of joint, each separated element may or may not move on one another.
Movements at joist are commonly produced by voluntary muscular action. Such movements are distinguished as “active”, as against those produced by the application of external force, whether by manipulation or by the energy of moving parts of gravity, which are known as “passive” movements.
Cartilage that acts as the grease between the bone joints.
