3 A/ THE MUSCULOSKELETAL SYSTEM
Our musculoskeletal system consists of bones and muscles which share a primary function: movement of the body and its parts.
Bones are composed of osseous tissue which contains minerals that make the tissue hard and rigid. Before birth, bones are soft and composed mostly of cartilage and as an infant grows, bones become harder to bear the body weight. This process is called ossification. Bones are classified according to the shape: long, short, irregular and flat. The supporting framework for all organs is called the skeleton. It consists of 206 bones. The junction between two or more bones is called the joint. Functions of joints are to allow movement between bones. There are three types of joints: movable, partially movable and immovable.
There are over 500 muscles in the body: skeletal, cardiac and smooth. Skeletal muscles have three functions: movement of bones, maintenance of body posture, production of body heat. Cardiac muscle contracts to pump blood and smooth muscle in the walls of hollow organs contracts to move substances through the organs.
Try to explain ossification.
