Answer:
Movement is the change in the position of a body part with respect to the whole body. It is one of the significant features of all living beings. The blinking of the eyes, breathing, eating are all examples of movement. So we can say that every second some or the other part of our body exhibits some or other kind of movements.
The human body movements get polished as we grow in age. The movement starts from crawling and with the increase in age the person starts walking leading to the movement of the whole organism.
These movements are possible because of joints. Joints are points in our body where two or more parts of our skeleton are connected together. Different joints help our body carry out different activities and movements.
All bones in our body form a framework and provide shape to our body. This framework is called a skeleton.
Our hand is made up of several small bones called Carpals.
Chest bones and backbone together form the ribcage. We have 12 ribs on each side of our chest. Our backbone consists of 33 small, disk-like bones called vertebrae. Rib Cage protects the internal parts of our body and provides a definite structure.
Bones in the shoulder are called shoulder bones and bones in the abdominal region are called pelvic bones.
Skull is made up of many bones which are fused together. It protects our brain. Cartilages are also part of our skeletal system and joints of the body. Unlike bones, they are soft and flexible.
Muscles are subjected to contraction and relaxation and work in pairs
