Movement in Human Body
Movement is one of the significant features of all living beings. We move our hands for doing many kinds of work, tongue for talking, jaws and teeth while eating. The movements of our eyelids are an involuntary function. So we can say that every second some or the other part of our body exhibit some or other kind of movements.
Some type of movements result in the change of place, they are termed as locomotion. Walking, cycling. running, and swimming is some of the locomotory movements. There are different types of locomotory movements in different organisms like paramecium have cilia which help in capturing food and also in locomotion. Hydra has tentacles for capturing prey and for locomotion. We use our limbs for different types of movements. Locomotion is necessary for food, shelter etc.
Let us now study about the different types of movements of the cells of our body.
Some cells of our body like the white blood cells exhibit amoeboid movement.
Cytoskeletons and microfilaments are also involved in this type of movement. Some of our internal tubular organs exhibit ciliary movement. Cilia are present in our trachea which helps in removing foreign particles, dust etc. The movement of ova in the female reproductive tract is also a type of ciliary movement.
Whenever we move, our limbs are involved. They are the muscular movements. In locomotion and other types of movements in humans, the contractile property of the muscles is used. Movements involve a perfect coordination of the muscular, skeletal and neural system. There are a variety of muscles and joints involved in movements.
