Movement is when the living organism moves a body part or parts to bring without a change in the position of the organisms.

Types of Movement

Amoeboid Movement – Some specialized cells in our body, such as macrophages and leukocytes in our blood, show amoeboid movement. It is affected by the pseudopodia formed by the protoplasm, as in Amoeba. The amoeboid movement also involves Cytoskeletal elements such as microfilaments.

Ciliary Movement – Ciliary movement occurs in many of our tubular internal organs bound by the ciliated epithelium. The integrated movement of the cilia in the trachea helps to disperse the dust particles and other foreign substances inhaled with air. Transmission of ova through the female reproductive tract is also driven by the ciliary movement.

• This involves the synchronised movement of the cilia in order to bring about its functions.
• For instance, the cilia lining the fallopian tubes are responsible for the movement of the ovum released by the ovary.
• They transport the released ovum to the ampullary region of the fallopian tube where it fuses with the sperm to get fertilised.
• The cilia lining the respiratory tract are laden with mucus and are crucial for trapping any pollutant that might gain entry into the lungs via inhalation.

Muscular Movement – Movement of our eyelids, jaws, hands, legs, etc requires muscular movement. The contractile property of muscles is effectively used for locomotion and other movements by human beings and almost all other multicellular organisms. A perfect coordinated activity of muscular, skeletal, and neural systems is essential for muscular movement.
