amoeboid ,ciliary and muscular movements.
Amoeboid or Pseudopodial Movements: Due to the streaming of protoplasm of cytoplasm, the surface of the cell forms false feet or pseudopodia. The old pseudopodia are replaced by the new pseudopodia and therefore the formation and withdrawal of it allows the cell to change its shape regularly. For example, in amoeba, WBCs and macrophages.
Ciliary Movements: The free surface of the cells have short fine hair like projections called cilia. The movement of these projections is called ciliary movements. The oar like activity of cilia creates a water current which helps in movement of various structures. The tubular structures of human body such as respiratory tract, reproductive tract are lined by ciliated epithelium. Spermatozoa and protozoa have flagella for locomotion and movement.
Muscular Movement: In humans, movement of limbs, jaw, tongue and other body parts occur due to contraction of muscles. The muscles contract and relax rhythmically to produce movement and are used effectively for locomotion.
