Types of movements :
The cells of our human body display three types of movements, namely amoeboid, ciliary and muscular.
i. Amoeboid movement - Cells like macrophages and leucocytes in the blood exhibit amoeboid movement. Cytoskeletal elements like microfilaments are also involved in amoeboid movement.
ii. Ciliary movement - is shown by cells of our internal tubular organs which are lined by ciliated epithelium. The coordinated movements of cilia in the trachea help us in removing dust particles and some of the foreign substances inhaled alongwith the atmospheric air. Passage of ova through the female reproductive tract is also facilitated by the ciliary movement.
iii. Muscular movements - is shown by our limbs, jaws, tongue, etc, require muscular movement. The muscular movement is used for locomotion and other movements by human beings and majority of multicellular organisms.
